L'équipe CASA concentre son actitivé sur le support de la communication et des services dans les réseaux à connectivité partielle ou intermittente, et étudie notamment le potentiel de l'approche DTN (Delay/Disruption Tolerant Networking) dans cette optique.

Domaine de recherche

(Texte en anglais)

The research activity of team CASA aims at supporting communication and service provision in challenged environments, and most notably in partially or intermittently connected mobile networks. We mostly focus on mobile ad hoc networks (MANETs), and investigate how the DTN (Delay/Disruption-Tolerant Networking) approach can help support communication and services when such networks are disconnected.

Part of our activity consists in designing opportunistic routing protocols for disconnected MANETs (D-MANETs), and implementing these protocols in communication middleware so they can be tested in real conditions.

Additionally, we investigate how distributed applications can be designed and implemented for networks whose characteristics keep changing spontaneously and unpredictably. The term Opportunistic Computing has been introduced recently in the literature in order to refer to a new computing paradigm that relies exclusively on pairwise contacts bewteen mobile hosts. Team CASA strives to contribute to the development of this computing paradigm by designing methods, models, and middleware tools that make it easier for programmers to tackle the challenges presented by application development for D-MANETs.

Research directions

  • Support for communications in Disconnected Mobile Ad Hoc NETworks (D-MANETs)
  • Communications in Disconnected Wireless Sensor Networks (D-WSN)
  • Support for distributed services in D-MANETs
  • Distributed applications for D-MANETs and trials in real conditions
  • Application fields: m-Health, tactical networking, social networks, robotics, maritime communication…
