Abstract

The IEEE 802.16 standard family enables the convergence of fixed and mobile broadband networks through a common wide area broadband access technology and a flexible network architecture. In this paper we provide an overview of the recent IEEE 802.16e-2005 amendment, aimed at supporting user mobility, and we discuss several issues related to a proper choice of system parameters and strategies to be adopted to fully exploit the technology potential. Moreover, we propose a scheduling strategy aimed at providing a fair service to best eff ort users. The effectiveness of this proposal is shown via simulation.

A complete view of the research activity evaluation has to take not only single papers into account, especially when both theoretical and experimental activities are carried out in the framework of industrial cooperations. Let me recall the following initiatives: -Wireless Communication Laboratory, WiLab, founded by Prof. Oreste Andrisano as a result of tight cooperation between the National Council of Research (CNR), University of Bologna and CNIT (Consorzio Nazionale Interuniversitario per le Telecomunicazioni) through a synergic action among professors and researchers of the following bodies: Universities of Bologna and Ferrara, IEIIT-CNR, CNIT and Fondazione Alma Mater (Alma Mater s.r.l.). . -Co-foundation of the Multimedia Communication Laboratory (CNIT in Naples). Prof. Andrisano has been the Lab's Director for three years, since its foundation (Labnet project). The following Professors/researchers have been involved in the activity coordinated by Prof. Andrisano Professors : M.Chiani, R.Verdone, Velio Tralli, Gianluca Mazzini, Davide Dardari Researchers: Andrea Conti, Gianni Pasolini, Andrea Giorgetti, Cristina De Castro, Alberto Zanella, Barbara Masini, Alessandro Bazzi Main Collaborators: Paolo Toppan, Andrea Toppan, Fabio Mantovani, Giovanni Chiurco, Flavio Zabini, Matteo Mazzotti, Rudi Bandiera, Raffaele Soloperto, Andrea Ravaioli, Alberto Roversi, Chiara Balzanelli, Laura Toni, Cristina La Palombara, Giacomo Leonardi, Thomas Pavani MAIN TESTBEDS PRODUCED IN THE FRAMEWORK OF THE THEORETICAL/EXPERIMENTAL RESEARCH ACTIVITY (further details are available on the website www.wilab.org) 1.DVS: Digital Video System- repeater with echo canceller (Project DVBT-2006, MetaSystem). It has been tested on the Wilab measurement bench on digtal transmission systems at the University of Bologna, with remote access (telemeasurement): also oriented to the investigation of digital television/cellular systems mutual interference (800 MHz bandwidth) 2.SHINE: Mobile network simulator. It is a software platform for performance analysis and design of heterogeneous wireless networks and vehicular networks. 3.INFOMOBILITY Integrated simulator of vehicular traffic and wireless networks (Pegasus project) 4.LABORATORIES Network for Telemeasurement and E-Learning (Teledoc 2 Project). This project has been awarded by the SEEL (Supporting Excellence in E-Learning -EU) as the best 2004 project in the field of E-Learning). 5.IMMERSIVE COMMUNICATION GUIDE SYSTEM: localization and virtual guide through indoor sensor network (ViCom project). This project brought to an intense, still ongoing, collaboration of A. Conti and D. Dardari with M.I.T. 6.SMART CITY Reconfigurable network of intelligent poles (Pegasus project) at Fondazione Alma Mater. 7.SENSOR NETWORK control system- at Fondazione Alma Mater.
