Novel Policy Reasoning Architecture for Cognitive Radio Environments

Policing a wireless network is an evolving and exciting paradigm, specially emphasized with the emergence of cognitive radio networks. The possibility to manage radio resources efficiently and achieve different goals imposed by different stakeholders with dynamically changing policies in a wireless network is the main advantage of the policy based cognitive system. Moreover, the ability to express a variety of policy types for different purposes allows for high system flexibility and adaptability. This paper presents novel policy reasoning architecture for cognitive radio networks and elaborates on its functionalities and applications. Additionally, the paper provides a proof-of-concept testing of spectrum usage management feature of the architecture using USRP2 nodes. The elaborated policy framework is general enough to handle wide range of resource management issues in the wireless domain.
