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. 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 proposed project will provide a diverse range of benefits for the nation, by providing future solutions to address a number of key telecommunication networking requirements in Australia. One such area is the provision of broadband connectivity to rural and remote regions of Australia. It is well known, that wireless relay networks could potentially provide low-cost networking infrastructure for rural and remote communities. The solutions developed in this project will enable a wider deployment of such networks, as they would increase the capacity of these networks both in terms of bandwidth and their coverage. This is of major benefit to Australia, due to our large desert land-mass and sparsely populated remote and rural communities.Read moreRead less
VHF wireless technologies for last-mile Internet access in regional Australia. One of Australia's most vexing social issues is the provision of the last-mile Internet connection in regional Australia. The BushLAN team will solve this problem at minimal cost by developing a cellular wireless local area network operating on the TV band I channels (45-70 MHz). We will do this by developing a wireless modem whose design takes into account the properties of radio propagation in the Australian enviro ....VHF wireless technologies for last-mile Internet access in regional Australia.

Summary
Infrastructure for wireless Internet technology development for rural Australia. Three nodes of a low-power, very-high frequency digital wireless network will be installed at two locations in the Australian National University and one location at the University of Canberra. An additional node will then be located a further distance away (> 50 kms) in the ACT. This network will allow the development of novel technology for moderate speed (>100 kbps) non-line of sight wireless Internet access o ....Infrastructure for wireless Internet technology development for rural Australia. Three nodes of a low-power, very-high frequency digital wireless network will be installed at two locations in the Australian National University and one location at the University of Canberra. An additional node will then be located a further distance away (> 50 kms) in the ACT. This network will allow the development of novel technology for moderate speed (>100 kbps) non-line of sight wireless Internet access over ranges of 3-100 km for potential use by regional Australian Internet providers. The network will also catalyse research and training in wireless communication technology , digital signal processing, and computer networking.Read moreRead less

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
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.

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

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
