Recently, dynamic spectrum sharing has been gaining interest as a potential solution to scarcity of available spectrum. The authors study the problem of designing a secondary spectrum trading market when there are multiple sellers and multiple buyers. First, they introduce a new optimal auction mechanism, called the Generalized Branco's Mechanism (GBM). The GBM is shown to be both incentive compatible and individually rational, and provides a basic element for the proposed spectrum trading market. Second, they assume that buyers of the spectrum are selfish and model their interaction as a non-cooperative game.
