摘要
高效的组播路由是移动自组网网络组播路由的研究热点之一。在分析MAODV协议的基础上,提出基于范围代理扩展的MAODV组播路由协议。通过使用区域范围代理管理和单播与广播结合的组播数据包,扩展范围代理MAODV协议。模拟仿真结果显示,改进后的协议减少网络开销和树重构次数、降低端到端平均时延、提高数据包投递率。
In the Mobile Ad hoc Network（MANET）, the efficiency multicast route is one of hot-study for the network multicast routers. This paper proposes a base scale agent method, which is used in the Multieast Ad hoc On-Demand Vetor（MAODV） multicast router protocol base on deeply-analyzed, expanding the protocol content. It uses the region scale agent to manage and multicast the data-packages by combining unicast with broadcast, expanding the protocol. Simulation results demonstrate SAMAODV not only can decrease network overhead and average end-to-end delay, but olso can decrease the number tree＇s reconstruct and enhance the pakects delivery ratio.
