Recently, advances in the fabrication and integration of sensing, communication technologies and economical deployment of large scale sensor networks which are capable of large scale target tracking, become possible.therfore, the wireless sensor networks are a fast growing and marvelous research area that has attracted considerable research attention in the recent past. The creation of large-scale sensor networks interconnencting several hundered to a few thousand sensor nodes opens-up several wide range of application and technical challenges. Sensor nodes have been deployed to play significant roles in battlefield, disaster-prone area, traffic control, habitat monitoring and intruder tracking. One of the most important application of these networks is target tracking. In this application, wireless sensor networks consisted of many sensor nodes which are used to sense, detect a target and track that target until it goes out of the monitored field. Because of the nodes have limitation of energy consumption and Existance of multiple targets in real Enviroment, Power consumption and multiple target tracking issues are of great important.
