A Survey on Target Tracking Techniques in Wireless Sensor Network.

Wireless Sensor technology is rapidly spreading all around the world. One important use of sensor networks is the tracking of a mobile target (point source) by the network.Mobile target tracking in wireless sensor networks has gained a lot of attention in the recent years due to the special characteristics of these WSNs. Considering the wide application of tracking WSNs, varied issues of data aggregation, scheduling, routing and energy conservation have been revisited and new solutions have been projected recently. Due to the importance of this topic, a detailed survey becomes necessary and helpful. In this paper we present a survey of the progressive mobile target tracking techniques in WSNs and the target tracking techniques available so far in wireless sensor networks.
