Performance Analysis of a Dynamic Channel Vacation Scheme in Cognitive Radio Networks. |
Abstract | ||
---|---|---|
In order to resolve the issues of channel scarcity and low channel utilization rates in cognitive radio networks (CRNs), some researchers proposed to the idea of “secondary utilization” for the licensed channels. In “secondary utilization”, secondary users (SUs) opportunistically take advantage of unused licensed channels, thus guaranteeing the transmission performance and quality of service (QoS) of the system. Based on the channel vacation scheme, we analyze a preemptive priority queueing system with multiple synchronization working vacations. Under this discipline, we build a three-dimensional Markov process for this queueing model. Through the analysis of performance measures, we obtain the average queue length of two types of users, the mean busy period and the channel utility. Finally, by analyzing several numerical experiments, we demonstrate the effect of the parameters on the performance measures. |
