在LEACH算法的基础上对簇头选择从节点剩余能量与节点分布位置进行了加权处理，仿真结果显示，较LEACH协议延长了网络生存时间，降低了网络总体能耗。-On the basis of the LEACH algorithm for cluster heads selection on the basis of the node residual energy and the node distribution location weighted processing, simulation results show that, the LEACH protocol extended the network survival time, reduce the network energy consumption as a whole.
