1、摘要移动AdHoc网(MANET)即早期军事研究中所称的移动分组无线网络,是以分组无线网技术为基础的互联的无线电台、计算机硬件和软件的集合。移动AdHoc网技术由于可快速配置稳定有效的动态网络而被主要用于军事,消防,安全和救援等场合,其次还被用于工业和商业应用中,同时由于其组网灵活,费用低廉而被作为蜂窝移动通信网的补充技术。本文首先简要介绍了移动AdHoc网的现状及发展前景,移动AdHoc网的基本概念,网络特点,网络体系结构_和面临的一系列问题。然后,基于移动AdHoc网的网络环境,对多种用于移动
2、AdHoc网络的路由协议进行了分析比较,采用AODV路由协议作为网络层协议,并且分别用两种不同的方式改进了传统的AODV路由算法,形成了CLAODV(CrossLayerAODVRoutingProtoe,01)路由算法和ALAR(AODVLoeationaidedRoutingProtoc01)路由算法。本文采用OPNET系统仿真工具搭建了移动AdI.-Iog网的仿真平台,在此平台的基础上,实现了AODV,CLAODV和ALAR路由算法。通过仿真比较传统的AODV路由算法和改进的AODV路由算法
3、的网络性能,验证了CLAODV和ALAR算法的可行性,为实际系统的设计和规划提供了参考算法、参考模型和参考数据。关键词:移动AdHoe网,路由协议,AODV,CLAODV,AI.AR,OPENT仿真系统。ABSTRACTThetechnologyofMobileAdHocNetworking(MANET)issomewhmsynonymouswitllMobilePacketRadioNetworkingfatermcoinedviaduringearlyand80’s、.Itistheofhar
