Title: Scheduling Techniques, Access Schemes and Mobile Internet Protocols for Wireless Communication Systems

Abstract: Aim of this course is to provide a survey on radio resource management techniques for satellite systems also considering the characteristics of terrestrial cellular and wireless systems in the aim of an integrated network. A survey on QoS requirements, traffic classes, and traffic models will be provided since these aspects are instrumental to resource management issues. Moreover, analytical methods will be described that are based on queuing theory. Finally, suitable basic characteristics of mobile Internet and satellite IP networks will be surveyed.

1. General Concepts on Radio Resource Management

• Introduction on satellite communication systems
• Orbital options and architectures
• Traffic flows:
− Classes
− Characteristics
− QoS requirements
• Survey on physical constraints such as round trip delays and channel issues
• Introduction to resource management
− Survey on the resource space of DVB−S2/−RCS (layers 1 and 2)
− Survey on the resource space of S−UMTS (layers 1 and 2)

2. RRM Techniques

• Scheduling schemes:
− Weighted Fair Queuing (WFQ), Earliest Deadline First (EDF), Idealized Wireless Fair Queuing (IWFQ), Proportional Fair (PF), PF with Exponential Rule (PF−ER)
− Scheduling example for Satellite−HSDPA
• Access protocols: Aloha−based, PRMA−based, DAMA, S−RACH
• Cross−layer methods: interactions between layer 2 and other layers.

3. RRM in Hybrid and Wireless Networks

• Hybrid wireless and satellite systems (GEO and non−GEO): scenarios and examples
• WCDMA
• WiFi (IEEE 802.11e)
• WiMAX (IEEE 802.16d, IEEE 802.16e)

4. Analytical Methods for RRM

• Markov Chains
• M/G/1 theory
• EPA analysis
• Application example: performance evaluation and stability analysis

5. Models for Traffic Generation

• Short−range dependent traffic models
− MMPP
• Long−range dependent traffic models
− Pareto-based

6. Mobile Internet Protocols

• Satellite IP networks (BSM architecture)
• Mobile−IP
• PEP issues

7. Test

Lecturer’s Short Bio

Giovanni Giambene was born in Florence, Italy, in 1966. He received the Dr. Ing. degree in Electronics from the University of Florence, Italy, in 1993 and the Ph.D. degree in Telecommunications and Informatics from the University of Florence, Italy, in 1997. From 1994 to 1997, he was with the Electronic Engineering Department of the University of Florence, Italy. From 1997 to 1998, he was with OTE of the Marconi Group, Florence, Italy, where he was involved in a GSM development program. In the same period he also contributed to the COST 252 Action research activities by studying the performance of PRMA protocols suitable for supporting voice and data transmissions in low earth orbit mobile satellite systems. In 1999 he joined the Information Engineering Department of the University of Siena, Italy, first as research associate and then as assistant professor. He teaches the advanced course of Telecommunication Networks at the University of Siena. At present, he is involved in the SatNEx network of excellence (www.satnex.org) of the FP6 programme in the satellite field, as work package leader on radio resource management techniques (ja2330) and cross-layer air interface design (ja2230). He is also vice-Chair of the COST 290 Action (www.cost290.org), entitled "Traffic and QoS Management in Wireless Multimedia Networks" (Wi-QoST). He has recently published a book entitled "Queuing Theory and Telecommunications: Networks and Applications", Springer (May 2005). His research interests include third-generation mobile communication systems, medium access control protocols, traffic scheduling algorithms, and queuing theory.
