Abstract
In this paper, we study the distributed multichannel spectrum sharing problem for the cognitive radio networks (CRNs). We are interested in dynamic spectrum sharing schemes that maximize the spectrum utilization of the cognitive network while appropriately protecting primary users. Existence and optimality of the Nash Equilibrium (N.E.) are investigated. Distributed Multichannel Spectrum Sharing (MCSS) algorithm is proposed to approach the optimal N.E. Simulation results are obtained to verify the validity of the proposed algorithm.
