摘　　要：提出一种基于自组织路由表的节能无线传感网路由协议SREP。通过节点的自组织路由表,以跳数和剩余能量作为参数实现分簇及簇头的选举,簇头采用多跳链式路由的方式将数据传送到汇聚点。仿真结果表明,该算法与LEACH算法相比可以均衡簇的分布,控制每一轮簇的数量,延长网络的生存时间,与PEGASIS算法相比可以有效降低网络传输时延。This paper proposes an energy-saving routing protocol based on self-organized routing table SREP.Based on a self-organized routing table for each sensor node,the protocol uses hop counts and remaining energy as metrics to realize clustering and cluster head selecting,and cluster head transfer messages to the sink with multi-hop routing scheme.Simulation results demonstrate that compared with LEACH algorithm,the algorithm can balance the distribution of clusters,control the number of clusters in each round,and prolong the lifetime of WSN.And it can reduce the network delay compared with PEGASIS algorithm.
