摘要 对现有的LEACH协议进行改进,在局部簇中得出簇内节点的平均能量基础上,使簇头满足一定的能量约束,建立了能量参考模型,给出了正确性与复杂性分析,并在NS2平台下对改进后的协议进行了仿真实验和分析。仿真结果表明,改进的LEACH路由协议有效地延长了无线传感器网络的生存周期,从而提高了网络性能,并对下一步改进工作作了简要介绍。 Some improvement is made for current LEACH, we get average energy of nodes in the local cluster and improve cluster head to satisfy certain energy constraint, then build an energy reference model and give analysis of correctness and complexity. At last, simulation is done on the NS2 for the improved protocol. According to the result, the improved protocol could effectively prolong survivability of wireless sensor networks and improve performance of networks.
