Energy-Efficient Target Coverage Algorithm for Wireless Sensor Networks

We consider the target coverage problem and lifetime performance of wireless sensor networks (WSNs). Traditional target coverage schemes only utilize the total energy and fixed/adjustable sensing range and have lower energy efficiency. In this paper, we propose an energy-efficient target coverage algorithm by taking into account the remaining energy and number of covered targets. Numerical results suggest that, regardless of the numbers of targets and sensors, the proposed algorithm achieves longer lifetime than traditional schemes.
