The present disclosure generally relates to distributed networks, and in particular to deploying a program to a distributed network.
Power consumption is a critical factor for battery powered devices in a distributed system. In order to operate for long durations such as years without draining the battery, these devices should be operable to disable all hardware components except for a low power consuming component that is capable of allowing a processor or controller of the device to be in a low power consuming, sleep mode. This type of sleep mode is commonly referred to as deep sleep, allowing the device to operate for a long duration. Further, a real-time clock (RTC) is typically used as a low power consuming timing source, allowing the processor or controller to be in a sleep mode while the RTC functions to wake-up the processor or controller from sleep mode at a predetermined time or after a certain period of being in sleep mode.
The decision of when to enter sleep mode may be based on a timeout of an inactivity timer, with the timeout indicating that no activity has occurred during a certain time period or that no known events have triggered the processor or controller during the certain time period. Further, the sleep period is commonly defined using a static parameter when building the binary program that executes on the device. In preparing the processor or controller to enter sleep mode, the state of the memory associated with the application(s) deployed on the device must be written to a memory that is not affected by sleep mode. After the processor or controller has exited sleep mode, the state of the application(s) is restored, allowing the processor or controller to continue execution of the application(s). However, for programmable devices or other similar devices where an application or a function of an application may be deployed in a distributed system without flashing the device, a static sleep period may not be feasible.
Accordingly, there is a need for improved techniques for dynamically finding devices that may host applications based on the execution frequency of the application and the required sleep period of a device. Further, there is a need for improved techniques to tune and adapt the sleep period of a device where explicit triggers are not used. In addition, other desirable features and characteristics of the present disclosure will become apparent from the subsequent detailed description and embodiments, taken in conjunction with the accompanying figures and the foregoing technical field and background.

The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the disclosure are shown. However, this disclosure should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like numbers refer to like elements throughout.
For simplicity and illustrative purposes, the present disclosure is described by referring mainly to an exemplary embodiment thereof. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be readily apparent to one of ordinary skill in the art that the present disclosure may be practiced without limitation to these specific details. In this description, well known methods and structures have not been described in detail so as not to unnecessarily obscure the present disclosure.
This disclosure includes describing systems and methods of deploying a program to a distributed network. Further, this disclosure describes novel techniques of deploying an application and functional parts of that application on distributed nodes of a distributed network based on their sleep requirements, resulting in lower energy consumption by the distributed network. For example,
In
In the current embodiment, each distributed node 113-115 is operable to contemporaneously execute an instance of an application that is associated with the deployment of the functions 133-135 of the program 131. An instance of the application that is executed on each distributed node 113-115 obtains the corresponding function 133-135 and a run-time configuration associated with that function. The run-time configuration may include a sleep requirement for the corresponding distributed node 113-115. Each instance of the application installs the corresponding function 133-135 on the associated distributed node 113-115, including configuring a sleep pattern of a low power mode of that distributed node 113-115 based on its sleep requirement 119-121. The sleep pattern may represent a determined pattern of when and for how long a corresponding distributed node 113-115 operates in a low power mode (e.g., sleep mode, standby mode) based on its sleep requirement 119-121 and the execution pattern 117 of the function(s) 133-135 deployed on that node 113-115. In one example, the execution pattern 117 of the program 131 indicates that the program needs to be executed every minute from 9:00 a.m. to 5:00 p.m. each day and every hour outside those times. Further, the sleep requirement 119-121 indicates that the corresponding distributed node 113-115 may be in a sleep mode of operation for at most thirty minutes. Accordingly, the sleep pattern is determined to be one minute from 9:00 a.m. to 5:00 p.m. each day and thirty minutes outside those times. In another example, the execution pattern 117 of the program 131 indicates that the program needs to be executed once at the end of every calendar month such as to report a measurement reading. However, the sleep requirement 119-121 indicates that the corresponding distributed node 113-115 may be in a sleep mode of operation for a maximum of one week. Accordingly, the sleep pattern includes the corresponding distributed node 113-115 being in a one week low power mode for three or four consecutive weeks followed by one or more days of a low power mode dependent on the number of days in the month. In yet another example, the execution pattern 117 of the program 131 indicates that the program needs to be executed at specific times during the day, week, or month. Further, the sleep requirement 119-121 indicates that the corresponding distributed node 113-115 may be in a sleep mode of operation for a maximum of one year. As such, the sleep pattern is represented by the execution pattern 117 of the program 131.
Next, the program 131 is activated 141 on the set of distributed nodes 113-115 by each instance of the application activating the corresponding function 133-135 on the associated distributed node 113-115, as represented by respective blocks 143-145. While the program 131 is activated on the set of distributed nodes 113-115, at least one of the distributed nodes 113-115 acquires information associated with the execution pattern 117 of the corresponding function 133-135 so that the sleep pattern of that distributed node is adapted based on that execution pattern 117.
Furthermore, the node 101 may be a computer-implemented node that is a communication redistribution point or a communication endpoint in a network such as a computer server, a base station, a core network node, a handheld computer, a desktop computer, a laptop computer, a tablet computer, a set-top box, a television, an appliance, a medical device, or some other like terminology. Further, the node 101 may be user equipment (UE), a mobile station (MS), a terminal, a cellular phone, a cellular handset, a personal digital assistant (PDA), a smartphone, a wireless phone, an organizer, a handheld computer, a desktop computer, a laptop computer, a tablet computer, a set-top box, a television, an appliance, a game device, a medical device, a display device, a metering device, or the like. Also, the node 101 may be one or more of the distributed nodes 113-115. In addition, the node 101 may represent a virtual server.
Moreover, at least one distribution node 113-115 may be a computer-implemented node that is a communication redistribution point or a communication endpoint in a network such as a computer server, a base station, a core network node, a handheld computer, a desktop computer, a laptop computer, a tablet computer, a set-top box, a television, an appliance, a medical device, or some other like terminology. Further, at least one distribution node 113-115 may be user equipment (UE), a mobile station (MS), a terminal, a cellular phone, a cellular handset, a personal digital assistant (PDA), a smartphone, a wireless phone, an organizer, a handheld computer, a desktop computer, a laptop computer, a tablet computer, a set-top box, a television, an appliance, a game device, a medical device, a display device, a metering device, or the like. Also, at least two distribution nodes 113-115 may be each represented by different processors of a same node. In addition, at least one distribution node 113-115 may represent a virtual server.
