摘要
Cognitive radio network (CRN) is considered to be a novel network to improve the efficiency of utilising the precious natural resource: the radio electromagnetic spectrum. In this paper, we consider static game model of spectrum sharing between multiple primary users and secondary users. The spectrum dynamic pricing function of primary users and the quadratic cost function of primary users are given. The utility function is presented by pricing and cost function of primary users. Through the simulation of the static game of the primary users, the Nash equilibrium point of the price game has been found, and verified the maximum utility of the primary users at the Nash equilibrium point.
