摘要
目前,对MAODV路由协议的仿真分析通常考虑网络仅有一个多播组的情况。但是,在实际应用中网络可能存在多个多播组。为此,本文提出了基于多个多播组分析MAODV路由协议性能的方法,并利用NS-2模拟器对MAODV路由协议进行仿真,分析了多个多播组对数据递交率、控制开销、时延等性能的影响。仿真分析表明,在不同网络负载情况下,多个多播组的存在降低了MAODV路由协议的性能。
The existing simulation and performance evaluation of the MAODV （Multicast Ad-Hoc On-Demand Distance Vector）routing protocol is mainly based on a single group. However, in practical applications, there may be several multicast groups in the network. This paper puts forward an idea that the performance evaluation is based on multiple multicast groups, uses the NS-2 software to simulate the routing protocol, and analyzes the influence of PDR（Packet Delivery Ratio）, and CO（Control Overhead）, and L（Latency）. The simulation analysis shows that the existence of the multiple multicast groups decrease the performance of the MAODV protocol under different network loads.
