摘　　要：为保证无线传感器网络(WSNs)的连通性,延长网络有效工作期,提出了一种事件驱动成簇、能量高效均衡的路由协议。该协议避免了与事件无关的节点参与成簇而消耗能量,通过簇首选举的控制消息延时转发节省了网络能量,建立了综合考虑当前节点剩余能量和包含其邻居节点的平均剩余能量、当前节点到邻居节点和Sink节点距离的中继路由法则。仿真结果表明:与采用预成簇的AEEC协议和事件驱动成簇的ARPEES协议相比,所提出的路由协议推迟了首个死亡节点的出现时间,使WSNs有效工作期分别提高了4.3倍和47%。To ensure connectivity of wireless sensor networks （WSNs） and extend effective working time of networks, a new routing protocol with efficient and balanced energy based on event-driven clusters is proposed. The protocol cut energy consumption produced by nodes unrelated to the event participating cluster, and save network energy by delayed transmission of the controlled information Of the cluster head election, establish relay routing rule with a comprehensive consideration of residual energy of the current nodes including average residual energy of neighbor nodes, and distance from current node to neighbor nodes and Sink nodes. Simulation results show that, compared with the pre-clustering AEEC and event-driven clustering ARPEES protocols, the proposed routing protocol prolongs the time of the first death node and thus increases effective working time of the WSNs by 43 times and 47 % respectively.
