Television white space (TVWS) technology is approaching the potential roll-out phase for
commercial deployment, supported by recent pilot projects being conducted globally …

This paper investigates the problem of database-assisted spectrum access in dynamic TV
white spectrum networks, in which the active user set is varying. Since there is no central …

In this paper, we investigate an oligopoly-competitive TV white space (TVWS) market, where
multiple secondary network operators compete to serve a common pool of secondary end …

In this paper, we study a broker-based TV white space market, where unlicensed white
space devices (WSDs) purchase white space spectrum from TV licensees via a third-party …

Database-assisted TV white space network is a promising paradigm of dynamic spectrum
sharing, and can effectively improve spectrum utilization and alleviate spectrum scarcity via …

A database-assisted TV white space network can achieve the goal of green cognitive
communication by effectively reducing the energy consumption in cognitive …

Geo-location database-assisted TV white space network reduces the need for energy-
intensive processes (such as spectrum sensing), and hence can achieve green cognitive …

This paper studies how to maximize a spectrum database operator's expected revenue in
sharing spectrum to secondary users, through joint pricing and admission control of …

Spectrum trading is an important aspect of television white space (TVWS) and it is driven by
the failure of spectrum sensing techniques. In spectrum trading, the primary users lease their …

We propose a hybrid spectrum and information market for database-assisted TV white space
networks, where a geo-location white space database serves as the platform for both the …
