摘要

在研究无线网状网络拓扑结构和业务模型特点的基础上,深入分析了适合WMN的路由协议类型,表明主动逐跳路由最适合WMN。优化链路状态路由是一种典型的主动逐跳路由协议。在OLSR路由协议的基础上,提出了一种感知链路的P-OLSR路由协议。该协议通过检测和分析节点负载、链路投递率和链路可用性,收集网络中节点间路径链路的质量评价,实现路由选择,增强网络的吞吐量,改善负载均衡。仿真结果表明,P-OLSR可以提高无线Mesh网络的分组传输速率,降低端到端平均时延。

A performance improvement of OLSR for wireless mesh networks
Based on studying the characteristics of topology and business model of wireless mesh networks, depth analysis of the suitable routing protocol type for WMN was given out which shows that proactive hop-by-hop routing is most suitable for WMN. On the basis of Optimized Link State Routing which is a typical proactive hop-by-hop routing protocol. A routing protocol P-OLSR of perceptive 1inks is proposed based on OLSR routing protocol. The protocol detects and analyzes the node load, and link delivery ratio, and link availability, and collects the quality evaluation of path links among the nodes on the network to achieve the selection of routing enhance the throughput of the network, and improve the load balance. The simulation results show that P-OLSR can improve the packet delivery rate of wireless Mesh networks and reduce the average end-to-end delay.
