Cognitive channel combination multi-channel MAC protocol

With the flourishing development of wideband wireless communication, wireless spectrum resource gets scarcer. But on the other hand, spectrum utilization is inefficient because of current static spectrum allocation. In the paper, channel combination technology is applied in cognitive multi-channel MAC protocol to improve the efficiency of spectrum utilization, and propose Cognitive Channel combination Multi-Channel MAC Protocol (CCC-MMAC). Base on the Bernoulli model, the saturation throughput of CCC-MMAC is analyzed. From the analytical result, CCC-MMAC can realize better saturation throughput and fairness.
