Context

We are developping middleware and software tools that make it easier to use mobile ad hoc networks, or more precisely mobile pieces of equipments that offer communication support and that can thus cooperate. We put the stress on robustness, security and adaptability.

Example target hardware are: mobile phones; RFIDs; smart cards; PDAs; sensors, etc. Example target networks are: DTN, mobile ad hoc networks; etc.

It is the case that in some if not all of our applications and supporting software components, location awareness is an important feature. Therefore Global Navigation Satellite Systems (GNSS) are among the technologies that we are studying and working with. More precisely we have considered its current most effective implementation, GPS, even though we are interested in the promising GALILEO system.

We are currently working on a number of different equipments :

Contributions

  1. A GPS interface on mobile phones (NMEA, J2ME)

    The work that has been achieved consisted in implementing the JSR-179 (Location API for J2ME) on a laptop and on a mobile phone (Sony Ericsson P910i). We have implemented this API plus a number of extensions, among which the possibility to handle different input sources for the location information stream (Bluettoth, file, etc.), and the possibility to handle different location protocols (currently only the NMEA component has been developped, but the software is ready for other protocols).

    A user interface has also been developped.

  2. Integration of a GPS location system within a sensor network (Xbow, Mica2, TinyOS) application

    We consider applications the goal of which is to collect local on the field data samples that are thereafter assembled to build a global view of a phenomenon (temperature, radioactive cloud tracking, etc.). Location awareness is used not only to localize the samples but it is also useful to elaborate replacement values for lost samples (for instance by interpolation over a given geographical area).

    This application is achieved in collaboration with the DGA and is partly funded by a PhD grant. It is also supported by the Sarah ANR project.
