Cognitive radio network is expected to solve the spectrum scarcity by enabling unlicensed secondary users (SUs) to opportunistically utilize the licensed spectrum unused by primary users (PUs). In this paper, we propose an optimal admission control scheme which maximizes the profit while guaranteeing QoS of the PUs. The profit maximization problem is formulated as a Semi-Markov Decision Process (SMDP)...
