Abstract	We propose 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, each available frequency channel is assigned to a primary user who may independently lease the channel to secondary users. Secondary users are allowed to transmit in multiple channels simultaneously. We establish conditions for the system to reach an equilibrium and analyze the robustness of the proposed game theoretic D-DSL in time-varying channels. For the same amount of available primary spectrum, D-DSL leads to better overall performance compared to previously proposed Centralized-DSL.
