摘要 针对传统LEACH协议的不足,提出一种改进的多跳均匀分簇路由(EMR:Equal-cluster-based Multi-hop Routing)算法。EMR算法从剩余节点中随机选择候选簇头,通过候选簇头的竞选半径和节点剩余能量来确定分布相对均匀的簇头,从而完成整个无线传感器网络的簇头确定,簇头之间采用以簇头节点剩余能量和链路传输代价的权值为依据的多跳路由协议。实验仿真结果表明,EMR算法相对LEACH协议、LEACH-E协议和MTE协议更有效地节省了节点的能耗,能显著地延长网络的存活时间。 Aiming at the disadvantage of classic LEACH protocol,a new energy-efficiency WSN cluster routing protocol – Equal cluster-based Multi-hop Routing（EMR） was proposed.The cluster head candidate for EMR was selected from the rest randomly,and then the candidate was elected by its neighbor,communication range and energy-reserved,electees distributing uniformly around the WSN act as cluster-head of EMR,cluster-head communication between the cluster head is multi-hop,it is dominated by a weight about the energy-reserved and the distance among them.Simulation experiment shows that,in contrast with LEACH,LEACH-E and MTE protocol,EMR protocol can effectively reduce the energy consumption of the WSN nodes,and significantly extend the lifetime of WSN.
