A Coalitional Game Based Dynamic Spectrum Sensing Scheme

Abstract

. In this paper, to help cognitive users conduct fair and efficient spectrum sensing in the heterogeneous wireless environments, a coalitional game based spectrum sensing scheme is proposed. The method of calculating the basic parameters of spectrum sensing is introduced at first, and then the spectrum sensing problem is modeled as a coalitional game with non-transferable utility. A coalition is built with Pareto optimality satisfied, and its procedure is described in details. Simulation results have shown that the proposed scheme is both feasible and effective.
