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.
Based on hierarchical network structure and scale-free network, a single-hop-multi-hop routing protocol is proposed to build energy-efficient wireless sensor network. This protocol is based on the criterion of “maximum degree of aggregation” and “Average shortest path ” characteristic, in order to reduce the propagation cost effectively.On the intra-cluster data routing approach, the single-hop-multi-hop routing algorithm is adopted to effectively reduce the local node energy failure.According to the simulation experiment, The validity and feasibility of the protocol and algorithm are verified, and compared with the existing typical protocols, the protocol shows some advantages in terms of system function, system energy consumption and reliability.At the same time, the effective balance of network energy and network life The effective extension of the period has also been verified.The protocol can better meet the resource constrained wireless intelligent network monitoring system requirements.
