MOCQUASIN

• Title: Monte Carlo and Quasi-Monte Carlo for rare event simulation

• INRIA principal investigator: Bruno Tuffin

• International Partner:

  • Institution: Université de Montréal (Canada)

  • Laboratory: Département d'informatique et recherche opérationnelle

  • Researcher: Pierre L'Ecuyer

• Duration: 2008 - 2013

• See also: http://www.irisa.fr/dionysos/pages_perso/tuffin/MOCQUASIN/

• Abstract: The goal of MOCQUASIN is to design efficient Monte Carlo and quasi-Monte Carlo simulation methods and to apply them to models in telecommunications. Simulation is indeed often the only method to analyze complex and/or large systems, but also suffers from inefficiency. Two specific situations on which we will focus are rare events, and revenue management. In the two cases, we want to deal with dependent individual events or decisions, a realistic situation requiring adapted solution techniques. The inefficiency of the standard simulation is a known issue to compute the probability of rare event since getting it only once requires in average a long simulation time, but most of the literature has up to now assumed independence in the models. The other framework, revenue management in telecommunications, is the situation of providers trying to define valid offers and capacity investments in front of complex demand models. Here too, a change in the decision of an actor has an impact on the others that has to be taken into account.

ECOS project with Uruguay

• Title: Mesh wireless networks and P2P multimedia applications: tools for guaranteeing Quality of Experience

• INRIA principal investigator: Gerardo Rubino

• Duration: 1 2009 - 12 2011

• International Partner:

  • Institution: University of the Republic, Montevideo, Uruguay

  • Laboratory: Institute of Computer Science (InCo)

  • Researcher: Héctor Cancela (Dean of the Faculty of Engineering, Uruguayan Responsible of the project)

• Abstract: The project consists in developing tools for QoS and QoE analysis of communication networks. We produce techniques for analyzing these structures using Monte Carlo procedures. We also develop tools allowing to reach specific levels in the Quality of Experience of transport sructures for multimedia purposes, in particular when the underlying network is a mesh wireless system.

STIC Algérie

• Title: Utilisation de la plate-forme de test Senslab pour le projet irrigsense

• Principal investigator: Adlen Ksentini

• International Partner:

  • Institution: Centre de Recherche sur l'information Scientifique et Technique (CERIST)

  • INRIA: three teams involved: Dionysos, ASAP and Cider

  • Laboratory: Department of Theories and Computer engineering

  • Researcher: Abdelouahid Derhab

• Duration: 2011 - 2013

• Abstract: This collaboration aims at defining new protocols for data collecting in Wireless Sensor Networks, and evaluate them with the senslab platform. After validating the proposed protocols, CERIST intends to deploy them in the context of the project (Algerian) "Sensirrig", which aims at using sensors for agricultural irrigation.
