CASA : The team focuses on supporting communication and services in partially or intermittently connected networks. It notably investigates the DTN (Delay/Disruption Tolerant Networking) approach as a means to reach these goals.


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. The team mostly focus on the Opportunistic Networking model, and investigate how this model can help support communication and services in challenged networks.

Part of team CASA activity consists in designing opportunistic routing protocols, and implementing these protocols in communication middleware so they can be tested in real conditions.

They also 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 develop distributed applications for opportunistic networks.
