Abstract :
In this paper, a preemptive priority queueing model is developed to describe the traffic behavior of secondary users in cognitive radio systems. As the performance measures, the system dwelling time for non-real-time traffic and the blocking and forced termination probabilities for real-time traffic are derived.
