Mobility Management for Target Tracking in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are broadly used in many applications including surveillance. There are many approaches of target tracking in WSN. Generally sensor node needs to move to different location to keep track of signal-emitting target. Time of Arrival with respect to signal is the measurement employed to make mobile sensor moving decisions. Recently Xu et al. proposed a mechanism for target tracking and mobile sensor navigation. Their approach is known as a min-max approximation approach that can effectively estimation the location of tracking using a concept known as semidefinite programming relaxation. They also proposed weighted tracking algorithm to achieve target tracking with accuracy. In this paper we implement target tracking mechanism that leverages the effectiveness of WSN in terms of packet delivery ratio, throughput, and delay performance. The simulations results reveal that the proposed approach is useful in accurate target tracking in secure fashion.
