摘　　要：由于Ad-Hoc网络是一种无中心、自组织、动态拓扑的网络,所以何种路由协议的使用,尤为关键。使用QualNet软件对自组网按需距离矢量路由(AODV)和目的节点序列距离矢量路由(DSDV)进行了仿真,并提出了MCCR是以AODV为基础进行改进的分布式路由算法。从平均端到端延时、抖动率、吞吐量以及丢包率四个网络性能指标,对路由协议进行了性能分析,并且设置了不同的节点数目、节点移动速度以及节点的包停留时间参数,分析比较了这些参数对路由协议性能的影响。实验结果表明在AODV路由协议优于DSDV路由协议,由AODV改进的MCCR协议的网络性能表现最佳。The Ad-Hoc network is a non-central,self-organizing,dynamic-topology network,so which kind of routing protocol use is particularly critical. Qual Net software is used to simulate the on-demand distance vector routing(AODV)and the destination node sequence distance vector routing(DSDV),and MCCR is proposed to improve the distributed routing algorithm based on AODV. From the average end-to-end delay-time,jitter-rate,throughput and packet loss rate of the four network performance indicators,to analyze to the routing protocol performance,and set a different number of nodes,node movement speed and node packet retention time parameters. The effect of these parameters on the performance of the protocols is analyzed and compared. The experimental results show that the AODV routing protocol is superior to the DSDV routing protocol,and the performance of the MCCR protocol improved by AODV is the best.
