ABSTRACT
No radio, even a cognitive one, is an island unto itself.
Government regulations and policy will always exist to
varying degrees regardless of cognitive radio technology
capabilities. Therefore, a world of cognitive radios will be
a world in which policy makers and radio designers will
need to share some common understanding of this
evolving technology. The Semantic Web—the ongoing
World Wide Web Consortium (W3C) initiative to
establish standards for machine-usable formal languages,
knowledge representations, and methods—offers an
avenue for creating formal specifications of radio
behaviors. Of particular relevance, the Rule Interchange
Format (RIF) working group within the W3C is
developing a standard that can accommodate exchange of
rules among systems using different rule languages,
possibly with differing formal semantics. As a motivating
example this paper considers such an approach for the
implementation of the Dynamic Frequency Selection
(DFS) behavior which avoids radio bands occupied by
active radar systems.
