We consider the problem of tracking a mobile target using an energy constrained wireless sensor network. This paper develops and describes a methodology to track a mobile target that moves with varying speed and direction in a 2D plane. In this paper, we combine distance measurements from several sensors to estimate location of the target. Given that available energy in sensors is at a premium, we have proposed to reduce the number of measurements. We present a methodology to track the target using measurements from an adequate number of carefully selected sensors that measure distance and communicate to the tracker. In this paper, we present results of extensive simulations that we have carried out to test and validate the algorithms. We study through simulations how the frequency of measurements by sensors, velocity of the mobile target, the amount by which the target changes its direction of motion affect the accuracy of tracking.
