Furthermore, there is the primary network which has an opportunity to sell the spectrum to secondary network. We assume the secondary network’s interference pricing is used to<br>protect primary network and propose a joint utility maximization of the primary and secondary with a maximum interference constraint at the primary and a transmission power threshold at the secondary transmitter. Accordingly, we devise a novel cost computation strategy which is function of primary and secondary behaviors. To formulate this method, a Stackelberg game and equilibriums are exploited. Numerical results are presented to verify the proposed scheme. The impact of different system parameters is investigated and compared through simulations. https://mjee.modares.ac.ir/article_13017_a0594936f572d14b6fde439d55dc345a.pdf
