The present invention relates to communication devices. In particular, but not by way of limitation, the present invention relates to bulk onboarding of communication devices
The Internet is a global system of interconnected computers and computer networks that use a standard Internet protocol suite (e.g., the Transmission Control Protocol (TCP) and Internet Protocol (IP)) to communicate with each other. The Internet of Things (IoT) is based on the idea that everyday objects, not just computers and computer networks, can be readable, recognizable, locatable, addressable, and controllable via an IoT communications network (e.g., an ad-hoc system or the Internet).
A number of market trends are driving development of IoT devices. For example, increasing energy costs are driving governments' strategic investments in smart grids and support for future consumption, such as for electric vehicles and public charging stations. Increasing health care costs and aging populations are driving development for remote/connected health care and fitness services. A technological revolution in the home is driving development for new “smart” services, including consolidation by service providers marketing ‘N’ play (e.g., data, voice, video, security, energy management, etc.) and expanding home networks. Buildings are getting smarter with appurtenances more convenient to control as a means to reduce operational costs for enterprise facilities.
There are a number of key applications for the IoT. For example, in the area of smart grids and energy management, utility companies can optimize delivery of energy to homes and businesses while customers can better manage energy usage. In the area of home and building automation, smart homes and buildings can have centralized control over virtually any device or system in the home or office, from appliances to plug-in electric vehicle (PEV) security systems. In the field of asset tracking, enterprises, hospitals, factories, and other large organizations can accurately track the locations of high-value equipment, patients, vehicles, and so on. In the area of health and wellness, doctors can remotely monitor patients' health while people can track the progress of fitness routines.
Accordingly, in the near future, increasing development in IoT technologies will lead to numerous IoT devices surrounding a user at home, in vehicles, at work, and many other locations. As more and more devices become network-aware, problems that relate to configuring devices to access wireless networks will therefore become more acute. In particular, existing mechanisms to configure devices to access wireless networks tend to suffer from various drawbacks and limitations, which include a complex user experience, insufficient reliability, and security vulnerabilities, among other things. For example, configuring devices to access infrastructure-mode Wi-Fi networks and other similar wireless networks typically requires association and authentication of the device.
In certain cases, a process called “onboarding” may be used to accomplish the secure admission to the wireless network, wherein onboarding may allow thin client devices, headless devices, and other devices that may presumably lack a friendly user interface to learn sufficient information about the destination wireless network to accomplish the admission and authentication processes required to join the wireless network. However, if many devices need to be onboarded (e.g., 100 devices), the process of connecting to each device, and have a Wi-Fi network connect, disconnect, and validate the devices is, at the very least, cumbersome.
A more complete appreciation of aspects of the disclosure and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings which are presented solely for illustration and not limitation of the disclosure, and in which:
An aspect of the present disclosure provide a method for the distributed bulk onboarding of devices onto a Wi-Fi network. The method may comprise receiving, at an onboarding device, Wi-Fi configuration information. Then, it may comprise detecting, at the onboarding device, broadcast information from a plurality of devices that may be onboarded onto the Wi-Fi network, the broadcast information indicating that one or more of the plurality of devices is an onboarding node capable of onboarding another of the plurality of devices. The method may further comprise creating instructions indicating an order in which the plurality of devices may be onboarded, and by which of the one or more onboarding nodes each of the remaining devices of the plurality shall be onboarded, and providing the Wi-Fi configuration information and at least a portion of the instructions to at least one of the onboarding nodes to enable onboarding at least one device of the plurality of devices.
Another aspect of the disclosure provides a system for distributed bulk onboarding of a plurality of communication devices onto a Wi-Fi network. The system may comprise three or more communication devices. A first one of the communication devices may be a bulk onboarding configuration device and at least one second one of the other communication devices may be an onboarding node capable of onboarding at least a third one of the communication devices. In the system, the bulk onboarding communication device may be adapted to receive Wi-Fi configuration information, detect broadcast information from the plurality of communication devices that can be onboarded onto the Wi-Fi network, and create instructions that indicate the order in which the plurality of communication devices should be onboarded; In the system, the onboarding node may be adapted to receive the Wi-Fi configuration information from the bulk onboarding communication device, connect to the Wi-Fi network, and receive at least a portion of the instructions. The portion of the instructions may instruct the onboarding node to provide the Wi-Fi configuration information to the third communication device. Also within the system, the third communication device may be adapted to receive the Wi-Fi configuration information and connect to the Wi-Fi network using the configuration information.
