SASMS: Spectrum Allocation Scheme under Multi-transceiver Structure in CogMesh Network

Xiao-tian Xiang and Qi-hui Wu

Abstract—A novel spectrum allocation scheme in a centralized scenario with the support of multi-transceiver structure of CMR (cognitive mesh router) in Cog Mesh 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. Besides, the scheme is designed according to the different spectrum scenario and constraint by the average minimum back-off delay of each SMC to guarantee the relatively small end-to-end delay and the equilibrium of each transceiver. From the simulation, the outstanding performance gain will be got inthe term of decreasing SMC's back-off delay through a theoretical approach and the Qualnet.
