A policy reasoning architecture for cognitive radio networks

Cognitive radio networking is a technology aiming to improve wireless spectrum utilization. The classical concept of spectrum owning license by different stakeholders is not valid in cognitive environments, where radios can dynamically access the spectrum. The dynamic spectrum access by cognitive radio devices requires abandoning the current concept of preprogrammed policies. Rather than that, it yields more flexible and dynamic policy system in order to opportunistically use the temporary unused spectrum holes. This paper advocates a policy based system in cognitive radio environments and proposes a novel policy reasoning architecture that can be used for policing a cognitive radio network.
