In this chapter, the competitive interaction of radio devices dynamically accessing the spectrum is studied using tools from game theory. Depending on the scenario under consid- eration, the dynamic spectrum access (DSA) is modeled by different types of games following both a non-cooperative and a cooperative approach. In the first case, each radio device aims to selfishly maximize an individual performance metric (e.g., individual data rate), while in the second case such maximization concerns global network parameters (e.g., network sum-rate). In each case, we analyze network equilibria, which allow network designers, oper- ators, or manufactures to predict the behavior and performance of cognitive networks and/or terminals.
