基于MANET的多路径路由协议分析与仿真

Analysis and Simulation of multi path routing protocol based on MANET

移动自组网MANET是由许多移动节点组成的无中心的、多跳的自组织网络,网络中的节点由于移动和能量耗尽可能会使得路径失效,因此传统的单路径协议效率并不高。本文介绍了自组网中最常用的AODV协议,重点对AOMDV多路径路由协议的路由机制和维护管理进行了探讨。最后使用NS2仿真软件对两种协议进行了比较,结果表明,在分组投递率和端到端延时方面,AOMDV比AODV更具优势。

Mobile ad hoc network is a multi-hop,no center,self-organizing network,it is composed of many mobile nodes,due to the mobility and energy depletion of the nodes,it will lead to the path become failure in MANET,therefore,the efficiency of traditional single path protocol is not high and not suitable for MANET.This paper introduces a commonly protocol AODV used in MANET,focus on a multi routing protocol called AOMDV which developed from AODV,the rooting mechanism and maintenance management of AOMDV are discussed. Finally we simulate and compare these two protocols with NS-2 software,the results show that AOMDV has more advantage than AODV on packet delivery ratio and end-to-end delay.
