Queueing Game for Spectrum Access in Cognitive Radio Networks

In this letter, we investigate the problem of spectrum access decision-making for the secondary users (SUs) in the cognitive radio networks. When the primary users (PUs) are absent on certain frequency bandwidth, SUs can formulate a queue and wait for the base station (BS) to serve. The queue of the SUs will be dismissed if the PU is emerging in the system. Leveraging the queueing game approaches, the decision-making process of the SUs that whether to queue or not is studied. Both individual equilibrium and social optimization strategies are derived analytically. Moreover, the optimal pricing strategy of the service provider is investigated as well. Our proposed algorithms and corresponding analysis are validated through simulation studies.
