DYNAMIC SPECTRUM ALLOCATION: FROM CONCEPTS TO RECONFIGURABILITY ENABLED IMPLEMENTATION
David Grandblaise - Klaus Moessner - Paul Leaves - Didier Bourse
This paper presents the current research effort in the field of dynamic spectrum allocation (DSA) in
the context of composite reconfigurable wireless networks. Concepts and implementation issues are
respectively addressed. Firstly, motivations and supporting mechanisms of the DSA concept are
introduced in Section 2. On this basis, some potential deployments scenarios for DSA and their
associated requirements are discussed in Section 3. The enabling technologies (software defined radio, SDR)
and regulatory policies supporting reconfigurable equipment are discussed in Sections 4 and 5 respectively.
Section 6 addresses an architecture model supporting reconfigurable systems DSA at the network level.
Finally, Section 7 discusses a potential roadmap to make DSA operations a reality.
