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
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.

Satellite Data Communications for Remote Sensing and Broadband Connectivity. The remote, distributed location of many of Australia's primary industries preclude the use of consumer-oriented terrestrial wireless broadband services. In many instances, satellite communications provides the only feasible means of connectivity for telemetry, supervisory control and data acquisition, tracking and fleet management.

The remote, distributed location of many of Australia's primary industries preclude the use of consumer-oriented terrestrial wireless broadband services. In many instances, satellite communications provides the only feasible means of connectivity for telemetry, supervisory control and data acquisition, tracking and fleet management. Meteorology, remote sensing, irrigation, mining, oil and gas exploration, and fisheries are just a few examples of high-value applications of particular significance to Australia. This project will develop bandwidth efficient satellite communications technologies that greatly reduce cost and pave the way toward new market opportunities for broadband access and telemetry applications.

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.
