- Abstract
To solve the user congestion problem in cognitive radio spectrum allocation process, this paper, based on the game theory spectrum allocation model, proposes an equilibrium spectrum allocation algorithm based on potential game theory to quickly reach the Nash equilibrium of the game process among cognitive users and the balanced allocation of users among multiple channels. Simulation results show that the proposed algorithm can achieve balanced allocation of cognitive users among channels, avoid excessive congestion of some channels and improve spectrum utilization. In addition, it can converge to Nash equilibrium in a short time. It can effectively improve the SIR and communication quality of the system.
