Nowadays, the wireless sensor network (WSN) is used in many different fields and applications. Enemy tracking and wildlife habitats monitoring are the examples of target tracking by using of large number of sensor nodes. The main idea in this area is to find some usable target information such as location, speed and movement direction of the target because they must be available any time. By the way, the sensor nodes in sensor network model have a severe energy limit and cannot be recharged simply. In this paper, an efficient algorithm abbreviated EAASA is presented in order to reduce energy consumption while maintaining the quality of target tracking. The simulation results are compared to the AASA (cluster-based target tracking algorithm) algorithm and show that the proposed algorithm has been able to reduce energy consumption significantly while maintaining tracking quality. This method has increased the life time of the network and reduced the rate of loss of the target.
