摘　　要：针对被动式单播路由协议AODV-UU、DSR-UU和DYMOUM,使用OMNeT++(Objective Modular Network Testbed in C++)仿真软件,选取分组投递率、平均端到端时延和路由发现频率3个指标对AODV-UU、DSR-UU和DYMOUM路由协议进行了性能仿真,通过改变节点数目和节点移动速度分析比较了这些参数对3个协议性能的影响,仿真结果表明:DYMOUM协议在平均端到端时延和路由发现频率上优于AODV-UU和DSR-UU,但在分组投递率上低于AODV-UU和DSR-UU.最后提出了对DYMOUM协议的改进.Aiming at passive unieast routing protocol AODV-UU, DSR-UU and DYMOUM, we use the simulation soft tool OMNet ＋ ＋ （ Objective Modular Network Testbed in C ＋ ＋ ） and choose the packet delivery ratio, average end-to-end delay and route discovery frequency to evaluate the performance of AODV-UU, DSR-UU and DYMOUM. We change the speed and numbers of the nodes to analyze and compare the effects of different parameters. The results show that DYMOUM is better than AODV-UU and DSR-UU at average end-to-end delay and route discovery frequency, but is lower in packet delivery ratio. In the end, we propose the improvements in DYMOUM.
