摘　　要：提出半集中式能耗均衡多跳分簇协议SCPEBMT,协议将基于节点剩余能量选举簇头的算法应用到网络中,同时在簇头之间采用最短多跳路由算法.基站广播簇头信息和最短多跳路由.在建立多跳路由路径以及建立簇的过程中,充分考虑源节点与目标节点的能耗均衡,并提出能量距离的概念.实验结果显示,和Leach协议,EBCA协议,LEACH-EE协议相比,SCPEB-MT提高了网络能耗均衡性能,延长了网络生命时间.SCPEBMT protocol is proposed in this paper.The algorithm of electing cluster head based on the residual energy as well as the algorithm of multi-hop routing between the cluster head nodes is adopted by SCPEBMT.Base station is used for broadcasting the message containing the cluster head information and the shortest multi-hop routing.In the process of computing the multi-hop routing and constructing the clusters,the energy consumption balance between source node and destination node is considered and the concept of energy distance is proposed.Simulation results show that the energy consumption balance of the network is improved and the lifetime of the network is prolonged by SCPEBMT compared with Leach and EBCA and LEACH-EE.
