Supply function equilibrium pricing strategy for primary user prioritized dynamic spectrum access

In dynamic spectrum access network, primary users have the priority of spectrum usage and the spectrum demands by secondary users are time changing. In this paper, we propose to model the primary user prioritized spectrum access as a supply function equilibrium (SFE) game, and then we present the pricing strategy by maximizing the revenue of primary users. Primary users collect the information of spectrum demands from secondary users, and calculate the price using their own spectrum supply. Numerical analysis are proposed to evaluate the performance of the proposed spectrum management mechanism.
