Abstract
Dynamic Spectrum Access is a key capability of Cognitive Radio (CR) networks to increase the efficiency in the use of the available spectrum resources. In this respect, this paper focuses on the spectrum selection problem when a number of radio links has to be established in a CR network to support applications with different bit rate requirements. A novel strategy based on a Partially Observable Markov Decision Process (POMDP) is proposed, whose target is to maximize a reward function that refl...
