Abstract:
In this paper, we propose a novel approach for
constructing flexible link-layer protocols which separate their
functionality into multiple components. Our work is motivated
by the fact that link-layer protocols are usually implemented
as monolithic blocks. This approach limits the possibility of
reusing common functions in multiple protocols and also narrows the flexibility of combining existing blocks for creating
new protocols. Through flexibly interchangeable components,
the proposed architecture addresses these issues. We discuss
the design of the architecture and evaluate a prototype that
demonstrates cognitive radio functionality such as autonomous
link establishment, high-performance spectrum access and selforganized link maintenance after the unexpected arrival of a
primary user.
