Dynamic Cluster Based Object Tracking Algorithm in WSN

In wireless sensor network, saving energy of sensor node for long circle life is important. In this paper, dynamic cluster based algorithm was proposed. The algorithm wake up or slept the sensing nodes though predicting the moving track of the target, reduce the number of tracking nodes to minimize network energy consumption. Selecting the optimal nodes to conduct the tracking task along the predicted moving track though the energy consumption of communication function, which guarantee load balancing and extend the network lifetime.
