DBTA Workshop on Mobile Information: Architectures and Technologies

7 September 2007
EPF Lausanne
Location: EPFL, INM200

The goal of this workshop is to provide a general introduction to the topic of mobile information systens and the issues that they raise in information systems.


Mobile Phones: A Revolution in the Payment Industry?
Dr. Jan Ondrus, University of Lausanne
Mobile phones are seen by many as potential devices for paying purchases. So far, only few countries in Asia were able to implement rather successful schemes. Besides technical issues, stakeholders have troubles designing profitable business cases. The objective of the talk is to expose the current issues and lessons learned about the Swiss market.

In-Network Information Management
Dr. Philippe Cudre-Mauroux, EPFL
Future information systems will operate on data acquired in real time by collections of sensor networks and RFID antennas. Several projects from the National Center of Competence in Research in Mobile Information and Communication Systems (NCCR-MICS) aim at supporting end-to-end information management for sensor and mobile networks. This talk gives an overview of several research efforts related to data acquisition, data storage and data integration in large-scale and decentralized communication systems. We discuss protocols and data management middleware for sensor networks and processes to manage continuous streams of data. Also, we address issues in information processing across different networks, in particular bridging several sensor networks developed independently or bridging sensor networks with the current Internet.

A Conceptual View on Trajectories
Dr. Christelle Vangenot, EPFL
Analysis of trajectory data is the key to a growing number of applications aiming at global understanding and management of complex phenomena that involve moving objects (e.g. worldwide courier distribution, city traffic management, bird migration monitoring). Current DBMS support for such data is limited to the ability to store and query raw movement (i.e. the spatio-temporal position of an object). This presentation explores how conceptual modeling could provide applications with direct support of trajectories as a first class concept. A specific concern is to allow enriching trajectories with semantic annotations allowing users to attach semantic data to specific parts of the trajectory.

User-Defined Geo-Localised Information: the present and the future
Prof. Dimitri Konstantas, University of Geneva
The high resolution of new the geo-localisation technologies and their integration into consumer mobile devices (mobile phones, pdas etc), combined with the availability of high bandwidth networks, will create new opportunities for services and applications managing geo-localised information. The main question however is where the content will come from. We expect that services allowing the users to create and exchange the geo-localised content will become very popular in the near future, providing the vast majority of content for Location Based Services. In this presentation we present what can done today and what are some perspectives for the future.

Semantic Service Composition for Information Access in Mobile Environments - the CASCOM Approach
Prof. Heiko Schuldt, University of Basel
Mobile information access is becoming more and more important in a large variety of application domains. An example is healthcare and especially emergency assistance, where the ubiquitous access to relevant patient data is crucial and can even be life saving. In most cases, data is made available by means of dedicated services. Thus, providing mobile information access requires i.) the discovery of service types based on their semantics, ii.) the proper composition of services according to the user's needs, iii.) the location of service instances, iv.) distributed execution and control of composite services, and iv.) appropriate failure handling mechanisms to provide dedicated execution guarantees. An infrastructure that combines these characteristics has been developed in the context of the EU-funded project CASCOM. One of the main foci of the project is support for both patients and physicians in emergency assistance. This talk presents the CASCOM approach that seamlessly combines mobile computing, Semantic Web Services, context-awareness, and agent technology for highly dynamic distributed service environments.
