Duplication avoidance for energy efficient wireless sensor networks

Energy constraint is main issue of wireless sensor networks. The duplicate transmitted packets play an important role in energy consumption of WSN. In this paper a duplication avoidance method is proposed with high coverage area and low control overheads. So just a group of nodes (not all nodes) select as transmitters and the other sensor nodes forward the received packets. To preventing energy holes creation the periodic selected transmitters are distributed uniformly. The simulation results prove the advantage of proposed method with long lifetime and good coverage.
