“…Much of work has been carried out to find efficient and robust packetisation algorithms. Most of them either modify the standard IP protocols or involve complex algorithms using feedback channels adding overheads to the video packets [3,4,5]. We propose a simple packetisation method from the header compression point of view.…”

“…Third-generation wireless systems, such as CDMA2000 and UMTS, use IP as the transport mechanism for packet switched based communication [4]. Much research has been conducted into modifications of IP and the underlying protocols, such as RTP/RTCP and UDP, for wireless applications [5][6][7][8]. Most of this research focuses on the reliable transmission of IP over error-prone wireless networks.…”

Following its success over wired networks, the deployment of the Internet Protocol (IP) over wireless networks is an increasingly popular topic. Protocol optimisations implemented at this level only consider the traditional Internet applications. Path maximum transfer unit (MTU) discovery algorithms are designed to avoid packet fragmentation along the transmission path and hence improve protocol efficiency. However, the design criteria do not take into account the potentially significant influences on the performance over the wireless links. A theoretical analysis is presented of the effect of MTU size upon the performance of wireless video. The theoretical calculation is based on a distortion model, which accurately estimates the video quality in terms of average frame peak signal-to-noise ratio (PSNR). The theoretical analysis are validated for MPEG-4 coded video transmission over a simulated UMTS network.

“…Similar guidelines can be found for MPEG-4 streams in [106] [107]. A study on optimal packetization for MPEG-4 video using RTP has been performed in [108], with the suggestion for an adaptive scheme that varied video packet size with partition size (namely header and motion data). This adaptive scheme analysis could be performed also on audio stream.…”

First and foremost, I would like to thank NTU School of Computer Engineering and ST Microelectronics Asia Pacific Pte. Ltd. for granting me the opportunity and scholarship to undertake the Ph.D. programme and providing me with a very conducive research environment at Parallel and Distributed Computing Center (PDCC) for my research activities. The road to this thesis has been long but rewarding. However, without the help of the following people, this work could never make its way to the current degree of recognition. I would like to express my deepest gratitude to my supervisor Dr. Lau Chiew Tong and my co-supervisor Dr. Benjamin Premkumar, from whom I have received an unconditional support during the course of this work. Their guidance and encouragement throughout difficult times are invaluable towards the completion of this research. My attachment at ST Microelectronics was a fruitful experience because I had the chance to seek feedback on how the industry would perceive my research. I have benefited from the interaction with people in this R&D center. My heartfelt thanks to my supervisor there Ms. Sapna George and Mr. Javed Absar, whose excellence and experience in signal processing field are truly inspiring. Next, I would like to thank the PDCC staff for their support, especially Irene Goh who is always there to solve our technical difficulties. A big thank you to those involved in the listening test, both from PDCC and ST Microelectronics. To my friends who never fail to console me in time of difficulties, I can never thank enough. Last but not least, I must really thank God and my parents for their love, care, and their undying confidence in me. To my beloved sister and brother, the guardian force of my life, I dedicate this work. iv
