Abstract The current framework for radio spectrum regulation and spectrum usage is undergoing fundamental changes. In the face of scarce radio resources on the one hand and under-utilized licensed spectrum on the other hand, regulators, industry and the research community are launching initiatives towards a flexible usage of spectrum. Cognitive radios realize the dynamic usage of frequency bands on an opportunistic basis. They identify and use under-utilized spectrum in a coordinated way. Policies that enable a software defined medium access are in the focus of this paper. We discuss a step towards the realization of such cognitive radios at the example of the well-known Enhanced Distributed Channel Access of IEEE 802.11e. This channel access protocol is here specified in a machine understandable policy language, instead of lengthy textual description. Such a machine-understandable description of the protocol enables cognitive radios to operate in distributed environments according to the 802.11(e) standard.
