The problem of spectrum scarcity can be effectively solved with cognitive radio technology, which can lead to the full utilization of spectrum holes. Most previous researches of cognitive radio were focus on the analysis of access performance under some special networks. In this paper, the access performance in the handoff probability and the blocking probability of secondary users is theoretically analyzed with mandatory priority queuing theory and the process of dynamic spectrum access in cognitive radio networks is emulated, which further verifies the theoretical results.
