A Multiple Channel Assignment Algorithm and Routing Protocol base on Wireless Mesh Networks

摘要

In this paper, a hybrid routing protocol TOIRP and a distributed channel assignment algorithm CLBCA of VVMN in the multi-channel environment are proposed. The tree base protocol and the traditional AODV routing protocol are integrated together to reduce delay in the routing protocol, which is proposed by HWMP.A new routing metric CETTI is used in this routing protocol, which uses a new method to quantify the interference of communication. It divided interference into two parts: inter-flow interference and intraflow interference, and it integrate the considerations of hopcount and delay. This improves the throughput of WMN. The channel assignment algorithm is divided into two parts: radioneighbor binding and channel-radio binding. This algorithm is based on the channel load and avoids the channel-dependency problem which is common in the multi-channel environment. In the same time, it increases the utilization of each channel.
