Provides a set of abstractions and algorithms to build distributed applications in wide-scale, linking a wide set of entities to limited, geographically remote and potentially mobile capabilities.

Our research activities range from theoretical bounds to practical protocols and implementations for large-scale distributed dynamic systems to cope with the recent and tremendous evolution of distributed systems. Effectively we observed huge evolutions:

  • Scale shift in terms of system size, geographical spread, volume of data
  • Dynamic behavior due to versatility, mobility, connectivity patterns

These characteristics lead to a large amount of uncertainty. Mastering such uncertainty is actually our goal.


We aim at providing a wide range of applications (from content delivery networks to sensors networks, from backup systems to voice over IP, from publish-subscribe systems to genomic databases). We focus our research on two main areas: information management and dissemination. We believe such services are basic building blocks of many distributed applications in two networking contexts: Internet and wireless sensors. These two classes of applications, although exhibiting very different behaviors and constraints, clearly require scalable solutions. To achieve this ambitious goal, we need to tackle the issues both along the theoretical and practical sides of scalable distributed computing and ASAP will be organized along the following themes:
