Betting on Challenges for Flourishing Ambient Intelligence

Dr. Rosa Iglesias, Ikerlan Technological Research (Mondragón, Spain)
This talk will present a brief overview of systems, technologies and applications that are part of Ambient Intelligence (AmI). It is also the purpose of this talk to bring together researchers for inspiring innovation in the evolution of AmI and for answering the question: What are the challenges we need to bet on?

JTP: An Energy-conscious Transport Protocol for Ad Hoc Networks

Dr. Alberto Medina, Internetwork Research Group, BBN Technologies (Cambridge, England, United Kingdom)
JTP: An Energy-conscious Transport Protocol for Ad Hoc Networks Energy consciousness is percolating rapidly through all areas of research for technologies that are power driven. In the context of networking, the area of ad hoc networks has been the main driving factor pushing energy-related research, with significant efforts pursued mainly at the physical, data-link and routing layers of the protocol stack.

An Algebraic Approach to Internet Routing

Prof. Dr. Tim Griffin, University of Cambridge
A great deal of of interesting work was done in the 1970s in generalizing shortest path algorithms to a wide class of semirings also called "path algebras" or "dioids". Although the evolution of Internet Routing protocols does not seem to have taken much inspiration from this work, recent "reverse engineering" efforts have demonstrated that an algebraic approach is very useful for both understanding existing protocols and for exploring the design space of future Internet routing protocols. This course is intended teach participants the basic concepts needed to understand this approach. No previous background will be assumed.

Innovating the Multi-Provider Internet

Prof. Dr. Sergey Gorinsky, Assistant Professor at the Applied Research Laboratory in the Department of Computer Science and Engineering at Washington University in St. Louis, USA.
With the Internet offering a single best-effort service, there have been numerous proposals of diversified network services that align better with the divergent needs of different distributed applications. The failure of these innovative architectures to gain wide deployment is primarily due to economic and legacy issues, rather than technical shortcomings. We propose a new paradigm for network service differentiation where design principles account explicitly for the multiplicity of Internet service providers and users as well as their economic interests in environments with partly deployed new services. Our key idea is to base the service differentiation on performance itself, rather than price.

Optimization, Pricing and Control in Networks

Prof. Dr. Fernando Paganini, Universidad ORT, Uruguay.
In the last decade, a new theoretical foundation for quantitative network research has emerged. Its key ingredients are the following: economic models to formulate network resource allocation as a convex optimization problem; use of optimization methods to devise decentralized solutions to these problems, in terms of dynamic adaptation of the relevant variables; tools of control theory to understand the dynamic properties of these methods. The resulting body of theory has been highly successful in providing models for TCP congestion control, describing how local protocols should be designed to allow for interesting global properties to emerge. From here, recent research has advanced this methodology to other layers of the protocol stack. In this course we will provide an introduction to this interdisciplinary field of research.

From Networking Research to Hapto-Virtual Multimedia Communications

Prof. Dr. Nicolas Georganas, Life Fellow IEEE; Cátedra de Excelencia, University Carlos III of Madrid (Spain); Visiting Researcher IMDEA Networks (Madrid, Spain), and Distinguished University Professor University of Ottawa (Canada)
Multimedia Communications, involving traditional “media” such as audio, video, text, 2D graphics, have become parts of everyday e-life. New digital media, such as Virtual Reality and Haptics, have now added new dimensions to multimedia tele-collaboration. This presentation will introduce basic issues on Distributed and Collaborative Virtual Environments, where the feeling of “touch” (haptics) and its transmission over networks is becoming essential. Various applications will be described ranging from industrial training to e-commerce to medical education, and the current research at the DISCOVER research lab, Univ. of Ottawa will be outlined.

Key Issues of Peer-to-Peer Mechanisms as Future Internet Communications

Prof. Dr. Ralf Steinmetz, Full Professor at the Department of Electrical Engineering and Information Technology; Department of Computer Science of the Darmstadt University of Technology (Germany); President of the Board of Trustees at IMDEA Networks
Ralf Steinmetz is one of the world experts in multimedia and P2P applications, is the author of one of the most referenced books in the area, and he has received the ACM Multimedia Award. Since early 1996 Ralf Steinmetz has been a professor at the dept. of Electrical Engineering and Information Technology as well as at the dept. of Computer Science of the Darmstadt University of Technology, Germany. There he is in charge of a chair position as managing director of the "Multimedia Communications Lab". From late 1996 until late 2001 he directed the GMD/Fraunhofer Integrated Publications and Information Institute. In 1999 he founded the Hessian Telemedia Technology Competence Center (httc e.V.). On whose board he has since served as chair. He is also one of the directors of the Information Transfer Office at the university. From 2002 to 2004 as dean he managed the department.
