基于树形拓扑的无线Mesh网络路由协议研究

研究和分析了无线Mesh网络路由协议及其特点,提出了无线Mesh网络路由协议设计原则.遵循这些原则,充分利用Mesh网络全相连的优点构建出树形逻辑拓扑结构,该拓扑结构能满足无线Mesh网络业务特点的要求.在该拓扑树基础上设计了一种基于树形拓扑的无线Mesh网络路由协议(TTRP),该协议采用无开销的源地址学习方式构建路由相关表项,快速链路切换和路由重定向机制大大提高了TTRP路由协议的健壮性和网络的抗毁性.网络仿真结果表明了该路由协议的可行性.

Research on tree topology-based routing protocol in wireless mesh network

A routing protocol of wireless mesh networks are mainly researched,analyze wireless mesh networks' characteristic is analyzed and the principle of design of routing protocol is brought forward in this network.Based On the principle and taken full advantage of wireless mesh network's full-connected link,a tree logistic topology which can meet the need of this network's characteristic of traffic is constructed.Based on the tree logistic topology,a new routing protocol for wireless mesh network called tree topology-based routing protocol(TTRP) is presented.This protocol adopts source address learning way which is no overhead to build routing interrelated table.Fast link switch and routing redirection policy improve the TTRP' robustness and network's invulnerability.Results of network simulation show that this protocol is feasible.
