摘要
采用网络仿真软件进行网络协议开发与研究是一种经济、高效的方法。文章剖析了网络仿真器NS2的组成、结构和AODV协议工作机制。针对AODV协议只支持单径路由的缺点,提出一种改进策略,分析了改进的AODV协议的实现方法。NS2仿真实验结果表明,改进协议在端到端平均时延、分组投递率、路由发现频率和路由开销等方面有一定优势。
Adopting network simulation software for the network protocol development and research is an economical and effective way. This paper has an in-depth analysis on the composition and structure of the network simulator NS2 and the working mechanism of the AODV Protocol. Aiming at the defect that AODV Protocol only supports single path routing,hence the improvement strategy was put forward. And the implementation method for the improved AODV Protocol was analyzed. The NS2 simulation test result showed the improved protocol has some advantages in end-to-end average delay,the packet delivery ratio,route discovery frequency and routing overhead.
