Présentation

DELYS étudie les nouveaux systèmes distribués d’un point de vue pratique et théorique. Sa recherche s’intéresse à un large spectre de systèmes répartis : le cloud et « Fog » computing, les réseaux mobiles, les systèmes dynamiques tels que les réseaux de robots, les multi-coeurs…

Ces nouveaux systèmes informatiques distribués doivent tolérer les fautes, supporter la dynamique des noeuds et leur hétérogénéité, gérer une virtualisation à plusieurs niveaux. Les algorithmes conçus pour les systèmes distribués statiques doivent être donc être repensés pour tenir compte de la nature hautement instable du système.
