Abstract
AbstractThe problem of dynamic spectrum access in cognitive radio environments is addressed using a game theoretic approach. In order to investigate the relevance of certain equilibrium concepts for this problem, two oligopoly game models – Cournot and Stackelberg – are considered. For a more realistic formulation of the game, a modified rationality paradigm is considered. Within this paradigm agents may have approaches and biases towards different equilibrium concepts. We investigate the Pareto equilibrium and a new equilibrium concept – the joint Nash-Pareto equilibrium.KeywordsCognitive radiodynamic spectrum accessjoint equilibriameta-rationalityadaptive strategies
