| 摘 要： | 针对单径路由协议不能充分利用多信道无线Mesh网络的信道资源的问题，提出了一种基于拥塞控制的并行多径路由协议PMRP。该协议将一个数据流分配到多条路径同时传输，当所有路径都发生中断时，才重新寻找路由;并采取相应的拥塞感知技术，避免拥塞节点再转发新的数据流。仿真结果证明：与无线自组网按需平面距离矢量路由协议（AODV）协议相比，PMRP在网络负载较大时，能有效地减小端到端延迟，提高数据包的成功投递率，增加网络的整体吞吐量。

| Abstract: | In order to solve the problem that channel resource cannot be fully utilized by single-path routing protocol in multi-channel wireless mesh networks, a Parallel Multi-path Routing Protocol (PMRP) based on congestion control was proposed. This protocol spread a data flow over multiple paths and only re-found new route after all routes have broken. It prevented the congested node to transmit new data flow by utilizing congestion control mechanism. The simulation results demonstrate that, compared with Ad hoc On-demand Distance Vector Routing (AODV) routing protocol, PMRP can reduce the average end to end delay, and improve the data packet delivery ratio and the network throughput effectively. |
