Abstract
Previous work has reported on typical power consumption data for wireless sensor networks employing micro-electronics such as the Mica2 mote. This work is extended in this paper to cover power consumption in typical operational deployments of three battery powered wireless sensor network systems. Data for a Linux system based on XScale PXA270 processors, Texas Instruments eZ430 demonstrators and Arch Rock IPsensor nodes are presented. The effects of wireless communication, software functionality and processor configuration are illustrated. Conclusions are that power consumption and battery life are strongly influenced by processor capability. Minimizing wireless communications is always important while the effect of processor throttling is more complex and requires further research.
