Modeling Cooperative Communications using Game Theory: Applications for Cognitive Radios

Luis Miguel Gato Díaz, Meiby Ortiz Bouza, Jorge Torres Gómez


In this paper, we present cooperative communications as a way of increasing efficiency in the use of resources of telecommunication systems. In the special case of cognitive radio networks, the main benefits and costs regarding cooperation are analyzed, as well as security issues that might rise in such a scenario. From a game theory model, we describe the implementation of a coalitional game, where users pursue individual benefits as well as benefits for the coalition they belong. Simulation results confirm the gains achievable by means of cooperative communications, and reveal weakening performance in presence of security threats. This paper may help readers to have a more comprehensive understanding of cooperative communications based on game theory, as well as the main research trends and challenges in this area.
