My current research activities focus on telecomunication networks simulation and in particular on component based modeling techniques. In this scope I used to be involved and still participate to the following projects:

Funded Projects

The INFRA-SONGS ANR Project (2012–2015)

The SONGS Project is a follow-up to the USS-SIMGRID ANR Project (see also here). The goal of the SONGS project is to extend the applicability of the SimGrid simulation framework from Grids and Peer-to-Peer systems to Clouds and High Performance Computation systems. Each type of large-scale computing system will be addressed through a set of use cases and lead by researchers recognized as experts in this area. Any sound study of such systems through simulations relies on the following pillars of simulation methodology: Efficient simulation kernel; Sound and validated models; Simulation analysis tools; Campaign simulation management.

The EA DISSIMINET (Associated Team) (2011–2013)

Since January 2011, the MASCOTTE project-team is an associate team with ARS Laboratory at Carleton University, Ottawa, ON (Canada). This Franco-Canadian team will advance research on the definition of new algorithms and techniques for component-based simulation using a web-services based approach. On one hand, the use of web-services is expected to solve the critical issues that pave the way toward the simulation of systems of unprecedented complexity, especially (but not exclusively) in the studies involving large networks such as Peer-to-peer networks. Web-Service oriented approaches have numerous advantages, such as allowing the reuse of existing simulators, allowing non-computer experts to merge their respective knowledge, or seamless integration of complementary services (eg. on-line storage and repositories, weather forecast, traffic, etc.). One important expected outcome of this approach is to significantly the simulation methodology in network studies, especially by enforcing the seamless reproducibility and traceability of simulation results. On the other hand, a net-centric approach of simulation based on web-services comes at the cost of added complexity and incurs new practices, both at the technical and methodological levels. The results of this common research will be integrated into both teams’ discrete-event distributed simulators: the CD++ simulator at Carleton University and the simulation middle-ware developed in the MASCOTTE EPI, called OSA, whose developments are supported by an INRIA ADT (Development Action) named OSA starting in December 2011.

The OSA project (Supported by INRIA since 2005, currently by an ADT funding, 2011-2012)

OSA stands for Open Simulation Architecture. This is a development project for a new discrete event simulation platform. The original elements of this new platform are:

  1. the integration in the same tool of a large number of the Modeling & Simuilation concerns (modeling, developments, instrumenting, …)
  2. the extensive of Component-Based Sofware Engineering (CBSE) techniques, and more particularly the Fractal component model (for example, in order to ease the reuse and replacement of parts of the platform AND models —cf this paper — )
  3. the use of Aspect Oriented Programming (AOP) techniques in order to separate concerns
  4. an open (Open Source) and modular architecture, easy to use (automatic dependencies management based on a Maven repository), inspired AND based on Eclipse
  5. a collaborative development model (forge, wiki …)

OSA v0.6 is available on the INRIA forge with a demo of Peer-to-peer storage simulation.

1 Software Engineer position available to work on this project starting Sept 2010 (1 yr, renewable). Details about how to apply soon published here.
