چکیده:
In the following paper a Cognitive Radio Network (CRN) is studied by means of the mathematical tool of game theory. When we are faced with a distributed CRN, it isobserved that selfishness of users will decrease the efficiency of network resource usage. Indeed, this is the selfishness of theusers dispossessing them of optimum achievable state in the network. Using a game theoretical approach, we will offer a suitable pricing method which formulates the game as apotential one and allows the users to get more of network resources as long as they pay for it. Furthermore, how thismethod functions in a simulated CRN will be shown. According to simulation results, it can be perceived that in a noncooperative environment, an ordinary network face a considerable drop in the number of convergence trials and the access of users to network resources, whereas exploiting thesuggested pricing method mitigates the negative effects of selfishness of users. Moreover, the simulation results show that there are even some parameters which are bettered using the pricing method in the network in comparison with cooperative setting