Yet another aspect of the disclosure provides a non-transitory, tangible processor readable storage medium, encoded with processor readable instructions to perform a method for the distributed bulk onboarding of devices onto a Wi-Fi network. The method may comprise receiving, at an onboarding device, Wi-Fi configuration information. Then, it may comprise detecting, at the onboarding device, broadcast information from a plurality of devices that may be onboarded onto the Wi-Fi network, the broadcast information indicating that one or more of the plurality of devices is an onboarding node capable of onboarding another of the plurality of devices. The method may further comprise creating instructions indicating an order in which the plurality of devices may be onboarded, and by which of the one or more onboarding nodes each of the remaining devices of the plurality shall be onboarded, and providing the Wi-Fi configuration information and at least a portion of the instructions to at least one of the onboarding nodes to enable onboarding at least one device of the plurality of devices.

In one embodiment, the supervisor device 130 may generally observe, monitor, control, or otherwise manage the various other components in the wireless communications system 100B. For example, the supervisor device 130 can communicate with an access network (e.g., access point 125) over air interface 108 and/or a direct wired connection 109 to monitor or manage attributes, activities, or other states associated with the various IoT devices 110-120 in the wireless communications system 100B. The supervisor device 130 may have a wired or wireless connection to the Internet 175 and optionally to the IoT server 170 (shown as a dotted line). The supervisor device 130 may obtain information from the Internet 175 and/or the IoT server 170 that can be used to further monitor or manage attributes, activities, or other states associated with the various IoT devices 110-120. The supervisor device 130 may be a standalone device or one of IoT devices 110-120, such as computer 120. The supervisor device 130 may be a physical device or a software application running on a physical device. The supervisor device 130 may include a user interface that can output information relating to the monitored attributes, activities, or other states associated with the IoT devices 110-120 and receive input information to control or otherwise manage the attributes, activities, or other states associated therewith. Accordingly, the supervisor device 130 may generally include various components and support various wired and wireless communication interfaces to observe, monitor, control, or otherwise manage the various components in the wireless communications system 100B.
The wireless communications system 100B shown in
For example, passive IoT devices 105 may include a coffee cup and a container of orange juice that each have an RFID tag or barcode. A cabinet IoT device and the refrigerator IoT device 116 may each have an appropriate scanner or reader that can read the RFID tag or barcode to detect when the coffee cup and/or the container of orange juice passive IoT devices 105 have been added or removed. In response to the cabinet IoT device detecting the removal of the coffee cup passive IoT device 105 and the refrigerator IoT device 116 detecting the removal of the container of orange juice passive IoT device, the supervisor device 130 may receive one or more signals that relate to the activities detected at the cabinet IoT device and the refrigerator IoT device 116. The supervisor device 130 may then infer that a user is drinking orange juice from the coffee cup and/or likes to drink orange juice from a coffee cup.
Although the foregoing describes the passive IoT devices 105 as having some form of RFID tag or barcode communication interface, the passive IoT devices 105 may include one or more devices or other physical objects that do not have such communication capabilities. For example, certain IoT devices may have appropriate scanner or reader mechanisms that can detect shapes, sizes, colors, and/or other observable features associated with the passive IoT devices 105 to identify the passive IoT devices 105. In this manner, any suitable physical object may communicate its identity and attributes and become part of the wireless communication system 100B and be observed, monitored, controlled, or otherwise managed with the supervisor device 130. Further, passive IoT devices 105 may be coupled to or otherwise made part of the wireless communications system 100A in

The IoT devices 110-118 make up an IoT group 160. An IoT device group 160 is a group of locally connected IoT devices, such as the IoT devices connected to a user's home network. Although not shown, multiple IoT device groups may be connected to and/or communicate with each other via an IoT SuperAgent 140 connected to the Internet 175. At a high level, the supervisor device 130 manages intra-group communications, while the IoT SuperAgent 140 can manage inter-group communications. Although shown as separate devices, the supervisor device 130 and the IoT SuperAgent 140 may be, or reside on, the same device (e.g., a standalone device or an IoT device, such as computer 120 in
Each IoT device 110-118 can treat the supervisor device 130 as a peer and transmit attribute/schema updates to the supervisor device 130. When an IoT device needs to communicate with another IoT device, it can request the pointer to that IoT device from the supervisor device 130 and then communicate with the target IoT device as a peer. The IoT devices 110-118 communicate with each other over a peer-to-peer communication network using a common messaging protocol (CMP). As long as two IoT devices are CMP-enabled and connected over a common communication transport, they can communicate with each other. In the protocol stack, the CMP layer 154 is below the application layer 152 and above the transport layer 156 and the physical layer 158.
In accordance with another aspect of the disclosure,
The Internet 175 is a “resource” that can be regulated using the concept of the IoT. However, the Internet 175 is just one example of a resource that is regulated, and any resource could be regulated using the concept of the IoT. Other resources that can be regulated include, but are not limited to, electricity, gas, storage, security, and the like. An IoT device may be connected to the resource and thereby regulate it, or the resource could be regulated over the Internet 175.
