摘要 针对无线传感器网络中传感器能量有限的问题,从路由算法的角度出发,提出LEACH协议的低功耗改进方案。本文采用划定区域的方式对LEACH协议中的簇头选举进行改进,从而减少网络中节点分布不均匀的情况对簇头节点能量损耗所造成的影响,并使用NS-2进行协议改进前后的仿真。仿真实验结果表明,协议改进后网络生存期有效增长,能量消耗降低,性能优于原LEACH协议。 Aiming at the problem of limited energy of sensors in Wireless Sensor Networks（WSN）,this paper proposes an approach of energy-saving improving for LEACH protocol in aspect of routing. To alleviate the adverse effect on the energy consumption of the clustering head, resulting from the nonuniform distribution of nodes in network, this paper adopts the methods of cluster-head selection based on zone, and compares LEACH protocol with the original one by using a simulation software NS-2. Simulation by NS2 shows that the protocol extends the survival time of the network , has lower energy consumption and performs better than the original LEACH protocol.
