Energy-Aware, Collaborative Tracking with Ad-Hoc Wireless Sensor Networks

Abstract

Abstract An energy aware, collaborative tracking algorithm is proposed for ad-hoc wireless sensor networks consisting of randomly distributed low-end sensors and a high-end data gathering node which is geometrically located at the center of each cluster. The collaborative tracking algorithm is implemented distributively by passing sensing and computation operations from one cluster to another. The network lifetime is maximized by choosing active sensors according to an energy-based cost function. Simulation results for both single and multiple simultaneously active sensors have also been preformed. Performance is evaluated based on both tracking error and energy consumption of the whole network. 1
