A novel spectrum allocation scheme in a centralized scenario with the support of multi-transceiver structure of CMR (Cognitive Mesh Router) in CogMesh network is proposed. Traditional MR (Mesh Router) in WMN (Wireless Mesh Network) is no longer met the demand of the development of wireless communication in the field of dynamically utilizing vacant spectrum holes. Therefore, MR is reconstructed into CMR with a multi-transceiver structure. CMR inherits some good merits from MR and add some special function, such as learning, aggregation, allocation and etc., to better adapt to dynamic spectrum scenario. In the paper, CMR can use the proposed SASMS to allocate vacant spectrum bands for SMCs (Secondary Mesh Client), which access the CMR with one hop.
