MAESTRO members are currently involved in the
- Inria-Nokia Bell Labs (aka Inria-Alcatel-Lucent Bell Labs) joint laboratory: the joint laboratory consisted of three ADRs (Research Actions) in its first phase (2008–2012) and consists of six ADRs in its second phase (started October 2012). MAESTRO members participated in 3 ADRs.
- Inria-Alstom joint laboratory: the joint laboratory consists of four projects. MAESTRO members participated in project P11.
They also frequently collaborate with Orange Labs through CRE grants (CRE stands for “Contrat de Recherche Externalisée”).

- Nokia Bell Labs ADR “Network Science” (June 2013 – August 2016)
This ADR is coordinated by Philippe Jacquet. “Network Science” aims at understanding the structural properties and the dynamics of various kind of large scale, possibly dynamic, networks in telecommunication (e.g., the Internet, the web graph, peer-to-peer networks), social science (e.g., community of interest, advertisement, recommendation systems), bibliometrics (e.g., citations, co-authors), biology (e.g., spread of an epidemic, protein-protein interactions), and physics. The complex networks encountered in these areas share common properties such as power law degree distribution, small average distances, community structure, etc. Many general questions/applications (e.g., community detection, epidemic spreading, search, anomaly detection) are common in various disciplines and are being analyzed in this ADR “Network Science”. In particular, in the framework of this ADR we are interested in efficient network sampling and models of influence/information propagation over the complex networks.
- Nokia Bell Labs ADR “Self-Organized Networks in Wireless” (July 2008 – June 2016)
The topic of this ADR, coordinated by Bruno Gaujal for Inria and Laurent Roullet for Nokia, is user mobility. Many key features in mobile access networks rely on user velocity information in order to reinforce the perception of performance stability during mobility. Based on the analytical framework elaborated during the first phase that show the need for an efficient method of user speed estimation, a main objective of the research activity, strongly supported by the wireless eNB team (System Engineering and Modem), was to devise a procedure for user speed estimation or classification. M. Haddad and E. Altman have proposed three technical solutions to the LTE Mobility State Estimation problem. In particular, – Four patents have been submitted and filed (one in 2012, two in 2013, and one in 2014); – A white paper written by the joint team (INRIA/Bell-Labs and Wireless SE) summarizing the theoretical baseline of the methods, their performances, as well as the implementation issues, is documented.
- Alstom Project P11 “Data Communication Network Performance” (December 2013 – May 2016)
The objective of this study is to build a simulation platform and develop an evaluation methodology for predicting Quality of Service and availability of the various applications supported by the data communication system of train networks.
- Orange Labs CRE “Multi-Objective Optimization for LTE-Advanced Networks” (December 2012 – November 2015)
The objective of this Cifre thesis, allocated to A. Tall, was threefold: (1) to develop solutions based on stochastic approximations and optimal control for the optimization and setting of LTE-Advanced Networks; (2) to develop queuing models to capture the dynamics of the traffic and the physical layer mechanisms (e.g. relay, MIMO, scheduling); and (3) to apply the developed methods to engineering problems such the interference management, load balancing, optimization of coverage and capacity, and mobility management.
- Teletel/ESA Project (Sept. 2013 – April 2014)
This contract with the European Space Operations Centre, Darmstadt (Germany) had as partners MAESTRO, Thales-Alenia Space (France) and Teletel S.A. (Greece). Its objective was the application of a BitTorrent-like data distribution model to mission operations.
- Alcatel-Lucent Bell Labs ADR “Semantic Networking” (January 2008 – April 2013)
This ADR, coordinated by Isabelle Guerin Lassous (Inria project-team Reso) for Inria and Ludovic Noirie for Altcatel-Lucent, addressedt he new paradigm of “semantic networking” for the networks of the future brings together “flow-based networking”, “traffic-awareness” and “self-management” concepts to get “plug-and-play” networks. The natural traffic granularity is the flow. One task of MAESTRO was to elaborate on active queue management schemes that improve the fairness among flows. Another task concerned graph-based semi-supervised learning methods.
- Orange Labs CRE “Content-Centric Networking” (October 2010 – December 2012)
The objective of this grant (CRE) was to develop mathematical models for the analysis of Content-Centric Networks (CCN). This research focused on routing and caching policies. P. Nain was responsible for Inria. This work was done in collaboration with Inria team Planete, now Diana.
- Orange Labs CRE “Self Optimization in Networks” (October 2009 – September 2012)
This grant (CRE) from Orange Labs was related to a Cifre thesis allocated to R. Combes, whose advisors were E. Altman, S. Sorin (UPMC) and Z. Altman (Orange Labs).
- Orange Labs CRE “QoS and Quality of Experience” (2010-2011)
The objective of this grant (CRE) was to study the performance and to optimize protocols related to new applications over the Internet such as YouTube.
Older projects:
