“…However, for example, if SUs try to transmit both (relatively) time-sensitive traffic and non-time-sensitive traffic, then it is necessary for a protocol to transmit data packets having traffic with higher priority first ahead of those having traffic with lower priority. A number of protocols are proposed to transmit data packets having traffic with multiple classes of priorities in slotted multi-channel CRN [13][14][15][16][17][18]. In [13], a mixed preemptive/non-preemptive M/G/1 queueing model is proposed in CRN.…”

“…In [18], a spectrum handoff prioritization using preemptive/nonpreemptive based dynamic spectrum access is proposed. However, the protocols proposed in [13][14][15][16][17][18] consider the transmission of data packets having traffic with multiple classes of priorities in a centralized CRN environment. In a centralized environment, each SU is connected to a central controller based on a one-to-one connection forming a star topology.…”

Cognitive radio network (CRN) is developed to improve the scarce but under-utilized wireless spectrum due to rapidly developing wireless networks. This paper proposes a reservation-based MAC protocol for traffic having multiple classes of priorities in CRN. One channel called control channel is used for contention resolution between secondary users (SUs). In this protocol, an SU having data packets with different class of priorities transmits its control packet containing the priority value through the control channel. The order of access to primary channels is determined based on the priority of the data packet and the position of the non-colliding control packet. The access order determines the idle primary channel that an SU uses to transmit its data packet. In this protocol, there is no performance degradation either from SUs choosing a busy primary channel or multiple SUs choosing the same idle primary channel. Moreover, even though the SU cannot transmit its data packet because there is no idle primary channel that the SU can utilize, it can re-transmit its control packet without having concern over additional collision. Multistate Markov chain is used to analyze the throughput and performance of the proposed protocol and the analytical results show that higher priority traffic can be transmitted first ahead of the lower priority traffic. Notwithstanding the above, the maximum sum of the throughput of SUs with different classes of priorities is almost equal to the available capacity, and therefore the proposed protocol can take advantage of almost all of the available portion of primary channels.

“…A comprehensive study on several channel quality estimation metrics is presented in [17] to select the best channel for a CU transmission during spectrum handoff process. Zakaria and Rabia [18] proposed an interruption based priority queue to reduce the average handoff delay. A hybrid rule‐based priority queuing model is proposed in [19, 20] to characterise the average data delivery time for CR networks.…”

In the cognitive radio network (CRN), secondary users (SUs) compete for limited spectrum resources, so the spectrum access process of SUs can be regarded as a non-cooperative game. With enough artificial intelligence (AI), SUs can adopt certain spectrum access strategies through their learning ability, so as to improve their own benefit. Taking into account the impatience of the SUs with the waiting time to access the spectrum and the fact that the primary users (PUs) have preemptive priority to use the licensed spectrum in the CRN, this paper proposed the repairable queueing model with balking and reneging to investigate the spectrum access. Based on the utility function from an economic perspective, the relationship between the Nash equilibrium and the socially optimal spectrum access strategy of SUs was studied through the analysis of the system model. Then a reasonable spectrum pricing scheme was proposed to maximize the social benefits. Simulation results show that the proposed access mechanism can realize the consistency of Nash equilibrium strategy and social optimal strategy to maximize the benefits of the whole cognitive system.
