International initiatives

Associated team “MOCQUASIN” (Monte Carlo and Quasi-Monte Carlo for rare event simulation)

Participants : Pierre L'Ecuyer (Montreal, responsible for Canada), Katy Paroux, Gerardo Rubino, Bruno Tuffin (responsible for France), Samira Saggadi, Fabian Bastin, David Munger.

The goal of this team is to develop efficient Monte Carlo methods to compute integrals, sums or to solve equations or optimization problems. They are unavoidable tools in areas such as finance, electronics, sismology, computer science, engineering, physics, transport, biloy, social sciences... Nonetheless, the numerical methods available to tackle these problems have the reputation of being slow: they usually require a large computational time to reach a given precision. The goal of the project is to work on acceleration techniques, meaning to reach faster the targeted precision. The typical framework is that of rare event simulation for which getting even only one occurence of the event could require a very long time. There are two main acceleration techniques: importance sampling and splitting on which we work. A combination with the faster randomized quasi-Monte Carlo methods is also a challenge we address in the joint team.

Associated team “OCERC” (Optimization of the energy consumption in wireless sensor networks)

Participants : Raouf Boutaba (Waterloo, responsible for Canada), Nizar Bouabdallah (responsible for France), Fatma Bouabdallah-Othman, Adlen Ksentini, Mario Rivero, Bruno Sericola.

OCERC is an associated team between DIONYSOS team from INRIA and the team of Professor Boutaba of the University of Waterloo. OCERC stands for “Optimization of the energy consumption in wireless sensor networks”. The collaboration aims at proposing new solutions to reduce the energy consumption in wireless sensor networks.

ECOS project “Mesh wireless networks and P2P multimedia applications: tools for guaranteeing Quality of Experience”

Participants : Adlen Ksentini, Gerardo Rubino.

This is a 3-year project (2009 – 2011) between France and Uruguay. The Uruguayan partner is the Engineering School of the University of the Republic, at Montevideo. The project concerns the study of tools allowing to reach good levels in the Quality of Experience in P2P networks for multimedia purposes, when the transport infrastructure is a mesh wireless network. The French coordinator of the project is G. Rubino.

STIC AmSud project “Performance evaluation and design of optical and wireless networks”

Participants : Nizar Bouabdallah, Gerardo Rubino.

This is a 2-year project (2009–2010) between Chile, France and Uruguay. The goal is the development of models and model analysis tools for the study of performance aspects in networks, mainly for optical and for wireless structures. The partners are: U. Técnica “Federico Santa María” and U. Adolfo Ibañez in Chile, U. de la República en Uruguay, U. Joseph Fourier, U. de Pau et des Pays de l'Adour and INRIA in France. The global coordinator of the project is G. Rubino (Dionysos, INRIA).
