iii ACKNOWLEDGEMENT It gives me a great pleasure to thank all those people who have helped me and contributed for the successful completion of this work. First of all, I would like to thank my advisor Dr. Ioan Raicu for giving me the opportunity to work under him on this project. The course I took under him triggered my passion in the field of distributed systems. His constant support and encouragement throughout my two years of graduate school has made my thesis possible. I also thank him for his patience, expertise and allowing me to work independently which eased me throughout my thesis. I would like to thank my parents Mr. Rajendran and Mrs. Sowdhamini Rajendran as well as my sister Mrs. Sheetal Balajee who have constantly supported me in boosting my morale. I dedicate this work to them. I would also to thank Dr. Lan and Dr. Sun for everything they taught me about Distributed Systems through their invaluable courses that broadened my knowledge. I want to thank Dr. Lan for being a member of the thesis examining committee.
