Abstract:
Spectrum utilization and resource allocation efficiency in Cognitive Radio networks can be significantly improved by the use of efficient spectrum etiquettes implemented by appropriate spectrum policy frameworks. In such a context, dynamic and flexible policies control the behavior of the terminals and the system as a whole and allow their efficient adaptation to the continuously varying environment conditions. Policies are expressed with the use of appropriate policy description languages that guarantee the efficient communication of the various network entities and the fulfillment of the policy frameworks’ objectives. This paper is a survey of the area of policy frameworks in Cognitive Radio networks. More specifically, the characteristics, architecture and main principles of a Generic Policy Framework, are described. Moreover, an overview of the most notable policy frameworks for Cognitive Radio systems is provided.
