Routing protocol in multi-channel wireless mesh networks
Ling Liu · Journal of Computer Applications · 2011
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.
