Role of Game Theory in Utilizing the Spectrum in Cognitive Radio Networks

Abstract

Cognitive radio technology, a significant communication paradigm, enhances the efficient use of existing wireless spectrum resources and has become a prominent research topic in recent years. Game theory can play a pivotal role in dynamic spectrum allocation because it is very useful in designing and analyzing the systems where an interactive process exists and decision making is required. It is important to note that in cognitive radio networks (CRN) users need to adapt their operating parameters to the dynamic environment where they have different priorities, hence classical or static approaches do not optimally utilize the spectrum. In past, game theory has already been applied to CRN with success. In this paper a descriptive strategy for efficient utilization of licensed spectrum by the users of unlicensed spectrum using the principles of game theory is proposed. It has been observed that utilization of game theory can help in efficient utilization of spectrum while maintaining good QoS.
