New high-performance iterative error correction codes. This project develops new error correction codes to underpin the success of next-generation communications technologies. The nature of the project presents significant potential for project outcomes to be beneficial to the Australian telecommunications industry in a wide range of application areas from optical communication to digital broadcasting.
Easing the Squeeze: Dynamic and Distributed Resource Allocation with Cognitive Radio. The radio spectrum is a scarce and valuable natural resource which is being squeezed by the rapid growth in wireless communications. Cognitive radios make efficient use of radio spectrum by dynamically reusing frequencies. This requires cognitive radios to sense the local environment and to control the interference caused to existing users of the spectrum. This project will design novel dynamic and distributed ....Easing the Squeeze: Dynamic and Distributed Resource Allocation with Cognitive Radio. The radio spectrum is a scarce and valuable natural resource which is being squeezed by the rapid growth in wireless communications. Cognitive radios make efficient use of radio spectrum by dynamically reusing frequencies. This requires cognitive radios to sense the local environment and to control the interference caused to existing users of the spectrum. This project will design novel dynamic and distributed resource allocation algorithms for cognitive radios in order to significantly improve their performance using techniques from extreme value theory, game theory and mechanism design and large random matrix theory.

Software Defined Networking: Transforming Emergency Operations. The project aims to improve the effectiveness and efficiency of Australia's emergency operations, for example, bushfire and rescue missions, by providing robust and integrated communications systems for police and the emergency services. Emergency communications systems are currently fragmented by the different technologies, creating disconnected islands of information. The project aims to provide techniques that allow multiple wire ....Software Defined Networking: Transforming Emergency Operations.

Emergency communications systems are currently fragmented by the different technologies, creating disconnected islands of information. The project aims to provide techniques that allow multiple wireless technologies to communicate seamlessly using modern software-defined networking solutions.Read moreRead less
Autoconfiguration of critical network infrastructure. In 2000, Vitek Boden hacked into Maroochy Shire's sewerage system, causing hundreds of kilolitres of raw sewage to flow into a public area, causing financial and environmental damage, and the potential for the spread of life-threatening disease. The goal of this project is to improve the security of Australia's critical infrastructure, for instance, electricity and water supply. The project’s approach is to simplify the critical bottlenecks i ....Autoconfiguration of critical network infrastructure. In 2000, Vitek Boden hacked into Maroochy Shire's sewerage system, causing hundreds of kilolitres of raw sewage to flow into a public area, causing financial and environmental damage, and the potential for the spread of life-threatening disease. The goal of this project is to improve the security of Australia's critical infrastructure, for instance, electricity and water supply. The project’s approach is to simplify the critical bottlenecks in communication between plant equipment and company management, namely, the firewall that protects the critical plant equipment from viruses and hackers. Simplification will improve transparency and hence reduce the possibility that security holes allow an incident similar to that of this incident, or worse.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
Network Management in a World of Secrets. The aim of this proposal is to provide world leading measurement and management techniques for the Internet and other telecommunications networks. In particular, the methods will improve privacy of network participants (customers and providers) while simultaneously improving network performance. Additionally, the project will create expertise in an area of great future interest -- privacy preserving computation -- expertise that can be transferred to stu ....Network Management in a World of Secrets. The aim of this proposal is to provide world leading measurement and management techniques for the Internet and other telecommunications networks. In particular, the methods will improve privacy of network participants (customers and providers) while simultaneously improving network performance. Additionally, the project will create expertise in an area of great future interest -- privacy preserving computation -- expertise that can be transferred to students and the next generation of innovators.
Apart from these benefits, the research will provide exposure of Australian research strength in an area of world-wide public interest. Results concerning Internet reliability are of particularly high impact. 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.
Adaptive Modulation For OFDM Signals. The sub band Signal To Noise Ratio in an OFDM communications channel varies by as much as 30 dB. In order to optimise the bandwidth efficiency of OFDM signalling it is desirable to adapt the chosen modulation technique such as M-ary QAM to the SNR available in sub bands. In this way high quality channels transmit the highest bit rates, whilst low quality channels accommodate the lowest bit rates. The net result is that the capacity of the communications link ....Adaptive Modulation For OFDM Signals.
