Present invention embodiments are related to systems, methods and computer program products for integrating supplemental sensors into a sensor network to augment the sensor network and more accurately discern conditions. In particular, the present invention embodiments periodically detect and integrate previously undetected supplemental sensors into the sensor network, read fixed and supplemental sensors of the sensor network, and when readings from one or more fixed sensors in an area vary from readings of one or more supplemental sensors in the area, then the readings are evaluated to determine a condition.
Existing sensor systems such as, for example, sensor systems on trains and buses in a mass transit system, employ a defined sensor network that provides information for operators to make inferences about how the mass transit system is operating or to evaluate the mass transit system's performance efficiency. When only one sensor in an area provides information for the area and the one sensor is inaccurately reporting a condition, it is difficult, if not impossible, to determine that the provided information is inaccurate.
In a first aspect of the invention, a method is provided for utilizing supplemental sensors to monitor conditions of an area employing a sensor network. One or more supplemental sensors may be detected external of the sensor network within the area. The one or more detected supplemental sensors may be added to the sensor network. Readings may be retrieved pertaining to the conditions of the area from the sensor network, including the detected one or more supplemental sensors and one or more first sensors. A resulting condition of the area may be determined based on the comparing. In a second aspect of the invention, a computing system is provided for monitoring conditions of an area employing a sensor network. The computing system includes, among other things, at least one processor, a network interface to allow the computing system to communicate with devices of a sensor network, and at least one memory connected with the at least one processor. The at least one processor is configured to: detect one or more supplemental sensors external of the sensor network within the area; add the one or more detected supplemental sensors to the sensor network; retrieve readings pertaining to the conditions of the area from the sensor network including the detected one or more supplemental sensors and one or more first sensors; compare the readings of the detected one or more supplemental sensors and the one or more first sensors; and determine a resulting condition of the area based on the comparing.
In a third aspect of the invention, a computer program product is provided. The computer program product includes at least one computer readable storage medium having computer readable program code embodied there with for execution on a computing device. The computer readable program code is configured to be executed by the computing device to: detect one or more supplemental sensors external of the sensor network within the area; add the one or more detected supplemental sensors to the sensor network; retrieve readings pertaining to the conditions of the area from the sensor network including the detected one or more supplemental sensors and one or more first sensors; compare the readings of the detected one or more supplemental sensors and the one or more first sensors; and determine a resulting condition of the area based on the comparing.
Generally, like reference numerals in the various figures are utilized to designate like components.
Present invention embodiments include methods, systems and computer program products for periodically detecting supplemental sensors in an area, integrating the detected supplemental sensors into an existing sensor network including one or more fixed sensors, and reading the one or more fixed sensors and one or more supplemental sensors. When the readings of any of the one or more fixed sensors in an area vary from the readings of any of the one or more supplemental sensors in the area, present invention embodiments evaluate the readings to determine a condition.

In some embodiments, owners of supplemental sensors 108 may have previously been informed that by using a network in an area, including but not limited to a Wireless Fidelity (Wi-Fi) network, they are providing authorization for their supplemental sensors to be read. In other embodiments, a user may download an application to his/her supplemental sensor 108 for communicating with computing system 104 of sensor network 102. Before downloading the application, the user may be informed that he/she is providing authorization for supplemental sensor 108 to be read. In further embodiments, other methods may be employed for owners to provide authorization for reading their supplemental sensors 108.
If, during act 504, computing system 104 determined that it is authorized to read supplemental sensor 108, then computing system 104 may add supplemental sensor 108 to sensor network 102 and may assign an area to supplemental sensor 108 (act 506).
Computer system 104 may determine an area to assign to supplemental sensor 108 based on signal strength information regarding a signal detected from supplemental sensor 108. Generally, detected supplemental sensors 108 may be assigned to an area that includes a fixed sensor 106 closest to detected supplemental sensor 108. In other embodiments, other methods may be employed to assign an area to supplemental sensor 108.
