Recent advances in network bandwidth and processing power have led to the emergence of real time multimedia streaming applications and it is expected that such applications will become an even more dominant source of traffic in future computer networks. Quality of service studies for real-time applications in high-speed networks, point to the importance of the transport layer functionality in admission control, monitoring end-to-end delays, and network bandwidth adaptability. The project will study, design, develop and analyse a comprehensive model for the virtual transport layer to satisfy the necessary quality of service requirements for the next generation of multimedia-based applications.Read moreRead less

Current Internet only supports limited quality of service (QoS) within isolated domains. This project allows critical applications to be deployed over the global Internet. The project employs a programmable architecture for composing services and intelligent software elements for negotiating acceptable QoS responses for individual application flows over multiple administrative domains. The architecture employs DiffServ's aggregation property to make it scalable for the Internet core. Successful outcomes would open the floodgates, allowing the development and deployment of applications such as high quality videoconferences, live sport broadcasts, remote medical services, network games, real-time on-line educations, and multimedia distributions.

Fair Intelligent Quality of Service Control and Path Discovery Mechanisms for Internet Scalable Architectures. Until now the Internet only provides best effort service without guaranteeing the timeliness or actual delivery of data. Quality of Service (QoS) architectures have been proposed but not deployed due to a fundamental problem: either the architecture is not scalable or it does not guarantee end-to-end QoS. The project tackles the problem by introducing mechanisms for network path discove ....Fair Intelligent Quality of Service Control and Path Discovery Mechanisms for Internet Scalable Architectures. Until now the Internet only provides best effort service without guaranteeing the timeliness or actual delivery of data. Quality of Service (QoS) architectures have been proposed but not deployed due to a fundamental problem: either the architecture is not scalable or it does not guarantee end-to-end QoS. The project tackles the problem by introducing mechanisms for network path discovery in the network core. The solution allows an integration of both scalability and end-to-end QoS architectures. The outcomes allow network providers to provision network resources efficiently, to develop competitive Internet-based products; and the service providers to develop quality services such as high quality IP phone, multimedia distributions.

PROVISION OF ARBITARY COMPLEX SERVICES ON THE MOBILE INTERNET. Within the next few years, mobile and wireless access to the Internet will very likely become the norm. These networks will use widely different networking technologies. Moreover, the services provided, will be accessed by the users using a wide variety of devices, with significantly different capabilities. Thus to provide seamless access, the system must adapt it self to the operating environment. These adaptations need to occur at ....PROVISION OF ARBITARY COMPLEX SERVICES ON THE MOBILE INTERNET. Within the next few years, mobile and wireless access to the Internet will very likely become the norm. These networks will use widely different networking technologies. Moreover, the services provided, will be accessed by the users using a wide variety of devices, with significantly different capabilities. Thus to provide seamless access, the system must adapt it self to the operating environment. These adaptations need to occur at different levels of the system, in isolation. This project is aimed at investigating the implications of adaptation decisions being taken in isolation at different levels on the system stability and performance.Read moreRead less

This project aims to design and implement a lightweight security framework for Low Power Wide Area Networks (LPWAN). Smart cities are estimated to have a worldwide market value of US$1.5 trillion by 2020, and LPWAN will provide connectivity to 90% of low bandwidth, smart city applications such as smart metres and smart buildings. Many of these applications are deployed in mission-critical infrastructure such as airport, train station, hospital and government campuses, which have strong security requirements. Before the ubiquitous deployment of such new technology, a strong security framework needs to be developed and implemented to minimise enormous economic and social consequences of future malicious attacks to LPWAN.Read moreRead less

The revenue generated from traditional telecommunication services is continuing to drop. New value-added services such as multimedia services become the fastest growing revenue-generating sector in Australia's telecommunications industry. The ubiquitous presence of scaling behaviour in network traffic presents a big challenge for delivering better Quality-of-Service (QoS) which is demanded by the new services. A complete understanding of the scaling behaviour and its impact is very important. This research addresses a key problem of defining the timescale range of interest for the scaling behaviour. The research outcome benefits a number of areas, which are all critical for developing enhanced QoS support and better network management.Read moreRead less
