Matching Game-Based Power Control in Cooperative Cognitive Radio Networks

Abstract

In a cooperative cognitive radio network (CCRN), Primary Users (PUs) select Secondary Users (SUs) as cooperative relays for increasing their transmission rates while SUs gain spectrum usage opportunities for transmitting their own traffics. In this paper, we particularly focus on the problems of cooperative relays selection as well as resource allocation between multiple PUs and multiple SUs in a CCRN. We propose a matching game-based power control approach to achieve the stable matching between PUs and SUs. In addition, the conflicting interests between them can be resolved. Simulation results show the benefits of our proposed algorithms in terms of average power capacity.
