EOATR: Energy efficient object tracking by auto adjusting transmission range in wireless sensor network

In this study, we develop EOATR mechanism to track objects by auto adjusting the transmission range of sensors according to the speed of object. The proposed method not only increases the tacking accuracy but also decrease the energy consumption by reducing the number of nodes that participate. Through whole tracking process and minimizing the communication cost, thus can enhance the lifetime of the whole sensor networks. The simulation result shows that our proposed method achieves lower energy consumption and precise object tacking over exciting solutions.
