OVERVIEW: The past few years have witnessed the emergence of Peer-to-Peer (P2P) systems as a means to further facilitate the formation of communities of interest over the Internet in all areas of human life including technical/research, cultural, political, social, entertainment, etc. P2P technologies involve data storage, discovery and retrieval, overlay networks and application-level routing, security and reputation, measurements and management. This tutorial will give an appreciation of the issues and state of the art in Peer-to-Peer Networking. It will introduce the underlying concepts, present existing architectures, highlight the design requirements, discuss the research issues, compare existing approaches, and illustrate the concepts through case studies. The ultimate objective is to provide the tutorial attendees with an in-depth understanding of the issues inherent to the design, deployment and operation of large-scale P2P systems.

OVERVIEW: Small and portable devices all capable of wireless computing & networking increasingly populate the world. Seamless integration of people, devices, appliances and computation is expected to become an essential part of daily life, influencing individuals, families, schools and organizations of all kinds. Networks will be pervasive, ubiquitous, multi-service, multi-operator and multi-access. They will bring together several different types of networks, such as body area networks (BAN), vehicular area networks (VAN), personal area networks (PAN), home area networks (HAN), wireless hotspot networks, and cellular networks among many others. Mobile workers are now requiring personalized multimedia services at different locations on the networks. Locations that a user may visit can be configured into a private network in which users can expect to retain seamless access to services provided by their home network as they move from one location to another with automatic service adaptation supported by context aware infrastructures. This tutorial will review the state of
the art in context awareness technologies and applications, with
specific focus on context aware devices and systems. Then it will
describe the use of context information to help achieve user mobility
prediction and policy based QoS adaptation in mobile communications. The
concept of Ambient Networks will be introduced as well as their
architecture, functional areas with a focus on how context information
can be deployed to augment and enhance the operations and management of
Ambient Network. Finally the tutorial will discuss how mobile agent
technology, policy management and context awareness can be combined to
develop and deploy mobile services and infrastructures for context aware
multimedia applications. BIOGRAPHY: Ahmed Karmouch received his MS
and Ph.D. degrees in computer science from the University of Paul
Sabatier, Toulouse, France, in 1976 and 1979 respectively. From 1976 to
1983, he was a Research Engineer at INRIA (Institut National de
Recherche en Informatique et en Automatique) Paris, France. First in
distributed databases with the Sirius Project, and then with the Kayak
Project where he researched Office Information Systems and was
responsible for the Multimedia Distributed Message System Research
Group. From 1984 to 1988 he was with Bull SA, Paris, France, as a Senior
Manager at the Department of Advanced Studies. He was responsible for
the Distributed Multimedia Document Management Group. From 1988 to 1991,
he was Director of research on Multimedia Distributed Databases and
Architectures at the Ottawa Medical Communications Research Group,
University of Ottawa. Since 1991 Dr. Karmouch has been Professor of
Electrical and Computer Engineering and computer Science at the School
of Information Technology and Engineering, University of Ottawa. He also
holds an Industrial Research Chair from the Ottawa Carleton Research
Institute and Natural Sciences and Engineering Research Council. He has
been Director of the Ottawa Carleton Institute for Electrical and
Computer Engineering. Dr. Karmouch is involved in several projects with
Telecommunications Research Institute of Ontario, Nortel Networks, Bell
Canada, Mitel, Ericsson Canada, National Research Council Canada, Centre
National de Recherche Scientique in France, March Networks, CANARIE,
Communications & Information Technology Ontario (Cito), and TeleLearning
National Center of Excellence. Dr. Karmouch is a partner in the
“Wireless World Initiative: Ambient Networks”, a European Sixth
Framework Integrated Project. His current research interests are in
distributed multimedia systems and communications, mobile computing,
home architecture and services, context aware ad hoc communications,
Ambient Networks and mobile software agents for Telecommunications. Dr.
Karmouch has published over 190 papers in the area of multimedia
systems, mobile communications and mobile agents for Telecommunications,
he is member of ACM and IEEE, he has served in several program
committees, organized several conferences and workshops, edited several
books and served as Guest Editor for IEEE Communications Magazine,
Computer Communications, MTAP, and others.
OVERVIEW: This half day tutorial provides a technical overview of the architecture, components and protocols of the emerging 3GPP IP Multimedia Subsystem (IMS) / 3 GPP2 Multimedia Domain (MMD) which provides the technological basis for the provision of mobile multimedia services within converging mobile packet networks (e.g. GPRS, UMTS, WLAN, WiMax, etc.). This tutorial introduces the driving forces for the IMS architecture, provides an overview of relevant standard bodies looking at IMS (e.g. 3GPP, 3GPP2, ETSI TISPAN, OMA, etc.) and explains the key IMS elements and protocols. Special attention will be given to the IMS application server options, namely CAMEL, OSA/Parlay and SIP AS and the implementation of IMS services, such as Push to Talk, community-based services and converged applications. The tutorial ends with an overview of the FOKUS IMS play ground (www.fokus.fraunhofer.de/ims). The seminar is structured into the following parts 1. Overview of 3G Services and
Architecture 2. IMS standards and main principles 3. 3GPP IMS Application Server options 4. IMS Applications 5. Summary BIOGRAPHY: Thomas Magedanz (PhD) is professor in the electrical engineering and computer sciences faculty at the Technical University of Berlin, Germany, leading the chair for next generation networks. In addition, he is director of the “3G beyond” division at Fraunhofer Institute FOKUS, which also provides the national 3G beyond test and development centre in Germany. He is senior member of the IEEE, editorial board member of several journals, and the author of more than 120 technical papers/articles. He is the author of two books on IN standards and IN evolution. Based on his 15 years of experience in the teaching complex IT and telecommunication technologies to different customer segments in an easy to digest way, Dr. Thomas Magedanz is a globally recognised technology coach. His employments as university professor and division head of a major German R&D organisation make him a prime choice for such trainings, as he is able to provide a non-biased presentation of the technologies. He regularly provides strategic and technology briefings for major operators and telecom vendors, as well he acts often as invited tutorial speaker at major telecom conferences and workshops around the world. Peter Weik studied "Industrial Engineering and Management Science" at the University of Karlsruhe, Germany with specific emphasis on Telematics and Telecommunication networks. He did his diploma thesis at the Fraunhofer Institute for Open Communication Systems (FOKUS) in the field of Next Generation AAA infrastructures and joined the team "Next Generation Network Infrastructures" of Prof. Dr. Thomas Magedanz in 2004 as a PhD student. He is actively involved in the realisation of the Open IMS Playground and in various national and international research projects. His field of interest is "Identity Management solutions for NGNs". |
