摘要
对Ad Hoc网络中两种典型的按需路由协议AODV和DSR协议进行了介绍,对两种协议的路由发现和路由维护过程进行了分析与比较。对两种路由协议在不同的运动场景中进行了比较系统的仿真研究。仿真中选取了数据包的传输率、端到端的平均时延、路由开销这三个指标对AODV和DSR路由协议进行了性能评估,并通过改变节点的个数、分组速率和节点暂停时间来分析比较这些参数的改变对这两个协议性能的影响。
Introduces the AODV and DSR route protocols which are the typical on- demand protocol in Ad Hoc network, also analyses and compares the route discovery and route maintenance process between two protocols. The two routing protocols are simulated in two different sport scenes. The packet delivering rate, end - to - end delay and the normalized routing load are chosen to evaluate the performance of the AODV and DSR. Then the effects of the number of node, the largest number of nodes connected and the rate of send packet on the performance are analysed and compared by changing the parameters of the mode.
