基于改进OLSR路由协议mesh网络的研究

Research of Mesh Network Based on the Improved OLSR Routing Protocol

该文针对无线mesh网络性能需求及目前所面临的挑战,研究了先应式的链路状态路由协议OLSR,指出了该协议在选择多点中继集合时可能使某些节点负载过重,导致网络拥塞。提出了一种改进的多点中继集选择算法,高效地实现控制消息在网络中的洪泛,在此基础上,基于改进的OLSR路由协议组建了具有多跳自组织的mesh网络,通过布置实际节点验证了改进的OLSR协议在网络的吞吐量、网络延时等方面都得到了一定的改善,提高了网络的性能。

For wireless mesh network performance requirements and the challenges facing at present,this paper describes the proactive optimized link state routing（OLSR） protocol,points out that the protocol may make some nodes overloaded in selecting multipoint relays（MPR） set,this leads to network congestion.Then the paper presents an improved MPR set selection algorithm to achieve an efficient mechanism for flooding control traffic,on this basis,based on the improvement of the DSR routing protocol has formed a multiple hops selforganizing mesh network,by the layout of the actual node to verify the improved OLSR protocol has been some improvement in the throughput of the network,the network delay,improve the performance of the network.
