Abstract: | This paper explores analytical Radio Resource Management models where the relationship between users and services is mapped
through utility functions. Compared to other applications of these models to networking, we focus in particular on specific
aspects of multimedia systems with adaptive traffic, and propose a novel framework for describing and investigating dynamic
allocation of resources in wireless networks. In doing so, we also consider economic aspects, such as the financial needs
of the provider and the users’ reaction to prices. As an example of how our analytical tool can be used, in this paper we
compare different classes of RRM strategies, e.g., Best Effort vs. Guaranteed Performance, for which we explore the relationships
between Radio Resource Allocation, pricing, provider’s revenue, network capacity and users’ satisfaction. Finally, we present
a discussion about Economic Admission Control, which can be applied in Best Effort scenarios to further improve the performance.
Part of this work has been presented at the conference ACM/IEEE MSWiM 2004, Venice (Italy).
Leonardo Badia received a Laurea degree (with honors) in electrical engineering and a Ph.D. in information engineering from the University
of Ferrara, Italy, in 2000 and 2004, respectively. He was a Research Fellow at the University of Ferrara from 2001 to 2006.
During these years, he also had collaborations with the University of Padova, Italy, and Wireless@KTH, Royal Institute of
Technology, Stockholm, Sweden. In 2006, he joined the “Institutions Markets Technologies” (IMT) Institute for Advanced Studies,
Lucca, Italy, where he is currently a Research Fellow. His research interests include wireless ad hoc and mesh networks, analysis
of transmission protocols, optimization tools and economic models applied to radio resource management.
Michele Zorzi received a Laurea degree and a Ph.D. in electrical engineering from the University of Padova in 1990 and 1994, respectively.
During academic year 1992–1993, he was on leave at UCSD, attending graduate courses and doing research on multiple access
in mobile radio networks. In 1993 he joined the faculty of the Dipartimento di Elettronica e Informazione, Politecnico di
Milano, Italy. After spending three years with the Center for Wireless Communications at UCSD, in 1998 he joined the School
of Engineering of the University of Ferrara, Italy, where he became a professor in 2000. Since November 2003 he has been on
the faculty at the Information Engineering Department of the University of Padova. His present research interests include
performance evaluation in mobile communications systems, random access in mobile radio networks, ad hoc and sensor networks,
energy constrained communications protocols, and broadband wireless access. He was Editor-In-Chief of IEEE Wireless Communications,
2003–2005, and currently serves on the Editorial Boards of IEEE Transactions on Communications, IEEE Transactions on Wireless
Communications, Wiley’s Journal of Wireless Communications and Mobile Computing, and ACM/URSI/Kluwer Journal of Wireless Networks,
and on the Steering Committee of the IEEE Transactions on Mobile Computing. He has also been a Guest Editor of special issues
in IEEE Personal Communications (Energy Management in Personal Communications Systems) and IEEE Journal on Selected Areas
in Communications (Multimedia Network Radios). |
