Abstract:

Future mobile broadband communication systems aim to provide a wide range of multimedia services (telephony, video conferencing, audio and video broadcasting, etc.) to a large number of users. In order to achieve a global coverage and reach remote users, satellite is foreseen to be a key component in the development of such networks. When compared to first-generation mobile satellite communication systems, these future satellite networks will need to provide significantly higher data rates whilst achieving very low bit error probability values. In order to keep the mobile user terminal as well

Abstract:

Live network multimedia applications (e.g., video conferencing, TV on demand) have been very popular in recent years and are expected to dominate Internet traffic in the near future. With multimedia and Internet-enabled devices being ubiquitous, mechanisms that ensure multimedia flows do not congest the Internet are crucial components of multimedia systems that are embraced rather than opposed by network service providers. The emergence of browser-based multimedia conferencing applications using the WebRTC protocol, an open source project aiming at Real-Time Communication (RTC) with Web, and w

Abstract:

The aim of this research is to enhance the quality of service in video applications when they are operating over error prone environments. With high compression ratio and low complexity block transform video coders, such as ITU-T H.263 standard algorithm for very low bit rate video coding, compressed video streams can be used for multimedia services. However, when transmitting compressed video streams over channels with degraded conditions, several problems arise and undermine the video decoder from correctly reconstructing the video signal.

Abstract:

The Internet Protocol Multimedia Subsystem (IMS) is a component of the 3G mobile network that has been specified by standards development organisations such as the 3GPP (3rd Generation Partnership Project) and ETSI (European Telecommunication Standards Institute). IMS seeks to guarantee that the telecommunication network of the future provides subscribers with seamless access to services across disparate networks. In order to achieve this, it defines a service architecture that hosts application servers that provide subscribers with value added services. Typically, an application server bundle

Abstract:

Multimedia communications over packet networks, and in particular the voice over IP (VoIP) application, have become an integral part of society. However, the unreliable and heterogeneous nature of packet networks has led to a best-effort delivery of services. Delay, limitation of bandwidth, and packet-loss rate all affect the quality of service (QoS). In this thesis, we address two important network impairments in the design of robust multimedia communication systems: packet delay-variation and packet-loss. Paper A considers the mitigation of the effect of packet delay-variation for audio comm

Abstract:

This work is motivated by the current trends in future broadband communication networks. On the one hand, the latest developments and experimentation with the Asynchronous Transfer mode (ATM) technology shows that that ATM is going to be the future transport mechanism in many private and public networks. This is driven by the need to efficiently support a large population of widebandlbroadband users with different data traffic characteristics and certain Quality of Service (QoS) guarantees. On the other hand, the interest in satellites and their role in the future broadband multimedia communic

Abstract:

Wireless communication is a rapidly growing field with many of its aspects undergoing constant enhancement. The use of cross-layer design (CLD) in current technologies has improved system performance in terms of Quality-of-Services (QoS) guarantees. While multimedia transmission is difficult to achieve, CLD is capable of incorporating techniques to achieve multimedia transmission without high complexity. Many systems have incorporated some form of adaptive transmission when using a cross-layer design approach. Various challenges must be overcome when transmitting multimedia traffic; the main c

Quality-of-service (QoS) guarantees have become critically important for the transmission of real-time multimedia traffic in next generation mobile wireless networks. The aim of this dissertation is to investigate the cross-layer design for support of delay bound QoS guarantees over fading channels. Providing diverse QoS guarantees presents a challenge due to the time-varying fading nature of wireless channels. Existing physical layer modelling is inadequate in supporting real time QoS metrics such as delay, hence adaptive techniques need to be extended to the upper-protocol layers. The first

However, there is no guarantee that packets sent via User Datagram Protocol will be received in their entirety. This is due to the absence of any packet error recovery mechanism in User Datagram Protocol. The purpose of this dissertation is therefore to investigate a