IoT devices can communicate with each other to regulate their use of a resource 180. For example, IoT devices such as a toaster, a computer, and a hairdryer may communicate with each other over a Bluetooth communication interface to regulate their use of electricity (the resource 180). As another example, IoT devices such as a desktop computer, a telephone, and a tablet computer may communicate over a Wi-Fi communication interface to regulate their access to the Internet 175 (the resource 180). As yet another example, IoT devices such as a stove, a clothes dryer, and a water heater may communicate over a Wi-Fi communication interface to regulate their use of gas. Alternatively, or additionally, each IoT device may be connected to an IoT server, such as IoT server 170, which has logic to regulate their use of the resource 180 based on information received from the IoT devices.
In accordance with another aspect of the disclosure,
The communications system 100E includes two IoT device groups 160A and 160B. Multiple IoT device groups may be connected to and/or communicate with each other via an IoT SuperAgent connected to the Internet 175. At a high level, an IoT SuperAgent may manage inter-group communications among IoT device groups. For example, in

While internal components of IoT devices, such as IoT device 200, can be embodied with different hardware configurations, a basic high-level configuration for internal hardware components is shown as platform 202 in
Accordingly, an aspect of the disclosure can include an IoT device (e.g., IoT device 200) including the ability to perform the functions described herein. For example, the processor 208, in conjunction with the transceiver 206 may broadcast a software-enabled access point, or a “SoftAP,” which is an interface that may allow the onboarding of other devices onto a Wi-Fi network. As will be appreciated by those skilled in the art, the various logic elements can be embodied in discrete elements, software modules executed on a processor (e.g., processor 208) or any combination of software and hardware to achieve the functionality disclosed herein. For example, transceiver 206, processor 208, memory 212, and I/O interface 214 may all be used cooperatively to load, store and execute the various functions disclosed herein and thus the logic to perform these functions may be distributed over various elements. Alternatively, the functionality could be incorporated into one discrete component. Therefore, the features of the IoT device 200 in

Although the foregoing describes the passive IoT device 300 as having some form of RF, barcode, or other I/O interface 314, the passive IoT device 300 may comprise a device or other physical object that does not have such an I/O interface 314. For example, certain IoT devices may have appropriate scanner or reader mechanisms that can detect shapes, sizes, colors, and/or other observable features associated with the passive IoT device 300 to identify the passive IoT device 300. In this manner, any suitable physical object may communicate its identity and attributes and be observed, monitored, controlled, or otherwise managed within a controlled IoT network.

Generally, unless stated otherwise explicitly, the phrase “logic configured to” as used throughout this disclosure is intended to invoke an aspect that is at least partially implemented with hardware, and is not intended to map to software-only implementations that are independent of hardware. Also, it will be appreciated that the configured logic or “logic configured to” in the various blocks are not limited to specific logic gates or elements, but generally refer to the ability to perform the functionality described herein (either via hardware or a combination of hardware and software). Thus, the configured logics or “logic configured to” as illustrated in the various blocks are not necessarily implemented as logic gates or logic elements despite sharing the word “logic.” Other interactions or cooperation between the logic in the various blocks will become clear to one of ordinary skill in the art from a review of the aspects described below in more detail.
The various embodiments may be implemented on any of a variety of commercially available server devices, such as server 500 illustrated in
Although aspects of the disclosure allow for the distributed bulk onboarding of Wi-Fi enabled devices which may be discovered through existing Wi-Fi discovery protocols, including those currently known in the art, such as Simple Service Discovery Protocol (SSDP), Link Layer Discovery Protocol (LLDP), Neighbor Discovery Protocol (NDP), Universal Plug-N-Play (UPnP), it is contemplated that certain devices within a potential Wi-Fi network may also be easily discoverable to each other through P2P services. In various embodiments, it may be easier or more efficient for devices to communicate to each other via discoverable P2P services rather than Wi-Fi discovery.
