摘要
网络负载问题是移动Ad hoc路由算法的研究重点。通过设置不同发送数据频率和不同网络连接度来改变网络负载,利用NS2仿真Ad hoc路由协议分析性能参数:分组投递率、平均端到端延迟和路由开销,对不同负载下的网络性能进行研究。结果表明,在网络负载较小情况下,3种路由协议下的网络相差不大,当网络繁忙时,按需距离矢量路由协议的综合性能明显优于序列距离矢量路由协议和动态源路由协议。
The network load is the research emphasis of mobile Ad hoc routing algorithm.This paper changes network load by setting different transmission data frequencies and network connection degrees,uses NS2 to simulate the Ad hoc routing protocol,analyzes the performance parameters such as grouping delivery rate,average end-to-end delay and routing expense,studies the network performance in different loads.The results indicate that the networks difference under three kinds of route protocol isn＇t big under the states that network load is small,but when the network is busy,the integrated performance of Ad Hoc ondemand distance vector routing protocol is much better than that of destination sequeneed distance vector and dynamic source routing protocol.
