Abstract

This paper proposes a cluster-based target tracking strategy for one mOving object using wireless sensor networks. The sensor field is organized in 3 hierarchal levels. 1-bit message is sent when a node detects the target. Otherwise the node stays silent. Since in wireless sensor network nodes have limited computational resources, limited storage resources, and limited battery, the code for predicting the target position should be simple, and fast to execute. The algorithm proposed is simple, fast, and utilizes aU available detection data for estimating the location of the target while conserving energy. This has the potential of increasing the network life time. Simulation results show that the strategy saves energy while estimating the location of the target with an acceptable error margin.
