According to FCC's ruling for white-space spectrum access, white-space devices are required to query a database to determine the spectrum availability. In this paper, the authors study the database-assisted distributed whitespace Access Point (AP) network design. They first model the cooperative and non-cooperative channel selection problems among the APs as the system-wide throughput optimization and non-cooperative AP channel selection games, respectively, and design distributed AP channel selection algorithms that achieve system optimal point and Nash equilibrium, respectively. They then propose a state-based game formulation for the distributed AP association problem of the secondary users by taking the cost of mobility into account.
