摘要：The use of wireless sensor networks (WSN) in tracking applications is growing at a fast pace. In theseapplications, the sensor nodes discover, monitor and track an event or target object. A significant number of proposalsrelating the use of WSNs for target tracking have been published to date. However, they either focus on the trackingalgorithm or on the communication protocol, and none of them address the problem integrally. In this paper, acomprehensive proposal for target detection and tracking is discussed. We introduce a tracking algorithm to detect andestimate a target location. Moreover, we introduce a low-overhead routing protocol to be used along with our trackingalgorithm. The proposed algorithm has low computational complexity and has been designed considering the use of amobile sink while generating minimal delay and packet loss. We also discuss the results of the evaluation of theproposed algorithms. reduction on combinations of task sensors; and efficient search of optimal sensor motion. Theperformance of the proposed coordination strategy is illustrated by simulations.
