Geo-location database-assisted TV white space network reduces the need ofenergy-intensive processes (such as spectrum sensing), hence can achieve greencognitive communication effectively. The success of such a network relies on aproper business model that provides incentives for all parties involved. Inthis paper, we propose MINE GOLD (a Model of INformation markEt forGeO-Location Database), which enables databases to sell the spectruminformation to unlicensed white space devices (WSDs) for profit. Specifically,we focus on an oligopoly information market with multiple databases, and studythe interactions among databases and WSDs using a two-stage hierarchical model.In Stage I, databases compete to sell information to WSDs by optimizing theirinformation prices. In Stage II, each WSD decides whether and from whichdatabase to purchase the information, to maximize his benefit of using the TVwhite space. We first characterize how the WSDs' purchasing behaviorsdynamically evolve, and what is the equilibrium point under fixed informationprices from the databases. We then analyze how the system parameters and thedatabases' pricing decisions affect the market equilibrium, and what is theequilibrium of the database price competition. Our numerical results show that,perhaps counter-intuitively, the databases' aggregate revenue is not monotonicwith the number of databases. Moreover, numerical results show that a largedegree of positive network externality would improve the databases' revenuesand the system performance.
