Abstract:
This paper addresses the class of wireless sensor networks where the nodes are using batteries as power sources. It describes the adaptation of an existing analytical battery model to fit the constraints of the wireless sensors in terms of available resources, the algorithm complexity being reduced to O(n) in case of constant loads. The analytical battery model obtained is used together with another existing battery model to provide real time information about the remaining capacity of the battery, based on the electric current draw and elapsed time. The current consumption is estimated using application specific power profiles, thus the monitoring solution proposed does not imply additional hardware on a mote and can be used on each node of a WSN during network employment as a real time decision support.
