摘　　要：针对无线传感器网络协议中可靠性及能量有效性,提出能量感知的无线传感器网络可靠路由EARRP.EARRP通过本地节点选择、路径预留和路径延迟广播来减少由于路径不可达带来的重传,进而提供一个可依赖的传输环境.仿真实验表明EARRP优于在汇聚节点和感应节点之间建立有效路径的传统的方法可以有效利用节点的剩余能量和有限存储资源.同时可以均匀的分配传输路径,进而实现节能目的.A major concern in the design of WSN protocols, including those concerned with reliability, is energy efficiency. We present a novel reliable energy aware routing protocol. EARRP （Energy Aware Reliable Routing Protocol） introduces local node selection, path reservation and path request broadcasting delay to provide a reliable transmission environment to reduce retransmissions caused by unstable paths. The scheme efficiently utilizes the limited energy and available memory resources of sensor nodes. Simulation experiments show that special path request flooding, and also by distributing the traffic load more evenly in the network.
