AODV与DSDV路由协议性能仿真与比较

文章首先介绍了自组网的概念和特点以及表驱动与源驱动两类路由协议，然后概述了这两类协议中比较经典的AODV和DSDV路由协议。为了对这两种路由协议的性能进行比较，使用了NS-2网络仿真软件，仿真时选取了分组平均递交率、端到端的平均时延、平均跳数和归一化的路由协议开销这四个衡量指标对AODV与DSDV路由协议进行了性能评估，并通过改变业务源连接数目、节点的移动速度和业务源的发包率等参数分析比较了这些参数对这两个协议性能的影响，仿真结果表明AODV适合于中小规模，业务源发包率较低的场合，DSDV适合于网络规模小且节点移动速度较低的场合。文章的最后对全文进行了总结。

Simulation and Comparison of the Performance of AODV and DSDV Protocols

First the paper introduces the concep of the Ad hoc network and its characteristic and the table - driven and the source - driven protocols , then summarizes the AODV and DSDV route protocols which are typical route algorithms. In order to compare the performance of the two routing protocols, the simulation soft tool NS -2 is used and the average packet delivering rate, end - to - end delay, mean hops and the normalized routing load are chosen to evaluate the performance of the AODV and DSDV. Then the effects of these parameters on the performance arc analyzed and compared by changing the cbr connection numbers, the mobile speed of the node and cbr sending packet interval. The simulation result indicates that the AODV is suitable to small and middle scale and lower sending packet interval and the DSDV is suitable to small scale and lower node mobile speed.
