Title: BATTERY USE MANAGEMENT FOR WIRELESS NETWORKS
Abstract: Redundant wireless sensor networks include a plurality of wireless sensors and a wireless data concentrator. The plurality of wireless sensors sense a parameter and transmit sensor signals representative of the parameter sensed. The wireless data concentrator receives the sensor signals and adjusts the transmission schedules of at least one of the plurality of wireless sensors based on a change in operating status of one or more of the plurality of wireless sensors.

Claims: number: 1
text: A wireless sensor network comprising:
number: 2
text: The wireless sensor network of claim 1, wherein the wireless data concentrator adjusts the transmission schedule of the at least one of the plurality of wireless sensors by increasing a transmission rate of the at least one of the plurality of wireless sensors in response to the operating status of one or more wireless sensors changing from an operative state to an inoperative state, wherein the at least one of the plurality of sensors and the one or more wireless sensors sense at least one parameter of a same region.
number: 3
text: The wireless sensor network of claim 2, wherein the same region is a region of a plurality of regions of an aircraft.
number: 4
text: The wireless sensor network of any of claims 2 and 3, wherein the wireless data concentrator increases the transmission rate of the at least one of the plurality of wireless sensors by increasing the transmission rate of the at least one of the plurality of wireless sensors so that an overall transmission rate of the plurality of wireless sensors remains substantially constant.
number: 5
text: The wireless sensor network of any of claims 1-4, wherein the wireless data concentrator detects the change in operating status of the one or more of the plurality of wireless sensors based upon the transmitted sensor signals, and wherein each of the plurality of wireless sensors includes a battery that provides power to a respective one of the plurality of wireless sensors for sensing the at least one parameter and transmitting the sensor signals.
number: 6
text: The wireless sensor network of claim 5, wherein the wireless data concentrator:
number: 7

number: 9
text: A method comprising:
number: 10
text: The method of claim 9, wherein adjusting the transmission schedule of the at least one of the plurality of wireless sensors comprises increasing a transmission rate of the at least one of the plurality of wireless sensors in response to the operating status of the one or more wireless sensors changing from an operative state to an inoperative state, wherein the at least one of the plurality of sensors and the one or more wireless sensors sense at least one parameter of a same region, and wherein the same region is a region of a plurality of regions of an aircraft.
number: 11
text: The method of claim 10, wherein increasing the transmission rate of the at least one of the plurality of wireless sensors comprises increasing the transmission rate of the at least one of the plurality of wireless sensors so that an overall transmission rate of the plurality of wireless sensors remains substantially constant.
number: 12
text: The method of claim 9, 10 or 11, further comprising detecting, using the wireless data concentrator, the change in operating status of the one or more of the plurality of wireless sensors based upon the transmitted sensor signals, and wherein each of the plurality of wireless sensors includes a battery.
number: 13
text: The method of claim 12, wherein:
number: 14
text: The method of claim 12, further comprising:
number: 15
text: The method of claim 14, further comprising:
