This project aims to develop methods for improving the service quality of the internet by better management of congestion. Improved service quality will be evident to internet users in the form of reduced delay and data loss. The proposed research is significant because as well as improving service quality, it will facilitate delivery of internet services over poor quality communications infrastructure such as is present in many remote and regional areas of Australia. It also will result in more efficient utilisation of telecommunications infrastructure. The project will deliver implementations in the form of software which is easily installed in any computer.Read moreRead less
Incorporating network-level knowledge into Quality of Service control mechanisms for wireless LANs. Expansion of Wireless LANs as primary access technology for mobile computing devices has resulted in growing expectations of continuous area coverage and controlled Quality of Service. The work published to date defines QoS control mechanisms for a single WLAN cell, but fails to address challenges of multiple-cell networks. We aim at designing network-wide resource management mechanisms to dynamic ....Incorporating network-level knowledge into Quality of Service control mechanisms for wireless LANs. Expansion of Wireless LANs as primary access technology for mobile computing devices has resulted in growing expectations of continuous area coverage and controlled Quality of Service. The work published to date defines QoS control mechanisms for a single WLAN cell, but fails to address challenges of multiple-cell networks. We aim at designing network-wide resource management mechanisms to dynamically allocate resources to cells and users, taking into account user mobility and radio interference between multiple cells. Benefits from this research include competitive advantage to operators who will be able to differentiate service offerings and guarantee agreed QoS to their customers.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
Internet traffic-matrix synthesis. This project will enhance research and development in Internet engineering by providing basic inputs to test and validate new ideas. The result will be a more efficient, reliable, and robust Internet.
Multi-channel reconfigurable high dynamic range digital receivers. Wireless communication systems have important defence and commercial applications, most obviously in the form of the mobile telephone network. Future wireless systems will require much higher levels of performance, in the form of ability to receive and distinguish signals from multiple sources that are physically close together and transmit on similar frequencies.

Wireless communication systems have important defence and commercial applications, most obviously in the form of the mobile telephone network. Future wireless systems will require much higher levels of performance, in the form of ability to receive and distinguish signals from multiple sources that are physically close together and transmit on similar frequencies.
In this project we will develop a test system that will allow us to undertake research on new algorithms that will achieve these higher levels of performance. Our objective is to demonstrate dramatic improvements in the capabilities of receivers for future generation mobile phone and defence surveillance systems.

Advances in the Verification of Communication Protocols. Australia's economy is becoming increasingly dependent on many complex distributed systems. Some important examples are the Internet, electronic commerce, financial networks, transportation systems, health care networks, telecommunication networks, defence systems, intelligent manufacturing systems and organisational workflow management systems.

Australia's economy is becoming increasingly dependent on many complex distributed systems. Some important examples are the Internet, electronic commerce, financial networks, transportation systems, health care networks, telecommunication networks, defence systems, intelligent manufacturing systems and organisational workflow management systems. Failure in these systems can result in serious financial loss (in banking applications) and loss of life or serious accidents in safety critical areas (medical, transport and defence applications). It is thus of utmost importance that distributed systems are designed correctly. This project aims to advance the state of the art in verifying that distributed systems will work correctly.Read moreRead less

The Information and communications technology (ICT) industry has direct contribution to the economy as well as being an enabler across many areas of potential growth. This project aims at solving a key problem currently inhibiting an entire class of wireless ICT applications with strict quality-of-service requirements.
Another important impact is the bridging nature of the project, cutting across traditionally separated disciplines within telecommunications. The cross-layer design methodologies are the first steps towards interdisciplinary work, opening up new areas of research with high potential of innovation. Establishing an R&D niche of excellence will inspire more efforts into these areas, providing a knowledge base for Australia.Read moreRead less
