Upper Confidence Bound Based Decision Making Strategies and Dynamic Spectrum Access
Wassim Jouini, Damien Ernst, Christophe Moy, Jacques Palicot · 2010
In this paper, we consider the problem of exploiting spectrum resources for a secondary user (SU) of a wireless communication network. We suggest that Upper Confidence Bound (UCB) algorithms could be useful to design decision making strategies for SUs to exploit intelligently the spectrum resources based on their past observations. The algorithms use an index that provides an optimistic estimation of the availability of the resources to the SU. The suggestion is supported by some experimental results carried out on a specific dynamic spectrum access (DSA) framework.
