Thinh P.Q. Nguyen Doctor of Philosophy in Engineering-Electrical Engineering and Computer Sciences University of California at Berkeley Professor Avideh Zakhor, Chair Recent years has witnessed phenomenal growth of the Internet. According to Internet Software Consortium, number of hosts has reached 171 millions in January 2003 versus 71 millions in January 2000 and 5.8 millions in January 1995. Part of this explosive expansion is the proliferation of multimedia data such as image, audio, and video on the Internet. The current "best-e#ort" Internet, however, does not guarantee Quality of Service (QoS) such as minimum bandwidth, packet loss rate, and delay which are critical to many multimedia applications. As such, many significant challenges remain to design and deploy delay sensitive multimedia applications over the Internet e#ectively. In this dissertation, we develop a path diversity framework for concurrent media streaming to a receiver using multiple routes. Without requiring QoS, our framework improves the quality of the streamed media via multiple routes created using either multiple senders or relay nodes, in order to increase available many approaches from the network architecture and protocols, to source and channel coding to in order to improve the overall quality of the streamed media.
