This article is based on the existing dynamic channel access strategy, proposes a cognitive MAC layer channel access strategy. First of all, from the physical layer of cognitive radio spectrum detection technology to detect the idle spectrum, provide cognitive users can access channel; Second, in the network, their cognitive users maintain a real-time update list of channel state, this strategy according to channel state list to find two cognitive users need communication overlapping channels are available, and calculate the overlapping each sum of the available channel utilization rate of the primary user; Finally choose the utilization ratio of the sum of the minimum channel for data transmission, improve the data channel available transfer time. The simulation results show that the strategy under the condition of without affecting the main user communication can make the cognitive users to make full use of the authorized spectrum, improve the network throughput.
