摘　　要：在分层网络结构和无尺度网络特性基础上,以构建能量有效的无线传感器网络为目标,提出了单跳-多跳相结合的路由协议.该协议依据无尺度"最大聚集程度"和"平均最短路径"特性,以有效降低传播代价.在簇内数据路由方式上,采用了单跳-多跳相结合的路由算法,以有效降低局部节点能量的快速失效.通过仿真实验,验证了协议和算法的有效性和可行性,通过与现有典型协议进行比较,该协议在系统功能、系统能耗、可靠性方面体现了一定的优势.同时,网络能量的有效均衡和网络生命周期的有效延长也得到了验证.该协议能够较好地满足资源受限的无线智能网络监测系统需求.On the basis of layer-built structure and scale-free network characteristic,a novel scale-free single-multi hop routing protocol was designed to build energy-efficient wireless sensor networks.This protocol can reduce propagation cost on the basis of ＇maximum aggregate degree＇ and ＇average shortest path＇.Single-multi-hop routing algorithm was designed within the cluster to reduce the rapid failure of the local nodes.Simulating test was carried out to validate availability and feasibility of the protocol scheme.Comparing with several existing typical routing algorithms,the result indicates that this protocol has advantage no matter in system function,system energy consumption,and dependability.At the same time,it was also verified that energy load is balanced,and the lifecycle is prolonged in network.The protocol can meet the need of wireless intelligent monitoring in limited resource.
