Epigraph நாளள எ்ு் ந் ளையி் இ்ளல நா் யாு் தேவ் ளை ப ா்ளைைதள! எ்றா் ூட த ாராு ந் ா எ்ளற்ு் தோ்ைாு உ்ளைைதள ! Special Mention Ibrahim Houmed, R&D Program Manager, Orange Labs Yvon Gourhant, R&D Program Manager, Orange Labs Marion Duprez, R&D Program Manager, Orange Labs …for trusting me; for giving me the opportunity to do what ) like the most to do; for giving me a career break-through. To You, I owe all the success of my career! Acknowledgements Life is too short to acknowledge all those creative, beautiful and unpretentious minds, who make our journey worthwhile. Here, I get an opportunity to offer my gratitude to all those personalities, who really made a personal difference to me with their presence. Just saying 'thank-you' is far too little; I can't imagine my accomplishments without their support. To begin with, foremost, the first person to be acknowledged naturally is my advisor, Dr. Yvon Gourhant, who always maintained a rather pleasant ambiance with me and greatly inspired me to produce excellent research results by getting the best out of me. I will never forget my first interaction with him in the fall of 2010 when as an aspiring young doctoral candidate who had just arrived at Orange Labs, Lannion, I walked into his office and solicited him to describe to me some of the research he was involved with. I had never heard much of the technical details of ǲmobile backhaulǳ until that moment of my life and, truth be told, I did not understand much of what he explained that evening of what seemed to me – at that time – a very obscure field of telecommunications. There were memorable moments like this one that made the everyday life of a student pursuing Doctor of Philosophy, a rather amazing experience. To him, I owe all the knowledge that I have gained during the course of this research. Walking on my way back home after this meeting, the words of the great artist Pablo Picasso kept ringing in my head: ǲI am always doing that I cannot do, in order that I may learn how to do itǳ. I decided to embrace this philosophy and began my research hoping that this was the best way for me to gain the most knowledge; that turned out to be – in retrospect –a very wise choice. After three exciting years, having analyzed millions of experimental data points, having run thousands of simulations, having derived countless equations, and having learned much more than that I could have ever hoped for (all of these happened between 10pm and 4 am every night), I ultimately experienced a personal adventure of the greatest magnitude. During this unique process, my understanding on the mobile backhaul and for the field of telecommunications in general has grown exponentially, the collaboration with other researchers allowed me to produce some very interesting scientific results (15 international publications), and Yvon turned out to be a great advisor and one of the few people on the planet that no person could ever possibly dislike. He has been very pleasant to work with, in experiment upon experiment, always having time to listen and investigate any research issue I might have been struggling with. In short- I wrote, he improved! So, thank you Yvon, thank you for believing all the way and for carrying me to every hill and every valley. You lifted me up the whole way and I will always be grateful for everything you have done and for the all the credible works that have been done. While Yvon monitored my progress at close proximity, I must not forget to thank my professor, Prof. Djamal Zeghlache, who served as a distant supervisor. I would like to first thank him for accepting to be my academic supervisor despite his busy schedules. I would also like to thank him for supporting me at all the technical obstacles during my research and thank him the most for placing his un-ending support and confidence in me and for his views and appreciations for my research ideas. His support by providing valuable advice and start up ideas from his vast experience was an aiding factor in advancing this thesis with a much faster pace. Sincere thanks to Prof. Kaldoun Al Agha, Rapporteur, Université Paris-Sud, France, Prof. Raouf Boutaba, Rapporteur, University of Waterloo, Canada, for having to spend one of the most invaluable resources, ǮTimeǯ, for reviewing this dissertation thesis and offering valuable comments. I also wish to thank the professors and the members of my qualifying oral exam and defense committees, Prof. Dias De Amorim Marcelo, Président, Université Pierre et Marie Curie, France, Prof. Philippe Godlewski, Telecom ParisTech, France, Dr. Laurent Ciavaglia, Examinateur, Alcatel-Lucent Bell Labs, France, Dr. Olivier Festor, Examinateur, INRIA Nancy— Grand Est, France and all the anonymous reviewers of the international conferences I submitted and published my articles. They all transferred some part of their wisdom to me one way or another through suggestions, questions that intrigued as well as through constructive criticism. Aside from those people who were directly related to my research, a number of other people influenced my life directly, leading to obtain my Ph.D. Sometimes I'm lost at what my purpose is and am left wondering, why any of this matters. It is on those occasions, family comes - those who loved and cared for me the most, unconditionally. It's the starting boom of a chain reaction. My father, a retired mathematics professor today, who had spent several hours every evening with me personally, during the early years of my life, to teach me Probability, Statistics, Algebra. My brothers - the reason why I am doing this, those who kept insisting me that when I put work in and get things done, it doesn't go unnoticed; it could contribute to my best ever success and that I keep believing in all these years of sacrifices; not to forget to mention my last brother who passed away during the course of my doctoral research, who bought me my first laptop computer with his very own yearly savings. My two most lovely sister-in-laws, my niece- the little princess of our family, my nephews and last but not the least, my dearest friends from India, who replaced my physical presence in my home, for all their affection and constant support, and most of all, patience and understanding towards me, for tolerating my impossibilities. Orange Labs, my employer, for sponsoring all my professional trips, thus gave me the opportunity to attend some of the best conferences in the uploads/Litterature/ venmani-danielphilip.pdf
