Yang Jin-cheng · Journal of Computer Applications · 2010
In order to optimize the multi-interface and multi-channel resource in wireless mesh network, this paper studied the single-interface multi-path routing protocol and the policy of channel allocation in single-path networks, proposed the multi-path routing protocol - AODV-MP by combining the hybrid channel allocation method, which can not only realize the parallel transmission of multi-path in the network, but also increase the entire throughput rate of the network. Through analyzing the characteristics of multi-path routing protocol and considering the interference factors Signal-to-Noise Ratio ( SNR) related to neighboring nodes, the routing metric judgment WCETTSNR was put forward, and the routing metric worked as the ratio standard for traffic distribution. The AODV-MP multi-path routing protocol had been tested on the NS2 network simulation platform and the results indicate that the proposed protocol can increase the network throughput by approximately 45% and largely decrease the network delay in the situation of heavy traffics.
