摘　　要：LEACH协议是第一个在无线传感器网络中提出的分簇路由协议,由于其簇头产生的随机性,产生了一些不足,因此为了均衡整个网络的能耗,延长WSN的生命周期,提出了基于节点剩余能量和节点度的多跳分簇路由协议。其基本思想是在LEACH中加入门限,让剩余能量高且节点度高的节点优先成为簇头,簇头之间采用多跳路由传输机制。仿真结果表明,该协议能够有效地延长网络的生命期。Low energy adaptive clustering hierarchy （LEACH）algorithm is the first clustering routing protocol in wireless sensor networks. Due to the random election of cluster head in LEACH, there are some deficiencies. So in order to balance the energy consumption and to extend the life cycle of WSN, multi-hops clustering routing protocol which is based on the node residual energy and node degree is proposed. It participates in threshold in LEACH in order to choose the node which has higher energy and higher node degree as the cluster head, and adapt cluster heads multi-hops routing transmission mechanism. The simulation results show that the improved protocol can effectively prolong the network lifetime.
