Wireless communication technology has been widely applied in People's Daily life. However, limited spectrum resources and low spectrum utilization of spectrum resources shortage is proposed. In this paper, a cognitive function of backoff algorithm (CR-BOA) is raised. This algorithm depending on the degree of congestion channel adaptive adjustment the size of the backoff value .This algorithm greatly improves the performance of the network, and reduces the problems of delay caused by the spectrum resource scarcity. Finally, use the OPNET simulation software, the results show that the end-to-end delay and the packet loss rate are reduced.
