An Improved Power Control Algorithm in Cognitive Radio Networks 
Based on Game Theory

Abstract

Abstract:

Abstract: Based on the noncooperative power control game created by David Goodman, we propose a new sigmoid efficiency function and an improved pricing function suitable for Cognitive Radio Network (CRN). This pricing function considers the fairness among users, and the existence of the Nash Equilibrium (NE) is proved. Simulation results show that the proposed power control game not only enhances the network throughput, reduces emission power of cognitive users and improves the utility, but also takes into account the system fairness to some extent than other previous schemes.
