In this paper, a hybrid routing protocol TOIRP and a distributed channel assignment algorithm CLBCA of WMN 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 intra- flow interference, and it integrate the considerations of hop- count and delay. This improves the throughput of WMN. The channel assignment algorithm is divided into two parts: radio- neighbor 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.
