A game-based power control scheme for cognitive radio networks

Abstract

This paper proposes a non-cooperative Game-based Multichannel Power Control (GMPC) model and a wireless resource allocation scheme for CR networks. Considering the power constraint of primary users and secondary users, the proposed model attempt to not only maximize the network throughput but also minimize the total power consumed in a CR network with external interferences. Moreover, the theoretical analysis is conducted to prove the convergence to the Nash Equilibrium. Simulations results indicate that the proposed scheme is achieve higher throughout and consume little power in the network with external interference, compared with the existing approaches.
