摘　　要：In this paper, we focus on the target tracking problem in sensor networks and propose an Power-saving target localization scheme （PSTL） based on a conjec- ture model that reflects the moving pattern ofa target, and also a corresponding two-step communication protocol be- tween Base station （BS） and sensors. BS executes a query mechanism to determine which sensors should be used for detailed information according to a limited amount of data received from sensors. This scheme reduces both energy consumption and communication bandwidth requirement, prolongs the lifetime of the wireless sensor networks. Simulation results indicate that it can achieve a high accuracy while saving a large amount of energy.
