移动Ad Hoc网络路由协议比较与分析

Comparison and Analysis of Routing Protocols in Mobile Ad Hoc Network

移动Ad Hoc网络是一个自组织系统,是由许多无线移动主机组成的一个临时动态网络,且不依赖于任何中心化的接入点和网络基础设施.对于这样一个网络,一个有效的路由协议对于适应主体的移动性以及为可能的链路提供可行的数据传输是非常必要的.限定路由协议的因素可归为两类,即无线传输过程中的衰退作用和网络拓扑的边缘效应.现存的各种路由协议着重从不同的角度来实现各自的功能.路由协议可分为两部分,路由发现和路由维护,而路由发现是其中的关键部分.

Mobile Ad Hoc network is an autonomous system, and a temporary dynamic network that formed by a set of wireless mobile nodes without the intervention of centralized access points or any infrastructure. In such a network, it is necessary to have an effectual protocol to suit the removal of the main body and to provide possible route for the data transmission. The factors which limit the routing protocol can be divided into two parts ~ fading effect of radio propagation and edge effect of network topology. The existing routing protocols take emphasize on different functions from diverse angles. Routing protocols can fall into routing discovery and routing maintenance, in which routing discovery is the key point,
