摘　　要：针对目前无线传感器网络分簇路由协议存在的节点能耗不均衡的问题,提出一种基于分簇思想的能量高效的多跳路由协议(EEMR)。该协议首先基于节点临近度将网络划分成簇,采用簇首自适应轮转模式优化簇内节点通信的能量消耗,以高剩余能量短路径向心角的适应度路由算法均衡簇间通信负载和能量消耗,有效避免多跳路由中出现的能量消耗不均衡问题。仿真结果表明,EEMR协议能有效均衡网络内节点的能量消耗,显著延长无线传感器网络的生命期并提高网络能量利用率。In order to address the node energy consumption imbalance issue caused by clustering-based multi-hop routing protocol in wireless sensor networks, a novel clustering-based energy-efficient multiple-hop routing protocol（EE- MR） was proposed. Initially, the network is divided into clusters based on nodes proximity. Then,adaptive cluster-head round-robin schema is used to optimize energy consumption among nodes communication in each cluster, and fitness routing algorithm based on high residual energy-short path-radial angle for traffic load balance and energy consumption among traffic-heads is used to deal with the node energy consumption imbalance inssue occurred in multi-hop routing protocols. Simulation shows that EEMR protocol can effectively balance the energy consumption among nodes in WSN, significantly improving WSN lifetime and network utilization.
