In this paper, the authors investigate the admission control problem in Cognitive Radio Networks (CRNs) from the economic viewpoint. Each Secondary User (SU) has the option of accessing the spectrum or balking on account of the trade-off between the service profit and the delay cost. In order to avoid disturbing the transmission of Primary Users (PUs), the secondary user requires detecting the presence of PUs before starting its own communication. In addition, whenever a PU appears on the working channel, the SU must halt its transmission to guarantee the communication quality of PU.
