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
Characterisation of Internet Traffic Matrices. The benefits to the community of characterisation of Internet traffic matrices arise because this information is used in the design of efficient and reliable networks. This is a genuine example of using the data we have more cleverly, rather than throwing money at a problem. Better information will result in the Internet becoming more efficient, and therefore cheaper, and at the same time more reliable.
Ensuring the Robustness of IP Routing. The Internet is by its nature international, and so any such effort to model and understand it must be somewhat international. However, Australia has longer network paths to the rest of the world and the routing protocols' operation depends on this latency. This emphasizes why Australia must participate in such research: to ensure that Australian issues are considered when Internet protocols are designed. This project will directly deliver a more robust Int ....Ensuring the Robustness of IP Routing. The Internet is by its nature international, and so any such effort to model and understand it must be somewhat international. However, Australia has longer network paths to the rest of the world and the routing protocols' operation depends on this latency. This emphasizes why Australia must participate in such research: to ensure that Australian issues are considered when Internet protocols are designed. This project will directly deliver a more robust Internet for Australia, international exposure in an area of general interest, the potential for patents, and the development of commercially valuable expertise and measurement infrastructure.Read moreRead less
Delivering guaranteed quality of service over IP networks. The next revolution in the Internet will be to offer end-to-end Quality of Service (QoS) guarantees, in the form of maximum delay, delay variation and probability of packet loss, or minimum throughput. There are no existing techniques capable of delivering end-to-end QoS guarantees. This project will develop credit-based controls, instead of the usual rate-based controls, that can deliver these required QoS guarantees. These QoS guarante ....Delivering guaranteed quality of service over IP networks. The next revolution in the Internet will be to offer end-to-end Quality of Service (QoS) guarantees, in the form of maximum delay, delay variation and probability of packet loss, or minimum throughput. There are no existing techniques capable of delivering end-to-end QoS guarantees. This project will develop credit-based controls, instead of the usual rate-based controls, that can deliver these required QoS guarantees. These QoS guarantees will enable the development and deployment of entirely new services on the Internet. This project will give Australian industry the opportunity to create the next generation Internet. Therefore this project represents a Frontier Technology.Read moreRead less
Modelling Human-Body Effects on Indoor Multiple-Input Multiple-Output Channels for Broadband Wireless Systems. Multiple-Input Multiple-Output (MIMO) technologies use a number of antennas to send multiple signals as a way to significantly increase the speed, range and reliability of a wireless network. The upcoming IEEE 802.11n standard, which includes MIMO in its specifications, will offer up to eight times the coverage and up to six times the speed of currently available IEEE 802.11 products.

Modelling, Measurement and Control of the Internet. The demands made of modern high-speed data networks, such as those that make up the Internet, are increasing rapidly in terms of both the quantity and quality of service required.
So that these demands can be satisfied, it is necessary that network operators, or even the network itself, take measurements and make control decisions.

So that these demands can be satisfied, it is necessary that network operators, or even the network itself, take measurements and make control decisions. Depending on the service, there is a need to do this over very short timescales (fractions of a second), or longer
timescales (minutes or even weeks).
By developing innovative mathematical models of network behaviour,
this project will deliver improved methods for measurement and
control of the Internet.Read moreRead less

The project proposes to create a novel technology to measure soil moisture. Accurate knowledge of soil moisture profiles at high resolution is important for sustainable land and water management including efficient irrigation scheduling and cropping practices. A passive multi-band soil moisture-measuring radiometer at L-, Ku- and Ka-bands is proposed. The radiometer comprises a three-band shared aperture antenna array, a receiving electronics, a digital controller and a data logger. The array antenna comprises dual polarised stacked patch elements. Beamforming networks form agile beams to scan the ground. Sensitive radiometer receivers apply brightness temperature downscaling for high resolution. The high-resolution passive radiometer would revolutionise airborne soil moisture monitoring by removing the mechanically steerable bulky and heavy scanheads.Read moreRead less

This project aims to design and develop low-cost reconfigurable end-user antennas that could be integrated with low-earth-orbit satellites so regional and remote Australians can access broadband. While broadband is taking its place alongside water and electricity as essential infrastructure, people in regional Australia lack genuine broadband services. These antennas are expected to give these communities reliable access to e-health services and distance education, and make their businesses more productive with access to new markets. The proposed antennas should also make broadband services available in the air, at sea, or on the move.Read moreRead less
