无线mesh网中最小编码代价低时延多播路由

Minimal coding cost and low delay multicast routing of wireless mesh networks

提出了一种无线mesh网中最小网络编码代价低时延多播路由协议(MNCLDMR,minimal network coding and low delay multicast routing)。MNCLDMR的目标是选择合适的网络编码节点,最小化网络编码代价,降低网络时延。MNCLDMR主要思想是引入拓扑关键节点和网络编码关键节点的概念,以下一跳的节点是否是网络编码关键节点或拓扑关键节点作为路由判据,采用MNCLD算法构造多播树。仿真结果表明,MNCLDMR可以达到预定目标,合理形成网络编码机会,能实现最小网络编码代价低时延多播路由。

A minimal network coding cost and low delay multicast routing（MNCLDMR） of wireless mesh networks was presented. The goal of MNCLDMR was to select the appropriate network coding nodes, minimize network coding and reduce network delay. MNCLDMR protocol introduces the concept of topology key nodes and network coding key nodes, serving as the routing metric whether the next hop nodes were network coding key nodes or topology key nodes, using MNCLD algorithm construct multicast tree. Simulation results show that MNCLDMR can achieve expectation goal, form reasonable network coding opportunity and achieve minimal network coding and low delay multicast routing.