According to one aspect of the disclosure,
In one embodiment, the distributed bus 625 may be supported by a variety of transport protocols (e.g., Bluetooth, TCP/IP, Wi-Fi, CDMA, GPRS, UMTS, etc.). For example, according to one aspect, a first device 610 may include a distributed bus node 612 and one or more local endpoints 614, wherein the distributed bus node 612 may facilitate communications between local endpoints 614 associated with the first device 610 and local endpoints 634 and 644 associated with a second device 630 and a third device 640 through the distributed bus 625 (e.g., via distributed bus nodes 632 and 642 on the second device 630 and the third device 640). As will be described in further detail below with reference to
According to one aspect of the disclosure,
In one embodiment, the bus nodes 712 and 732 may perform a suitable discovery mechanism at message sequence step 754. For example, mechanisms for discovering connections supported by Bluetooth, TCP/IP, UNIX, or the like may be used. At message sequence step 756, the local endpoint 714 on Device A 710 may request to connect to an entity, service, endpoint etc., available through bus node 712. In one embodiment, the request may include a request-and-response process between local endpoint 714 and bus node 712. At message sequence step 758, a distributed message bus may be formed to connect bus node 712 to bus node 732 and thereby establish a P2P connection between Device A 710 and Device B 730. In one embodiment, communications to form the distributed bus between the bus nodes 712 and 732 may be facilitated using a suitable proximity-based P2P protocol (e.g., the AllJoyn™ software framework designed to enable interoperability among connected products and software applications from different manufacturers to dynamically create proximal networks and facilitate proximal P2P communication). Alternatively, in one embodiment, a server (not shown) may facilitate the connection between the bus nodes 712 and 732. Furthermore, in one embodiment, a suitable authentication mechanism may be used prior to forming the connection between bus nodes 712 and 732 (e.g., SASL authentication in which a client may send an authentication command to initiate an authentication conversation). Still further, during message sequence step 758, bus nodes 712 and 732 may exchange information about other available endpoints (e.g., local endpoints 644 on Device C 640 in
In one embodiment, at message sequence step 760, bus node 712 and bus node 732 may use obtained information associated with the local endpoints 734 and 714, respectively, to create virtual endpoints that may represent the real obtained endpoints available through various bus nodes. In one embodiment, message routing on the bus node 712 may use real and virtual endpoints to deliver messages. Further, there may one local virtual endpoint for every endpoint that exists on remote devices (e.g., Device A 710). Still further, such virtual endpoints may multiplex and/or de-multiplex messages sent over the distributed bus (e.g., a connection between bus node 712 and bus node 732). In one aspect, virtual endpoints may receive messages from the local bus node 712 or 732, just like real endpoints, and may forward messages over the distributed bus. As such, the virtual endpoints may forward messages to the local bus nodes 712 and 732 from the endpoint multiplexed distributed bus connection. Furthermore, in one embodiment, virtual endpoints that correspond to virtual endpoints on a remote device may be reconnected at any time to accommodate desired topologies of specific transport types. In such an aspect, UNIX based virtual endpoints may be considered local and as such may not be considered candidates for reconnection. Further, TCP-based virtual endpoints may be optimized for one hop routing (e.g., each bus node 712 and 732 may be directly connected to each other). Still further, Bluetooth-based virtual endpoints may be optimized for a single pico-net (e.g., one master and n slaves) in which the Bluetooth-based master may be the same bus node as a local master node.
At message sequence step 762, the bus node 712 and the bus node 732 may exchange bus state information to merge bus instances and enable communication over the distributed bus. For example, in one embodiment, the bus state information may include a well-known to unique endpoint name mapping, matching rules, routing group, or other suitable information. In one embodiment, the state information may be communicated between the bus node 712 and the bus node 732 instances using an interface with local endpoints 714 and 734 communicating with using a distributed bus based local name. In another aspect, bus node 712 and bus node 732 may each may maintain a local bus controller responsible for providing feedback to the distributed bus, wherein the bus controller may translate global methods, arguments, signals, and other information into the standards associated with the distributed bus. At message sequence step 764, the bus node 712 and the bus node 732 may communicate (e.g., broadcast) signals to inform the respective local endpoints 714 and 734 about any changes introduced during bus node connections, such as described above. In one embodiment, new and/or removed global and/or translated names may be indicated with name owner changed signals. Furthermore, global names that may be lost locally (e.g., due to name collisions) may be indicated with name lost signals. Still further, global names that are transferred due to name collisions may be indicated with name owner changed signals and unique names that disappear if and/or when the bus node 712 and the bus node 732 become disconnected may be indicated with name owner changed signals.
As used above, well-known names may be used to uniquely describe local endpoints 714 and 734. In one embodiment, when communications occur between Device A 710 and Device B 730, different well-known name types may be used. For example, a device local name may exist only on the bus node 712 associated with Device A 710 to which the bus node 712 directly attaches. In another example, a global name may exist on all known bus nodes 712 and 732, where only one owner of the name may exist on all bus segments. In other words, when the bus node 712 and bus node 732 are joined and any collisions occur, one of the owners may lose the global name. In still another example, a translated name may be used when a client is connected to other bus nodes associated with a virtual bus. In such an aspect, the translated name may include an appended end (e.g., a local endpoint 714 with well-known name “org.foo” connected to the distributed bus with Globally Unique Identifier “1234” may be seen as “G1234.org.foo”).
