CASA is a research group of laboratory IRISA, Université Bretagne Sud.
The research activity of team CASA aims at supporting communication and service provision in mobile networks that operate by exploiting transient radio contacts between mobile devices. Such networks are usually referred to as opportunistic networks in the literature although the terms delay-tolerant and
disruption-tolerant networks (DTNs) are sometimes used instead.
Part of our activity consists in studying routing protocols for opportunistic networks, namely by implementing these protocols in communication middleware so they can be tested in real conditions. We also investigate how distributed applications can be designed so as to perform satisfactorily in such networks.
The term Opportunistic Computing has been introduced in the literature in order to refer to a new computing paradigm that relies exclusively on such pairwise contacts. 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 opportunistic networks.
