提出了基于一跳邻居节点集合的能耗均衡多跳分簇路由协议NS-MCRP.网络初始化阶段,基站计算若干个簇头节点以及所有节点的一跳邻居节点集合,并广播簇头信息和所有节点的一跳邻居集合.在网络运行过程中,所有节点根据簇头节点的位置信息来划分自己的一跳邻居节点集合,并从一跳邻居节点集合中选择剩余能量最大的节点作为下一跳节点.簇头节点推举本簇内部最大剩余能量的节点作为下一轮的簇头节点.实验结果显示,与Leach协议相比较,NS-MCRP协议具有更好的能耗均衡特性,网络生命时间得到延长.
One-hop neighbor set based multi-hop distributed clustering routing protocol(NS-MCRP) is proposed.In the initial stage,BS(base station) computes the cluster heads and the nodes′ neighbor sets,and broadcasts the cluster heads information as well as the neighbor sets in the network.When the network is running,the one-hop neighbor set of a node is divided by the node according to the node′s position and the positions of the one-hop neighbor nodes and the cluster heads′ positions.The one-hop neighbor node with the maximum residual energy is elected as the next hop of the node.The node with the maximum residual energy is elected as the cluster head of the next round by the cluster head of this round.The simulation results show that compared with Leach,NS-MCRP improved the energy consumption balance property of the network and prolongs the network lifetime.
