摘　　要：针对无线传感器网络(WSNs)的数据传输问题,提出一种能耗均衡的层次路由协议,根据节点与Sink节点的最短跳数将网络划分为规模不同的簇,利用簇规模的不同,抵消数据转发所消耗的能量,实现整个网络的能耗均衡,利用虚拟力原理构建簇,最后提出了簇首多跳传输方法,实现簇首间能耗均衡。实验结果表明:提出的路由协议与LEACH协议相比传感器网络节点剩余能量方差降低了55.5%,大幅延长了传感器网络生存时间。A WSNs hierarchical routing protocol with energy consumption balance(HRPWEB)is proposed aiming at the problem exists in data transmission.The network is divided into clusters with different scales according to the shortest hops of nodes and Sink nodes.The energy consumed by data forwarding is offset by different cluster sizes to realize the energy consumption balance of whole network.The cluster is built by the principle of virtual force.Multi-hop transmission method is proposed to achieve energy consumption balance between the cluster heads.The experimental results show that the proposed routing protocol reduces the residual energy variance of the sensor network node by 55.5%compared with the LEACH protocol,which greatly prolongs the lifetime of the sensor network.
