Thursday, 09:00 – 10:30, G.73: Session I [EU Cluster Day]
ID: 105 Title: The BETSY project on timeliness and energy aspects of wireless video streaming Authors: M. Sénéclauze, J-D Decotignie (CSEM), P. van der Stok, H. de Groot, M. van Hartskamp, G. van Doren, D. van Heesch, C. Otero Perez (PR), M Joosten (C-lab), C. Blanch, J. Bormans (IMEC), M. Geilen, T. Basten, B. Theelen (TU/e), C. Koulamas, G. Papadopoulos, A. Prayati (ISI), G. Fohler. D. Isović (MDH), G. A. Papadopoulos, P. Cheng, Z Abraham (UCy) Affiliation: see above Project: IST-BETSY [www.hitech-projects.com/euprojects/betsy] Email: peter.van.der.stok@philips.com Abstract: The BETSY project focuses on the seamless adaptation of multimedia streams on wireless hand-held devices to fluctuating network conditions and available terminal resources. Consequently, the user can enjoy true multimedia experiences with freedom of movement in a networked home or at any hot-spot. A stream model is developed during the project to optimize the energy consumption and satisfy the timeliness constraints and optimize the energy consumption. The project is in its first 8 months. The initial stream model that is the basis of further work is described and motivated.
ID: 99 Title: Using TinyOS Components for the Design of an Adaptive Ubiquitous System Authors: Omer Sinan Kaya, Ozlem Durmaz Incel, Stefan Dulman, Roland Gemesi, Pierre Jansen, Paul Havinga Affiliation: The Department of Computer Science, University of Twente, PO-Box 217, 7500 AE Enschede, The Netherlands Projects: IST-EYES [www.eyes.eu.org] Smart Surroundings [http://smart-surroundings.org] STW-PROGRESS Featherlight Email: {o.s.kaya, durmazo, dulman, gemesir, jansen, havinga}@cs.utwente.nl Abstract: This work is an initiative attempt toward component-based software engineering in ubiquitous computing systems. Software components cooperate in a distributed manner to meet a demand, and adapt their software bindings during run-time depending on the context information. There are two main research topics investigated in this study. The first topic is how to build an architecture, consisting of software components, that supports adaptation and self-configuration. We explain why that component is needed, what the requirements are and how it will be designed. Besides component-based design, we build our architecture on top of Publish/Subscribe (P/S) model. We like to reuse the TinyOS components and as a second topic, we investigate the problems that will be experienced when converting these components to our P/S oriented environment. Our experiences during this research pointed out that; buffer exchange and flexible interface name representation are not suitable for ubiquitous systems.
ID: 100 Title: Wireless Sensor Networks and Beyond: A Case Study on Transport and Logistics Authors: L. Evers, M. J. J. Bijl, M. Marin-Perianu, R. Marin-Perianu, P. J. M. Havinga Affiliation: The Department of Computer Science, University of Twente, PO-Box 217, 7500 AE Enschede, The Netherlands Projects: IST-EYES [www.eyes.eu.org] Smart Surroundings [http://smart-surroundings.org] Email: l.evers, m.marinperianu, r.s.marinperianu, p.j.m.havinga }@ewi.utwente.nl; m.j.j.bijl@student.utwente.nl Abstract: Wireless Sensor Networks provide opportunities even outside their usual application domain of environmental monitoring. In this paper we present a case study on the use of Wireless Sensor Networks for the control and management of transport and logistics processes. In this study nodes will track all activities, and check for errors that might occur in the process of handling and distributing goods. The nodes will be programmed to warn when errors occur, and keep an activity record of the entire process. An overview of the current situation, and the errors that occur therein, is given. A system architecture is described that can solve or reduce the current problems by incorporating a Wireless Sensor Network in the process.

ID: 101 Title: Link and system-level analysis of structured multi-hop networks Authors: M. J. Hart and S. K. Vadgama Affiliation: Fujitsu Laboratories of Europe Ltd, Hayes Park Central, Hayes, UK UB4 8FE Project: IST-ROMANTIK [www.ist-romantik.org] Email: Mike.Hart@uk.fujitsu.com Abstract: The IST-ROMANTIK project focussed on resource management and advanced receiver architectures for multi-hop networks, running from February 2002 for 3 years. A modified UMTS HSDPA system level simulator incorporating relaying nodes was used to confirm gains predicted from a link level analysis of the propagation loss enhancement associated with the use of multi-hop techniques. This paper provides a brief overview of the link level propagation analysis developed within the project. Whilst the link level interference analysis is not presented in this paper, system level simulation results are presented. In particular these indicate that for two specific deployment scenarios a significant increase in coverage, especially at the cell edge, as well as a capacity gain was achievable. However, these gains were shown to be dependent on both careful positioning of the relays and optimal setting of the transmit power.
ID: 106 Title: A simple architecture for a Wireless DVI UWB radio link Authors: Domenico Porcino Affiliation: Philips Research Laboratories - Wireless Group, Cross Oak Lane, Redhill, Surrey RH1 5HA, England Project: IST-PULSERS [www.pulsers.net] Email: domenico.porcino@philips.com Abstract: not available at moment of publication
ID: 107 Title: Overview of Ultra-wideband (UWB) Regulatory Processes Authors: Walter Hirt Affiliation: IBM Research GmbH, Switzerland Project: IST-PULSERS [www.pulsers.net] Email: hir@zurich.ibm.com Abstract: not available at moment of publication