At message sequence step 766, the bus node 712 and the bus node 732 may communicate (e.g., broadcast) signals to inform other bus nodes of changes to endpoint bus topologies. Thereafter, traffic from local endpoint 714 may move through virtual endpoints to reach intended local endpoint 734 on Device B 730. Further, in operation, communications between local endpoint 714 and local endpoint 734 may use routing groups. In one aspect, routing groups may enable endpoints to receive signals, method calls, or other suitable information from a subset of endpoints. As such, a routing name may be determined by an application connected to a bus node 712 or 732. For example, a P2P application may use a unique, well-known routing group name built into the application. Further, bus nodes 712 and 732 may support registering and/or de-registering of local endpoints 714 and 734 with routing groups. In one embodiment, routing groups may have no persistence beyond a current bus instance. In another aspect, applications may register for their preferred routing groups each time they connect to the distributed bus. Still further, groups may be open (e.g., any endpoint can join) or closed (e.g., only the creator of the group can modify the group). Yet further, a bus node 712 or 732 may send signals to notify other remote bus nodes or additions, removals, or other changes to routing group endpoints. In such embodiments, the bus node 712 or 732 may send a routing group change signal to other group members whenever a member is added and/or removed from the group. Further, the bus node 712 or 732 may send a routing group change signal to endpoints that disconnect from the distributed bus without first removing themselves from the routing group.
According to an aspect of the disclosure,
The onboarder device 820 is designated as a node and comprises a SoftAP 850, The SoftAP 850 comprises several components, which will be described in further detail presently, that execute the processes relating to providing the configuration information of a Wi-Fi network from an onboarder device 820 to an onboardee device 810. One component of the SoftAP 850 may be a discovery/broadcast component 835, which allows other devices to discover that the onboarder device 820 comprises a SoftAP and is capable of onboarding other devices. This discovery/broadcast component 835 may allow discovery, by known and yet-to-be-implemented Wi-Fi discovery protocols, of discoverable P2P services as described throughout this disclosure.
In an embodiment, the onboarder device 820 and the onboardee device 810 may run respective onboarding applications 812, 822 that communicate with respective peer-to-peer (P2P) platforms (not shown) that may exist in that provide the discoverable P2P services that may facilitate the remote onboarding (e.g., the AllJoyn™ software framework mentioned above). As such, the onboardee device 810 and the onboarder device 820 may communicate with one another using the mechanisms described in further detail above to form a distributed bus (not shown) between the discovery/broadcast components 825 and 835 that may enable communication between the respective onboarding applications 812, 822, which may correspond to the local endpoints described above in connection with
As such, the daemons may generally run in one or more background processes and the onboarding applications 812, 822, the onboarding manager 818, and the remote onboarding manager 819 may run in separate processes, whereby the onboarding applications 812, 822, the onboarding manager 818, and the remote onboarding manager 819 may have respective local “bus attachments” that represent the local host daemon and handle message routing therebetween. Alternatively, in certain cases, the onboardee device 810 may be a thin client, an embedded device, or another device that has a constrained operating environment (e.g., limited size, memory, processor speed, power, peripherals, user interfaces, etc.). As such, where the onboardee device 810 has limited capabilities, bundling local bus attachments into each application or service that uses the P2P platform 814 may interfere with performance (e.g., because substantial bus attachments may require substantial network connections, memory, etc.). In these cases, rather than having a local bus attachment within the onboarding application 822 and/or the onboarding service 823, the onboarding application 822 may instead employ a thin client application program interface and the P2P platform (not shown) may instead employ a thin client process that utilizes the host daemon on the onboardee device 810 running the onboarding application 812. However, in either case, the call flows and behavior that occur between the onboardee device 810 and the onboarder device 820 to configure and validate the onboardee device 810 in order to access the Wi-Fi network may be substantially the same whether the onboarding application 812 implements a local bus attachment to communicate with the host daemon or communicates directly with the host daemon.
Having provided the above overview relating to the system architecture in which devices broadcasting SoftAPs may be used for distributed bulk onboarding of other devices broadcasting SoftAPs as well as client-only onboardee devices over a Wi-Fi network, various aspects that relate to the specific mechanisms that may be used to allow distributed bulk onboarding will now be described.
As depicted, the first node 810A and second node 810B have identical logical components, including all components that comprise or interact with the SoftAPs 840A and 840B. The first node 810A and second node 810B are depicted to illustrate that the second node 810B can first be an onboardee device when it is given the necessary Wi-Fi configuration information from the SoftAP 840A of onboarder device 810A. Then, the second node 810B can become the onboarder device in relation to the leaf/onboardee device 810C. The first node 810A is characterized at least in part by the fact that it has an onboarding “service” 813A as part of its onboarding application 812A. The onboarding service 813A may have functionality to provide Wi-Fi configuration information to another device. The onboarder device 810A may also have an onboarding client (not shown) as part of its onboarding application 812A, the client having functionality to accept Wi-Fi configuration information from another device. The second node 810B is depicted as having an onboarding service/client 813 as part of its onboarding application 812B that operates as a service and a client. Both the onboarder device 810A and the onboarder/onboardee device 810B, therefore, have the appropriate onboarding services that allows them to provide Wi-Fi credentials to another device. The presence of this kind of onboarding service distinguishes the devices as ones that broadcast SoftAPs (e.g., 840A, 840B). In contrast, the leaf onboardee device 810C does not have an onboarding service, but rather only an onboarding client 813C as part of its onboarding application 812C. Therefore, it cannot be characterized as broadcasting a SoftAP, and is not depicted as having one. A Wi-Fi capable device may not have an onboarding service for a number of reasons, such as that it is constrained in power, memory, or function. However, Wi-Fi connected devices generally need at least some kind of onboarding client interface in order to be connected to a Wi-Fi network at all.
