分析了按需组播路由协议MAODV,并且在此基础上提出了基于最优化路径(path optimized aware)算法的PA-MAODV协议,并对相关路由发现方案算法进行了描述、分析、改进,最后对PA—MAODV协议在NS2中的实现、仿真和性能分析的整个过程做了详细的阐述。并将其与MAODV,AODV协议进行了性能上的比较,通过对仿真结果的分析表明,所给出的PA—MAODV协议在延迟、数据包投递率等方面能更好地适应网络环境。
Multicast Ad Hoc on-demand vector protocol (MAODV) is investigated, based of which the PA-MAODV (path optimized aware) and the implementation of router finding are proposed, including router finding algorithm description, analysis, improvement. At the end, PA-MAODV protocol is expatiated through the process of practice, emulation, performance analysis, compared with the MAODV, AODV in delay and packet delivery ratio, it has a higher performance to be adapt to the network environment.
