摘　　要：在LEACH协议中,活动节点的数量和簇首间通信距离是影响网络生命周期的两个重要因素。在LEACH协议的基础上设计了一种基于簇首成链的低能耗层次路由协议,该协议将网络分层成簇,簇首节点将簇内距离相近、收集信息相似的节点划分为"相似"群,群内节点按序号每次只有一个节点发送数据到簇首,减少了簇内活动节点的数量,降低了簇首负载;同时簇首间引入了链式通信。理论证明和仿真结果都表明,该算法能够均衡网络能耗,延长网络生命周期。The number of active node and the communication distance between cluster heads are two important factors influencing the network life cycle in the LEACH protocol. The paper designed a cluster-chain based low-energy con- sumption hierarchical routing protocol on the basis of LEACH protocol. The protocol layers the network into clusters, cluster head nodes divide the near nodes within the cluster which collects similar information into ＂similar＂ group, and in ＂similar＂ group only one node sends data to the cluster head according to the serial number every time, reducing the number of active nodes within the cluster and the load of cluster head. And the chain communication is introduced be- tween cluster heads. Finally, it shows that the algorithm can balance the network energy consumption and prolong the network life cycle through the theoretical proof and simulation results.