Bulk onboarding of devices refers to onboarding a plurality of devices. There need not be a particular number of devices in a network to qualify as “bulk,” but for the purposes of this disclosure, it is contemplated that at least three devices may be used to perform the bulk onboarding method. Throughout this disclosure, the terms “onboarding” and “configuring” may be used interchangeably. In the depicted method, an algorithm that may be referred to as a “divide and conquer algorithm,” is applied to solve the problem of bulk onboarding of devices, and to reduce the time it takes to configure many devices to the same Wi-Fi network. It is known in the art that the process of onboarding, or configuring the Wi-Fi connectivity of a single device can take up to 30-60 seconds. Configuring, as described with reference to
Many homes and businesses typically create secure Wi-Fi networks comprising at least one Wi-Fi router to connect to the internet. When a user first sets up a new Wi-Fi router, usually at least one computer with a user interface must be used to establish security credentials, such as an SSID (Service Set Identifier, or network name), an encryption level, and a password of the router in order to allow future devices to be onboarded onto the secure Wi-Fi network. This process typically requires the user to open a router administration tool on the computer user interface, log in to the router, and enter internet connection information. In some cases, if the router is replacing an old router, the user may need to update the MAC (media access control) address as well. Then the user must verify that the internet connection is working. The configuration of the computer itself to the network via the router may take place through the same setup tool with a few more steps. At this point, the wireless router is connected to the internet and has established security credentials for devices that will be configured to it, and the first computer is configured to the secure wireless network by verifying those security credentials. Additional devices that are connected to the Wi-Fi network each need to be configured with the SSID, encryption level, and password as well. Often, this process is accomplished during the initial set-up of the device. For example, a wireless printer may have its own graphical user interface, or it may use an installation driver visible on a computer that it is wirelessly connected to in order to be configured to the Wi-Fi network. That is, the user may either input all the configuration credentials through a user interface on the printer hardware itself, or the user may input the configuration credentials through an interface on the computer.
As another example, many entertainment systems now connect to a secure home Wi-Fi network. Many “smart TVs” have integrated Wi-Fi radios. Such TVs are often configured using the TV screen itself as the interface. Many smart TV users also use specific content-streaming devices (such as Apple TV®, Google Chromecast®, and Roku®) to play audio and video content from websites (such as Netflix®, Hulu®, Amazon® iTunes®) on the TV. Often, the content streaming devices themselves have built-in Wi-Fi radios, on which credentials may be entered either through the TV, through an interface on a connected computer, or on an interface on a user's mobile device.
As IoT devices become more popular, it is possible that a single home may have dozens of IoT devices connected on a single secure WiFi network. For example, a home may have multiple desktop computers, printers, tablet computers, mobile phones, but may also have several more IoT devices connected over WiFi. Many IoT devices do not have user interfaces (e.g., passive IoT device 200B), yet they connect to Wi-Fi. These devices often need to be configured through an interface on a mobile communication device (such as a smartphone or tablet) or another type of computing device.
Businesses with asset tracking systems may have hundreds of IoT devices within one facility. It is possible that certain scenarios could cause all, or most, of the devices in a single home or business to be off-boarded at once. For example, in the case of a power outage, devices that rely on mains AC power may be reset, and even battery-powered IoT devices may need new configuration information if the main Wi-Fi router itself was knocked offline. There are other scenarios in which it may be desirable to change security settings or other configuration settings of a secure Wi-Fi network, but doing so would cause many devices to be off-boarded because the devices would no longer have the correct security credentials. As security of Wi-Fi networks, and cybersecurity in general become of greater concern, individuals and companies may desire to change security credentials more frequently. For example, users may wish to upgrade their Wi-Fi routers, or to change their passwords at given time intervals, or to change other security settings based on a specific security threat.
