摘要
在Ad Hoc网络中,如何针对实际的应用选择一个最佳的路由协议是一个难点问题。分析DSDV,OLSR,DSR,TORA和AODV五种常用的Ad Hoc路由协议,基于网络节点暂停时间及最大移动速度变化两种情况,设计了针对平均端到端时延、数据包分组传送率、路由开销和平均跳数四个指标的仿真实验。仿真结果表明:在相同的网络环境下,与其他四种协议相比,OLSR协议的平均时延、路由开销和平均跳数都较小,分组传送率也较高,性能最好。通过对五种协议性能指标的综合比较,提出了一个通用的路由选择方案。
In Ad Hoc network,how to choose optimal rooting protocol according to the actual application is a hard work. Five common used Ad Hoc routing protocols including DSDV, OLSR, DSR, TORA and AODV are analysed. In the case that the pause time and maximum moving speed of the nodes changed in network, simulation experiments of which the indexes and average end -to- end delay, packet delivery ratio, routing overhead and average hops are designed. Simulation results show that comparing with the other four protocols in the same network, the average delay, routing overhead and average hops of OLSR is less, packet delivery ratio is higher, and the performance of it is the best. After comparing the performance indexes of the five protocols, an universal scheme of routing choice is proposed.
