On-line speed scaling minimizing expected energy consumption for real-time tasks, by Stephan Plassart (Polaris) – We present a Markov Decision Process (MDP) approach to compute the optimal on-line speed scaling policy to minimize the energy consumption of a processor executing a finite or infinite set of jobs with real-time constraints. The policy is computed off-line but used on-line. We provide several qualitative properties of the optimal policy: monotonicity with respect to the jobs parameters, comparison with on-line deterministic algorithms. Numerical experiments show that our proposition performs well when compared with off-line optimal solutions and out-performs on-line solutions oblivious to statistical information on the jobs.

Asymptotic Studies of Large Distributed systems with Failures by Philippe Robert (Inria, Paris) – Asymptotic Studies of Large Distributed systems with Failures The qualitative behavior of a large scale storage network of non reliable file servers is investigated. In such systems a fraction of the processing capacity can be used to duplicate files on new servers when necessary. Due to random losses, with probability 1 all files will be lost eventually if no new files are added. The main question in this context is of understanding the relation between the durability of the system and the parameters of the network: the duplication capacity, the failure rate, the duplication factor and the average load of a node. Different scalings via mean-field limits or stochastic averaging can be used to study the eventual decay of these networks. They will be reviewed and discussed. An analysis of placement algorithms will be also presented. Bâtiment IMAG (442) |

Association dans les réseaux WiFi, par Isabelle Guerin (Lyon) – Les déploiements de réseaux WiFi denses permettent à une station d’avoir le choix entre plusieurs points d’accès lors de la connexion au réseau WiFi, améliorant ainsi la couverture radio, la qualité des liens radio et facilitant la mobilité. En contrepartie, la densité des points d’accès peut générer plus d’interférences et de contention, ce qui peut amener à une baisse du débit global puisque ces points d’accès doivent partager un nombre limité de canaux. Le retour à une gestion centralisée des réseaux WiFi offre l’opportunité d’une optimisation globale de l’usage de la ressource radio et donc de réduire les problèmes soulevés lors d’un partage intensif de cette dernière.

Convergence d’algorithme de non regret, Amélie Heliou (Polaris) – Les algorithmes de non-regret sont souvent utilisés dans les jeux répétés où les joueurs ont peu d’information sur le jeu auquel ils jouent. Ces algorithmes garantissent que le regret de chaque joueur est sous-linéaire. La moyenne temporelle des stratégies choisies en suivant un algorithme de non-regret converge dans l’ensemble des équilibres corrélés. Cependant cela ne donne aucune information sur la convergence de la séquence de stratégies. Bâtiment IMAG (442) |
