反应式组播路由协议

Reactive mesh-based multicast routing protocol

介绍了Adhoc网络中基于网格的反应式组播路由协议RMMP。当网络中有数据要发送时,RMMP协议分布式地选出核心节点,由核心节点负责网格的建立和维护。发送节点无需加入组就可进行数据的传递,协议的实现也不依赖任何单播路由。通过NS2对RMMP协议进行仿真并与ODMRP协议的性能对比和分析表明,RMMP协议减少了网络中的洪泛控制信息和冗余链路,从而降低了控制开销和数据传递开销,减轻了网络中的拥塞,明显提高了数据传递的效率和网络的可扩展性。

Reactive Mesh-based Multicast routing Protocol（RMMP） was introduced. In RMMP, the core node was selected distributively and took responsible for constructing and maintaining the mesh when data packets waited to be transmitted in the network. The senders could transmit without joining the mesh structure in RMMP. The RMMP was also independent on unicast routing protocol. By simulation with NS-2, the protocol performance was analyzed and compared with ODMRP. The result manifests that the control overhead and data deliver overhead are reduced due to decreasing flooding control message and redundant path in network. The protocol alleviates the congestion, improves the data delivery efficiency and enhances the network scalability.
