Habilitation à diriger des recherches (French qualification for conducting Phd theses)
This document is written as support to my French ”Habilitation `a diriger des recherches” (HDR) degree. Unlike a Ph.D. thesis, a HR thesis does not aim at providing a detailed description of a particular research problematic, but rather describes the various facets of responsibilities that I experienced as researcher and assistant professor since I obtained my Ph.D. My post-doctoral career started at Eurecom in January 2004, after having completed my Ph.D. entitled “Architecture and protocols for supporting routing and quality of service for mobile ad hoc networks” at ´ Ecole Polytechnique F´ed´erale de Lausanne EPFL, Switzerland in September 2003. After the postdoc, I joined the founding team of a startup company in Sophia-Antipolis,
France, working towards a range of intelligent wireless backhaul routing products for private and public networks. Four years later, I deliberately chose to join Eurecom as an assistant professor because of the experimental platform OpenAirInterface, which allowed me to work on practical aspects of wireless access network. This means working on aspects that are sometimes overlooked or not found interesting or even old fashioned by other researchers, or collecting and analyzing data from experiments to prove a concept or a point. Working with this platform is a unique experience, since one has to deal with many practical problems that sometimes lead to very interesting research avenues. Furthermore the platform is ideal for teaching, giving students hands-on experience and showing them the problems of real implementations. This document is composed of two parts. The first part describes the highlights of my research work I have been conducting after my Ph.D. The bulk of the text is based on existing and ongoing publications, but I have also added many new results, an introductory chapter summarizing all the works and putting them in context to each other, a chapter on the critical issues in cloud radio access network, and a conclusion chapter elaborating on my research methodology and giving directions for future work. The second part contains an extended CV, which includes teaching and supervising activities, project management and acquisition, as well as a selected list of my post-Ph.D. publications.
