Performance Analysis of a Dynamic Channel Vacation Scheme in Cognitive Radio Networks

Performance analysis and optimization research of multi-channel cognitive radio networks with a dynamic channel vacation scheme

“…Based on the channel vacation scheme, we analyzed a preemptive priority queueing system with multiple synchronized working vacations for cognitive radio networks (CRNs) [11]. We then built a three-dimensional Markov process for this queueing model.…”

“…We would like to consider the performance analyses of the wireless communication networks with interference or a sensing protocol. This paper is an extended version of our conference paper presented in [11] and give some new expressions for additional performance measures, such as the probability that the system is in the busy period and in the working vacation period, the individual benefit function, and the social benefit function. Specifically, in this paper, we add numerical results for some performance measures and optimization analysis to show how to set system parameters to reach the maximum social benefit.…”
