摘要Ad-Hoc网络具有多跳的、节点可移动的特点，其节点大多数情况下除了发送和接收数据包，还兼有路由转发功能，故其路由协议与一些传统的路由协议完全不同.论文对Ad-hoc网络以及Ad-hoc网络中的三种路由协议进行了简要介绍，通过基于linux的ubuntu13.10下的NS2仿真平台，结合平台下的工具Gawk、Setdest、Cbrgen等,对这常见的三种路由协议：DSR、AODV、DSDV进行仿真，得出三者在不同速率、不同节点数的情况下，端到端时延、吞吐量、丢包率等性能参数。并通过对仿真数据绘制性能对比曲线，通过比对得出三种协议的性能评估。68501

Title    Research on Simulation of Ad-hoc Network Routing Protocols                                               

Abstract

Ad-Hoc network is known for characters of multi-hop，and mobile nodes.In addition to sending and receiving packets, nodes in this network also function as a router to transmit packers. For this reason, there exist distinct differences between its routing protocols and the traditional.The network and three of its routing protocols are briefly introduced in this paper. Through NS2 simulation platform ,which is based on the ubuntu 13.10 under linux, and the tools such as Gawk platform, Setdest, Cbrgen etc, three of the common routing protocols,DSR, AODV,and DSDV,are simulated separately. The end-to-end delay,throughput,and packet loss rate, are recorded in scenes with different speed and number of nodes .The comparison curves are plotted based on the simulation data, and the evaluation of three protocols are presented by comparing the results.
