Game theory can be used to analyze cognitive radio

摘要

Cognitive radios, or those that can learn about and adapt to their environments, have been the focus of an emerging field of research in wireless communications. While you can argue that they have been with us for some time—sensing interference and moving off a channel are two examples—cognitive radios are on a path toward increased sophistication and complexity as adaptation algorithms are increasingly compiled into cognitive-radio etiquettes. These etiquettes imply significant complexity, due to the need to collect knowledge about the network, to classify and prioritize signals in the network, and to decide what's the best waveform for the user.