In order to accomplish the efficient and secure onboarding of multiple devices on a secure Wi-Fi network, the present disclosure provides a system and method for distributed bulk onboarding. Turning now to
Another aspect of the configuration tool 1004 is the device list 1008. The device list 1008 may present the user with a possible list of devices to onboard. Devices that appear on the device list 1008 may be devices that are within the Wi-Fi signal range of the router and present at least an onboarding client interface (such as the onboarding client 813 of

Within a given secure Wi-Fi network, such as a home or a business, several network devices may have the capability to be Soft APs. Soft APs, as discussed in some detail previously, allow computing devices to become wireless access points and act like Wi-Fi routers or “hotspots” themselves. There are some devices (i.e., Wi-Fi routers) that are sold as dedicated access points, or repeaters, for the purposes of increasing the transmission range of a single secure Wi-Fi network and could be characterized as a SoftAP, but a SoftAP as generally used in this disclosure refers to a device with at least a Wi-Fi transceiver (e.g., transceiver 206 of
An aspect of the disclosure is that devices with Soft APs may be used to facilitate distributed bulk onboarding of devices in a network.
Wi-Fi signal strength between devices can depend on several factors. For signal strength between the Wi-Fi router 1201 itself and any device in the network, signal strength may be impacted by the physical distance between the objects, physical barriers deflecting the signal, and the capability of the network adapter or Wi-Fi radio on the device itself. Referring briefly back to
Turning back to
To begin the process of bulk onboarding all the devices on the network 1200, the smartphone 1202 may be onboarded first, in many embodiments. It is contemplated that in these embodiments, the smartphone 1202 is onboarded first because it is the bulk onboarding configuration device. In order to determine an efficient way of onboarding all the devices within the potential Wi-Fi network 1200, the smartphone 1202 may first create a tree of all the potential nodes and leaves throughout the network. In order to create a tree, the smartphone 1202 may receive information that is broadcasted (or is otherwise discoverable) from individual devices. This information indicates what devices are within range of the Wi-Fi router 1201, which of those devices have SoftAPs (nodes), and which devices may be Wi-Fi clients-only (leaves). Additionally, this information may include the signal strength as between the Wi-Fi-router and SoftAP devices. This signal strength is not only a function of the strength of the Wi-Fi router's radio and the distance to a particular SoftAP device, but also a function of the strength of a particular SoftAP device's wireless radio. Various devices may have wireless radios that broadcast and receive signals at different IEEE 802.11 standards. For example, a newer desktop computer, such as desktop computer 1203 may have a dual-band wireless radio that broadcasts at the 2.4 GHz and 5 GHz ISM bands, whereas a less robust IoT device, such as IoT device 1204 may only broadcast at the 2.4 GHz band, which is more prone to interference and network traffic.
The signal strength information about various SoftAPs in the network may be relevant to determine which nodes may be most efficient in onboarding other nearby devices. Another piece of information regarding signal strength may include the signal strength as between any SoftAP that may be used to onboard a client-only device (i.e., one that does not have a SoftAP) and the client-only device itself. The signal strength may be a function of the SoftAP wireless radio and the distance between a node and a particular client. It is contemplated that all devices that may be onboarded to the network 1200 have a wireless radio that broadcasts and receives at least at the 2.4 GHz band. The signal strength or distance between a SoftAP node and various clients may be relevant to determine which client to onboard first so that the overall distributed bulk onboarding process is most efficient. The process is “distributed” in the sense that the responsibility for onboarding devices to the network is distributed among more devices than just the Wi-Fi router. The process may be efficient in the sense that the onboarding of all the devices saves one or more of time, battery/electrical power, processing resources, and data transmission.
The information received by the smartphone 1202 regarding the devices in the network 1200 may be acquired by various discovery protocols, including those currently known in the art, such as Simple Service Discovery Protocol (SSDP), Link Layer Discovery Protocol (LLDP), Neighbor Discovery Protocol (NDP), Universal Plug-N-Play (UPnP), and other existing and yet-to-be-implemented discovery protocols that allow for network devices to broadcast and/or discover identities, locations, capabilities, and/or services. The discovery or broadcast of each device in a network may be implemented by a logical component such as the discovery/broadcast component 835 of
Based on the information about the devices on the network 1200, the smartphone 1202 can then construct a map of a tree for efficiently onboarding all of the devices. The tree may include all of the nodes and leaves in the network 1200. Throughout this disclosure, the concept of a tree describes a set of information or instructions that specify where devices in a network are in relationship to each other in terms of physical distance and/or signal strength. Additionally the tree information identifies which devices in a potential network broadcast SoftAPs and identifies one or more efficient pathways between all the devices that would result in the onboarding of all the devices. In
Once the Wi-Fi router 1201 has onboarded the smartphone 1202 and the tree mapping component 1104 has created a tree indicating what kinds of devices are in the network and where they are located, the smartphone may send instructions back to the Wi-Fi router 1201 that include the map and/or instructions of which device to onboard next. The tree map is alternatively referred to as tree “instructions.” The tree map or instructions may comprise various forms, as will be described in further detail throughout the disclosure. An aspect of the disclosure is that when one node onboards another node, the onboarding node provides the tree map or instructions to the onboardee node, so that the onboardee node knows which devices it should onboard itself (that is, the onboardee becomes the onboarder). In the example of
In
In order to better illustrate the order in which the devices in
At the third level 1263, the laptop computer 1211, the desktop computer 1203, the smartphone 1202, and the WiFi router 1201 then onboard the next devices in the network. There are now four onboarding-capable devices, and only three more SoftAP nodes to onboard (IoT Device 1204, tablet computer 1210, and IoT device 1205). According to the tree map in this particular example, it may be highly efficient for the laptop computer 1211 to onboard the IoT device 1214, which is a client-only device. It may also be most efficient for the desktop computer 1203 to onboard the IoT device 1204 (which is a SoftAP node), for the smartphone 1202 to onboard the tablet computer 1210 (which is a SoftAP node), and the Wi-Fi router 1201 to onboard the IoT device 1205 (which is a SoftAP node). At this point, all the SoftAP nodes in the network are onboarded. Also at this point, all of the SoftAP nodes are available to onboard other devices, as listed at the fourth level 1264. Additionally, the fourth level also lists the one client device that has been onboarded so far, which is IoT device 1214.
