Game Theoretic Approach to Spectrum Resource Sharing and Pricing in Cooperative Cognitive Radio Networks

Abstract

The current game models for Cognitive Radio (CR) networks, such as auction mechanisms and noncooperative games are always used separately and independently, which complies with the simple onelayer dynamic spectrum access (DSA) scenario well.However, integrated game models which jointly consider the negotiation and cooperation between the primary users (Pus) and second users (SUs), and the benefits of individual PUs and SUs in the newly emerged relaying based CR networks has been very rare.The design of the integrated game model has to consider the specific features of the intra-layer competition and the cross-layer negotiation in the new CR scenarios, simultaneously.The layered and cross-layered DSA schemes and related scheduling algorithms research will provide the achievement and outcomes for cooperative relaying and overlay based CR networks.The advantage of the new merging technology which combines cooperative relaying and CR is superior to the pure spectrum-transfer based CR technology nowadays in terms of QoS support and high spectrum and energy efficiency.
