Abstract
IEEE 802.22 is the first cognitive-radio-based wireless communication standard. We propose a spectrum transaction scheme for dynamic resource renting and offering (DRRO) and adaptive on demand channel contention (AODCC) in IEEE 802.22 inter-BS coexistence mechanismto achieve efficient and fair spectrum sharing. Game theory is applied to formulate and analyze the proposed spectrum sharing algorithm. We first analyze the simplest two-basestation (BS) game through a graphical method to gain insights for the solution. Then, the Nash Equilibrium of the n-BS game is derived and the utility profile at the Nash equilibrium is shown to be unique. We prove several desirable properties, including allocative efficiency, Pareto optimality, weighted max-min fairness, and weighted proportional fairness, are attainedt the Nash equilibrium. Lastly, we design a strategy-proof spectrum allocation mechanism based on the proposed spectrum sharing algorithm so that truthful strategies optimize each BS''s performance.
