In recent literature on traffic scheduling, the combination of the twodimensionaldiscrete-time Markov chain (DTMC) and the Markov modulated Poissonprocess (MMPP) is used to analyze the capacity of VoIP traffic in the cognitive radiosystem. The performance of the cognitive radio system solely depends on the accuracyof spectrum sensing techniques, the minimization of false alarms, and the schedulingof traffic channels. In this paper, we only emphasize the scheduling of traffic channels(i.e., traffic handling techniques for the primary user [PU] and the secondary user [SU]). We consider the following three different traffic models: the cross-layer analytical model,M/G/1(m) traffic, and the IEEE 802.16e/m scheduling approach to evaluate theperformance of the VoIP services of the cognitive radio system from the context ofblocking probability and throughput.
