Tutorials

Abstract

This tutorial focuses on cooperation among mobile devices with selfish behavior - in other words how would we allow our mobile phone to cooperate with others. The tutorial will focus on the basics of cooperative wireless networks and advocate for cooperative behavior by the example of energy consumption and service delivery. Furthermore the application of source and network coding in cooperative clusters - also referred to as wireless grids - will be explained by examples and small demonstrations with respect to the overall Mobimedia conference theme

In 2002 he was Adjunct Professor at the University of Ferrara, Italy giving lectures on wireless communications and conducting research on multi-hop networks. In 2005 he won the YRP award for the work on MIMO MDC and received the Young Elite Researcher Award of Denmark. Due to his "outstanding skills and devotion" he was selected to receive the NOKIA Champion Award in 2007 and 2008. His current research interests are in the areas of wireless and mobile communication networks, mobile phone programming, cross layer as well as energy efficient protocol design and cooperative networking.

Biography: Marcos Katz

Marcos Katz received the B.S. degree in Electrical Engineering from Universidad Nacional de Tucumán, Argentina in 1987, and the M.S. and Ph.D. degrees in Electrical Engineering from University of Oulu, Finland, in 1995 and 2002, respectively. He worked as a Research Engineer at Nokia Telecommunications from 1987 to 1995, designing analog circuits for high-speed PDH/SDH line interfaces. From 1995 to 2001 he was a Senior Research Engineer at Nokia Networks, Finland, where he developed multiple antenna techniques for several TDMA and CDMA research projects. In 2001-2002 he was a Research Scientist at the Centre for Wireless Communications, University of Oulu, Finland, where he concentrated on synchronization problems of CDMA networks. In years 2003-2005 Dr. Katz was the Principal Engineer at Samsung Electronics, Advanced Research Lab., Telecommunications R&D Center, Suwon, Korea. From 2006 he works as a Chief Research Scientist at VTT, the Technical Research Centre of Finland. At VTT, Dr. Katz is also responsible for the research activities in the group Cognitive and Cooperative Networks. His current research interests include synchronization, multi-antenna techniques, cooperative and cognitive techniques, as well as optical communications, all aiming at future 4G wireless communication systems. In years 2006-2007 Dr. Katz served as the vice-chair of Working Group 5 (on short-range communications) for the Wireless World Research Forum (WWRF), and in year 2008 he was elected chair of that group.

Abstract

The notion of sensor networks has already been established and many prototypes are being tested widely in the world. Although they have found their applications in several areas such as environmental monitoring, they will be more powerful to be utilized by considering "sensing" in a more general way and renaming the notion to networked sensing.

In this tutorial, we first introduce basic technologies related to networked sensing. We then elaborate sensing devices. Finally we explain how they are utilzed for a small-area sensing such as human bodies and a wider area of cities. In particular, for sensing cities, we focus on man-made phenomena of people's purchasing behaviors and walking as well as natural phenomena in urban areas.

Biography: Yoshito Tobe

Yoshito Tobe is a professor at Tokyo Denki University. After he obtained M.E. in electrical engineering from the University of Tokyo in 1986, he had been working on process-control local area networks at Toshiba Corp. until 1997. He obtained M.S.(1992) and Ph.D.(2000) from Carnegie Mellon University and Keio University, respectively. His research ranges from wireless sensor networks to urban-area networks. In 2006, he started a five-year project called OSOITE focusing on urban sensing. He serves as a chair of SIGUBI of the Information Processing Soceity of Japan and a co-chair of the steering committee of International Conference on Networked Sensing Systems (INSS). He has also served as program chairs and technical program committee members for many sensor-network- and ubiquitous-computing-related conferences including Pervasive 2009.

Biography: Masayuki Iwai

Masayuki Iwai is a project associate professor at Tokyo Denki University. He is also a researcher of OSOITE, CREST, JST. He obtained his Ph.D. in computer science from Keio University in 2004. His research interests include distributed programming middleware, real-time messaging systems, and tools for small sensor nodes.
