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.

Keywords: reconfigurable wireless networks, dynamic spectrum allocation, software defined radio
