基于能耗均衡的WSN多跳分簇路由算法

摘要

This paper presents a Multi-hop and Clustering Routing algorithm based on Energy Optimized(EOMCR) for Wireless Sensor Network(WSN). It selects the cluster head nodes based on the energy factor and the ratio of energy consumption. Common node chooses a cluster to join in based on the composite distance. A cluster head node transports data to the other cluster head by the pattern of multi-hop routing. Experimental results show that the new algorithm prolongs the lifetime of WSN, compared with LEACH and other protocols, the duration of the stable phase is increased by 41%~146%, the number of the rounds of the MND phase is increased by 70.6%~239.7%, the total energy consumption of the network is reduced by 48.1%~62.2%, and it has higher feasibility and stability.%提出一种基于能耗均衡的无线传感器网络多跳分簇路由算法.该算法依据能量因子参数和节点能耗比来优选簇首,采用基于复合距离的入簇方式和分簇规模约束机制管理普通节点,并采用基于节点能量和地理位置的簇问多跳通信方式控制数据的稳定传输.仿真结果表明,与LEACH等协议相比,该算法能有效延长网络生存周期,稳定期的持续时间提高41％～146％,进入MND阶段的轮数提高70.6％～239.7％,网络总能耗减少48.1％～62.2％,具有较高的可行性和稳定性.