Computing system 104 may then determine whether a last detected supplemental sensor, which computing system 104 is authorized to read, has been added to sensor network 102 (act 508). If, during act 508, computing system 104 determined that the last detected supplemental sensor 108, which computing system 104 is authorized to read, has been added to sensor network 102, then computing system 104 may query any supplemental sensors 108, which are newly added to sensor network 102, for type information (act 510). The type information provides an indication of a type of sensor data which may be obtained from a corresponding supplemental sensor 108. The different types of sensor data may include, but not be limited to, temperature data, humidity data, location data, orientation data and movement data.
Computing system 104 may then retrieve readings, according to corresponding type information, for conditions from supplemental sensors 108 included in sensor network 102 and from one or more fixed sensors 106 of sensor network 102 (act 512). Based on the readings, computing system 104 may determine resulting conditions in areas that include at least one fixed sensor 106 and one or more supplemental sensors 108 (act 514).
If, during act 508, computing system 104 determines that the last newly detected supplemental sensor 108 was not yet added to sensor network 102, then computing system 104 may prepare to check whether a next newly detected supplemental sensor 108 has been authorized for the computing system 104 to read (act 516). Computing system 104 may then repeat acts 504-508.
In various embodiments, when signals from a supplemental sensor 108 in sensor network 102 have not been received for a predetermined period of time such as, for example, 15 minutes, 30 minutes for another period of time, supplemental sensor 108 may be removed from sensor network 102.
If, during act 604, a determination is made that no supplemental sensors in sensor network 102 are assigned to the area, then a condition as indicated by fixed sensor 106 assigned to the area may be reported to computing system 104 (act 606). Next, a determination may be made regarding whether there are any additional areas from which sensor information may be collected (act 608). If no additional areas exist, then the process may be completed. Otherwise, preparation for collecting sensor information from a next area may be performed (act 610) and act 604 may again be performed.
If, during act 604, a determination is made that one or more supplemental sensors 108 in sensor network 102 are assigned to the area, then a determination may be made regarding whether one or more supplemental sensors 108 are reporting a condition that conflicts with a condition reported by fixed sensor 106 assigned to the area (act 612). If the condition reported by fixed sensor 106 is determined not to conflict with the condition reported by one or more supplemental sensors 108 assigned to the area, then act 606 and 608 may again be performed.
If, during act 612 a determination is made that the condition reported by fixed sensor 106 conflicts with the condition reported by one or more supplemental sensors 108 assigned to the area, then for each reported condition a number of fixed sensors 106 and a number of supplemental sensors 108 reporting each condition may be determined (act 614). Next, the counts may be weighted (act 616) and the resulting condition reported based on weighted counts (act 618). For example, in an embodiment, fixed sensors 106 may be considered to be more reliable than supplemental sensors 108 because fixed sensors 106 may be periodically inspected to determine whether each fixed sensor 106 operates correctly, while supplemental sensors 108 may belong to multiple third parties with no information known regarding whether each supplemental sensor 108 is operating correctly. In such an embodiment, conditions reported by fixed sensors 106 may be given more weight than conditions reported by supplemental sensors 108. Thus, for example, each supplemental sensor 108 may be assigned a weight of 1, while each fixed sensor 106 may be assigned a weight of 1.3. Therefore, in this embodiment, if one supplemental sensor 108 and one fixed sensor 106 report conflicting conditions, a weighted count for supplemental sensor 108 may be 1, while a weighted count for fixed sensor 106 may be 1.3 and the conflicting condition may be resolved according to the condition reported by fixed sensor 106. Conditions reported by supplemental sensor 108, reporting the conflicting condition, may then be discarded. In other embodiments, different weights may be assigned to fixed sensors 106 and supplemental sensors 108.
In some embodiments, when all supplemental sensors 108 assigned to an area suddenly stop reporting conditions, while fixed sensor 106 assigned to the area continues to report conditions, or vice versa, supplemental sensors 108 may be considered to be reporting a condition that conflicts with a condition reported by fixed sensor 106. Such a condition may occur, for example, when fixed sensor 106 and supplemental sensors 108 are assigned to an area below deck on a ship. If the area becomes flooded, supplemental sensors 106 assigned to the area may suddenly stop reporting and false reports from a defective fixed sensor 106 may continue to be reported.
