In this paper, the spectrum hole prediction scheme was proposed for the cognitive radio networks usnign the primary user 's traffic pattern. Using the channel prediction, the collision probability with primary users can be reduced and the system throuthput can be improved. Simulation result shows that the proposed method can enhance the throughput and reduce the interference to the primary user below the desired threshold.
