Executive Summary

Cognitive radio networks provide the capability to share the wireless channel with licensed (primary) users in an opportunistic manner. Primary users have a license to operate in a certain spectrum band; their access can only be controlled by the primary operator and is not affected by any other unlicensed (secondary) user. On the other hand, Secondary Users (SUs) have no spectrum license, and they attempt to exploit the spectral gaps left free by primary users. This paper studies the spectrum access problem in cognitive radio networks from a game theoretical perspective.
