Game Theoretic Channel Selection for Opportunistic Spectrum Access With Unknown Prior Information
The authors investigate the problem of distributed channel selection in an Opportunistic Spectrum Access (OSA) system, from a game theoretic perspective. They consider a practical scenario where the channel availability statistics and the number of secondary users are unknown. They formulate the problem of distributed channel selection as a repeated game and prove it to be an exact potential game. Since, there is no prior information about the channel availability statistics and there is no information exchange between secondary users, then existing approaches are not feasible in the game.
