Abstract:
The broadband wireless world is moving towards the adoption of 
WiMAX (the commercial name of the IEEE 802.16 standard) as the 
standard for broadband wireless Internet access. This will open up 
a very large market for industry and operators, with a major 
impact on the way Internet access is conceived today. On the other 
hand, the emergence of innovative multimedia broadband services is 
going to impose severe Quality-of-Service (QoS) constraints on 
underlying network technologies. In this presentation, after an 
overview of the IEEE 802.16 standard, we intend to present an 
in-depth discussion of its QoS support features. We point out the 
scheduling algorithm as the critical point in QoS provisioning 
over such networks, and discuss architectural and algorithmic 
solutions for an efficient support of multimedia flows. 
Performance measurements obtained from an experimental testbed are 
also presented. The presentation concludes with a brief 
description of the key research challenges in the area, and 
provides a roadmap for the research in the field.

Bio:
Nicola Scalabrino received the Laurea (Telecommunication 
Engineering) and Master (Internet Technology)  degrees from 
University of Pisa (Italy) both in 2004. He is currently Ph.D 
student at University of Pisa cooperating both with the Institute 
of Informatic and Telematic (IIT) at Italian National Research 
Council (CNR) and CREATE-NET research center in Trento. His 
research interests include wireless networks with emphasis on 
Medium Access Control (MAC) and routing protocols for IEEE 802.16 
and IEEE 802.11 mesh networks. Actually he is working in Wireless 
Networks Laboratory (WINET) at the University of Florida in 
Gainesville, where he is spending a period as visiting scholar 
under the supervision of Dr. Yuguang "Michael" Fang.