At the fourth level 1264, there are only client devices left to be onboarded, and there are more than enough SoftAP nodes to onboard each one. According to the tree map in this example, it may be most efficient for the IoT device 1204 to onboard the IoT device 1207, for the tablet computer 1210 to onboard the IoT device 1208, for the IoT device 1205 to onboard the IoT device 1212, for the desktop computer 1203 to onboard the IoT device 1206, for the smartphone 1202 to onboard the IoT device 1209, and for the laptop computer 1211 to onboard the IoT device 1212. The onboarding of these devices is shown at the fifth level 1265. The IoT device 1214 at the fourth level 1263 does not onboard any other device because it does not have a SoftAP, and the Wi-Fi router 1201 at the fourth level 1263 does not onboard any devices because there are no other devices to onboard, and the Wi-Fi router 1201 may have been the least efficient option for onboarding each of the client devices.
In the example described, if the onboarding of each device takes approximately one minute, the onboarding of all the devices may be accomplished within four levels, or four minutes (given that the first device, the Wi-Fi router, is already onboarded to begin with). An advantage to this distributed bulk onboarding method is that all devices can be onboarded more quickly than by having each device onboard through one device such as a Wi-Fi router (e.g., thirteen devices might take thirteen minutes).
As stated earlier, an aspect of the disclosure is that when one device onboards another, the onboarding device provides the SSID, security credentials, some other possible network credentials, as well as the tree information that allows the onboardee device to know which, if any, other devices it must onboard. In some embodiments, the tree information may exist as a complete map of all the devices in the network and may indicate which devices will onboard which other devices, and at which level of stage that onboarding will take place. For example, all the information in

It will be appreciated that data store (e.g., memory 1408) described herein can be either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. By way of illustration, and not limitation, nonvolatile memory can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable PROM (EEPROM), or flash memory. Volatile memory can include random access memory (RAM), which acts as external cache memory.

Memory 1408 of the subject systems and methods may comprise, without being limited to, these and any other suitable types of memory.
Communications device 1400 can further include distributed bus module 1430 to facilitate establishing connections with other devices, such as communications device 1400. Distributed bus module 1430 may further comprise bus node module 1432 to assist distributed bus module 1430 managing communications between multiple devices. In one aspect, a bus node module 1432 may further include object naming module 1434 to assist bus node module 1432 in communicating with endpoint applications 1410 associated with other devices. Still further, distributed bus module 1430 may include endpoint module 1436 to assist local endpoints in communicating with other local endpoints and/or endpoints accessible on other devices through an established distributed bus. In another aspect, distributed bus module 1430 may facilitate inter-device and/or intra-device communications over multiple available transports (e.g., Bluetooth, UNIX domain-sockets, TCP/IP, Wi-Fi, etc.).
Additionally, in one embodiment, communications device 1400 may include a user interface 1440, which may include one or more input mechanisms 1442 for generating inputs into communications device 1400, and one or more output mechanisms 1444 for generating information for consumption by the user of the communications device 1400. For example, input mechanism 1442 may include a mechanism such as a key or keyboard, a mouse, a touch-screen display, a microphone, etc. Further, for example, output mechanism 1444 may include a display, an audio speaker, a haptic feedback mechanism, a Personal Area Network (PAN) transceiver etc. In the illustrated aspects, the output mechanism 1444 may include an audio speaker operable to render media content in an audio form, a display operable to render media content in an image or video format and/or timed metadata in a textual or visual form, or other suitable output mechanisms. However, in one embodiment, a headless communications device 1400 may not include certain input mechanisms 1442 and/or output mechanisms 1444 because headless devices generally refer to computer systems or device that have been configured to operate without a monitor, keyboard, and/or mouse.
