In this paper, the authors consider multiple primary and multiple secondary users cooperative cognitive radio networks, in which the Primary Users (PUs) lease a portion of their spectrum to the Secondary Users (SUs) for some revenue and in return the SUs play as relays and help forward the data of the Pus in exchange for being granted spectrum opportunities. Both the PUs and SUs aim to maximize their own utilities. The spectrum leasing and relay selection problem is studied.
