The main theme of this book is to exploit the economic and technical interactions between white space database, TV licensee, and white space access devices in the database-assisted spectrum sharing network. We first outline and analyze two promising business models: spectrum market and information market. Our analysis not only shows how different network entities interact with each other in both markets, but also shows how the markets dynamically evolve under different circumstances and what are the market equilibriums. Based on these analysis, we further formulate and optimize a hybrid spectrum and information market, which allows the geo-location databases to exploit the unique characteristics of licensed and unlicensed TV channels. These results can serve as an important first step towards the study of more general and large-scale database-assisted spectrum sharing network.
