Efficient Spectrum Sharing With Autonomous Primary Users: Distributed Dynamic Spectrum Leasing (D-DSL)

In this paper, the authors introduce a new architecture for dynamic spectrum sharing called the Distributed Dynamic Spectrum Leasing (D-DSL) and a game theoretic framework for its implementation on a cognitive radio network. In D-DSL, it is assumed that each channel is assigned to a primary user who may lease the channel to secondary users. The spectrum owners can thus dynamically adjust the amount of interference they are willing to tolerate from the secondary users. On the other hand, the secondary users compete with each other in order to achieve maximum possible Quality of Service without violating the interference cap imposed by the primary users on each channel.
