一种基于mesh网络的多径路由协议

针对无线mesh网络的特点提出了一种基于源节点建立、目的节点维护的多径路由协议。该协议采用目的节点更新mesh结构的机制,能实时维护最优路径和其余多条路径,当节点移动或其他原因造成链路断开时,不需要路由修复或重建,从而降低了丢包率和端到端时延,且通过基于源节点建立路由的方式有效地减少了控制开销。仿真结果表明,该算法具有良好的性能。

A multi-path routing protocal based on wireless mesh networks

A multi-path routing protocol based on the establishment with source nodes and maintenance with destination nodes is proposed in this paper.The protocol refreshes the mesh structure with destination nodes,which provides the best route and other multiple routes.The routing repairment or reconstruction is not required when the links are disconnected by the mobile nodes or any other reasons,so it can reduce the loss package and end-to-end transmission delay.Besides,the control costs are reduced effectively by the way of establishing routes with source nodes.The simulation results show a good performance in this protocol.
