Ad Hoc移动自组网路由算法分析

移动Ad Hoc网络(MANET)是由移动节点组成的一个多跳的临时自治性网络,没有预先部署的网络基础设施,主要应用于需要临时、快速组网的场合.在Ad Hoc网络中,节点的随机移动性给网络协议的化设计带来了一定挑战.Ad Hoc网络的吞吐量很大程度上取决于路由协议算法.由于Ad Hoc网络的特殊性,其路由协议的设计与传统的具有固定基础设施的网络有很大不同.首先介绍了Ad hoc网络的特点,重点分析了几种常用的Ad Hoc网络路由协议,并对一些典型的路由协议进行了性能比较,最后得出结论.

Routing Algorithms for Ad Hoc Networks

MANET is a collection of mobile nodes forming a temporary network without a backbone infrastructure.The applications of Ad Hoc networks are in situations in which the network needs to be deployed rapidly.This flexibility introduces new challenges of developing efficient protocols for Ad Hoc networks.In Hoc networks,the throughput of the network depends largely upon the performance of the routing protocols.Based on Ad Hoc network's particularity,the routing protocols of it are different from those of fixed infrastructure networks.The features of Ad Hoc networks are firstly presented,then several typical Ad Hoc routing protocols are introduced and the performances of four protocols are analyzed and compared.Finally we draw the conclusions.
