Topology Control Target Tracking-Oriented

One of the most important constraints on wireless sensor network is the low power consumption. Therefore, topology of wireless sensor network 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 based on overlapping clustering in wireless sensor network is proposed in this paper. When a target move to the sensing filed, cluster heads invite their neighboring sensors to form a cluster, the sensor information is passed on to cluster heads, where, in turn, transmit information to the base station. Utilizing cluster technology can make good use of each sensor nodespsila limited energy and perform tasks coordinately.
