Wireless sensor networks(WSNs)have received more and more attention on the object tracking system,but the performance of active routing is low. In this paper,we present an novel energy efficient dynamic target tracking (EE-DTT) protocol for wireless sensor network, EE-DTT has three obvious features: Firstly, it improves virtual grid ideas to divide each cluster into MxN square area and select a working node in each grid to reduce redundant information and economize energy. Secondly, EE-DTT improves energy utility by changing the activity of wireless communication module of sensor nodes, energy model and state transition of sensor nodes. last,it adopts initiative optimization method to optimize routing. Simulation results show that,compared with AODV and TSR, EE-DTT significantly reduce in energy consumption and prolong the network lifetime.
