Addressing the Challenges for TCP over Multihop Wireless Networks

Von der Philosophisch-naturwissenschaftlichen Fakultät angenommen. Berne. I am really grateful to many people that directly or indirectly contributed to this work. I do apologize if I do not explicitly name all of them here, but I indeed thank everyone who helped. First I want to express my gratitude to my advisor, Prof. Dr. Torsten Braun. His trust in my work even when things seemed not to be on track was fundamental for my success. His clever advices always helped me to shape my research work toward something more meaningful. Professor Braun gave me the opportunity to work in the NCCR/MICS project in which I developed the concepts presented in this thesis. He always encouraged me to publish my research results in good conferences and so provided me great opportunities to meet other researchers from whom I got invaluable feedbacks. I also want to thank Prof. Dr. Christian Tschudin for having accepted to conduct the " koreferat " of this work, and Prof. Dr. Oscar Nierstrasz for having accepted to be the co-examinator of the thesis. My experience at the University of Berne was very positive. Even though the time was very short for me as a whole, I had some insightful discussions with most of my fellow PhD students. I want to thank the new PhD candidates for their kind assistance whenever I needed it. I thank Marc Danzeisen for the nice talks we had from which I learned a lot about telecommunications carriers. I thank Marc Heissenbüttel for the fruitful discussions we had in the scope of the NCCR/MICS project in which we both developed our thesis concepts. I thank Matthias Scheidegger for his insightful clues on subtle Unix/linux related issues. I want to thank Marc Alain Steinemann for the various social activities he organized very well. Special thanks go to Attila Weyland with whom I frequently discussed many general issues. I really appreciated his friendship in many instances. I also want to thank Dr. Florian Baumgartner, who has been working as a postdoc research assistant and lecturer at IAM. I really learned a lot from his work experience. iii during my first year of studies but continued at the university as a postdoc research assistant and lecturer. I really learned a lot from his work experience. I thank my former colleagues at the University of Berne. In particular, I thank Roland Balmer, Silvia Stattenberber, and Dr. Günther Stattenberger …
