A game-theoretical modeling framework for spectrum markets and cognitive-radio devices

This report presents a novel game-theoretical framework to model the evolution of spectrum markets that consists of multiple spectrum/network operators that provide wireless access to users. It integrates models about the channel, mobility, user preference, network operators (providers), infrastructure deployment, user distribution, and price-adaptation mechanisms. Providers aim to maximize their own profit, while clients decide based on criteria, such as the financial cost of the access, transmission rate and required transmission power. This work discusses briefly the modeling framework and a novel priceadaptation algorithm for providers. It presents how this framework can be used to instantiate a cellular-based market in a small city. Finally, it analyzes the evolution of this market under different topologies and user profiles, summarizing the main performance results.
