Topology Control Algorithm Target Tracking-Oriented

Target tracking in wireless sensor networks with limited recourses is a challenging problem. Thus, deployment of sensor nodes must focus on power conservation. It is possible to extend the lifetime of a network by controlling its topology through clustering. Topology control target tracking-oriented in wireless sensor network is proposed in this paper. When a target move to the sensing filed, cluster heads is located by fuzzy clustering, and then these cluster heads invite their neighboring sensors to form a cluster. The trajectory of targets is estimated by maximum entropy clustering. Utilizing cluster technology can make good use of each sensor nodes´ limited energy and perform tasks coordinately.
