摘　　要：针对无线传感网络(wireless sensor networks,WSNs)中节点能耗不均衡问题,提出一种能耗均衡的分簇路由算法(energy consumption balance-based clustering routing,ECBC)。在簇头选举阶段,ECBC算法利用节点剩余能量,节点位置以及邻居节点密度信息计算节点成为簇头的权值,再依据权值,对成为簇头的阈值进行修正;在簇间路由阶段,ECBC算法计算簇头与邻居簇头间的链路质量,并选择链路质量最优的簇头构建簇间路由。通过实验分析ECBC算法的能耗性能及数据传输性能,并分析汇聚节点位置对汇聚节点收集数据的性能。仿真结果表明:ECBC算法缓解了节点能耗。当汇聚节点位于检测区域中心时,汇聚节点收集的数据包数最多。Aiming at the problem of uneven energy consumption of nodes in Wireless Sensor Networks(WSNs),Energy Consumption Balance-based Clustering Routing(ECBC)is proposed.In the selection of cluster head,the weight of cluster head is calculated based on the remaining energy of the node,the location of the node,and the density of neighboring nodes.And the threshold of a cluster head is modified by the weight.In the inter-cluster routing,the quality of link between cluster head and its neighboring cluster heads are calculated with ECBC algorithm.And the cluster head with best quality of link is selected to construct the inter-cluster routing.The energy consumption performance and data transmission performance of ECBC algorithm are analyzed through experiments,and the effect location of sink node on the performance of the data collection of sink node is analyzed.The simulation results show that ECBC algorithm alleviates node energy consumption.When the sink node is located in the center of the detection area,the number of packets collected by the sink node is the largest.
