Abstract

A cognitive scenario similar to BSS (basic service set) in CogMesh network is considered. Traditional MR (mesh router) is reconstructed into multi-transceiver structure, which called CMR (cognitive mesh router). CMR can allocate vacant spectrum bands for SMCs (secondary mesh client), which access the CMR with one hop. Besides, ESA algorithm is proposed according to the spectrum scenario based on the average minimum back-off delay of each SMC. From the simulation, the outstanding performance gain will be got in the term of decreasing SMC´s back-off delay through a theoretical approach and Qualnet software.
