An improved multipoint relay selection strategy in optimized link state routing

对优化链路状态路由协议中多点中继选择策略加以改进。在求解中继节点集时,对源节点的一跳邻居节点中已被其他源节点选进中继节点集的节点,视其具有较高二跳节点覆盖数,并将其加入退出检测队列,以减少网络中继节点的冗余。仿真结果显示,在节点速率为1~30m/s时,改进策略能够降低网络时延1%~4%,减少网络拓扑控制分组2%~7%。

An improved multipoint relay selection strategy in optimized link state routing is proposed.When solving the relay node sets,take source node＇s one hop neighbor nodes,which have been drawn in relay node set by other source nodes,as that with a higher two hop node overlay number,and pull them into the exiting inspection queue to reduce the redundancy of relay nodes in the network.Simulation results show that,when the nodes move at a speed of1~30m/s,using the improved selection algorithm can reduce the network delay by 1%~4%,and cut down the number of network topology control group by 2%~7%.
