In cognitive radio networks, Secondary Users (SUs) are considered as selfish spectrum users, thus how to maximize the spectrum efficiency by these selfish users becomes an endless research topic. Recent studies mostly focus on the competition analysis between SUs using economic mechanism, such as game theory and auction, but the spectrum owner can hardly increase the spectrum efficiency directly when SUs apply the distributed manner. In this paper, the authors consider the slotted uplink scenario where several SUs have data transmitted to secondary Access Point (AP) under distributed random access manner.
