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
Adaptive Transmitters in Wireless Communication Networks. The mobile Internet requires at least an order of magnitude
lager data rate to be delivered to the mobile user rather
then from the mobile user. This high level of capacity asymmetry is a
challenge for current cellular mobile systems being designed for duplex telephony with equal capacity from
and to the mobile user. In this project an adaptive transmitter-receiver
algorithm is proposed. The algorithm will provide a significan ....Adaptive Transmitters in Wireless Communication Networks. The mobile Internet requires at least an order of magnitude

Tools and models for measuring and predicting growth in internet addressing and routing complexity. We analyse patterns in the allocation and actual use of Internet Protocol version 4 (IPv4) addresses to predict the technical and market pressures for deployment of IPv6. The utilisation models will help evaluate the potential for emerging markets in scarce IPv4 address prefixes to increase costs to the end-users of Australia's future national broadband network.

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

The telephone network is a critical platform for communication, used by all levels of society - government, the private sector and the general public. The shift to telephone services based on voice-over-IP technology holds the promise of significantly reducing costs for communication services. However, the Internet has long been plagued by a variety of network attacks. Reports of denial-of-service attacks, viruses and break-in attempts frequently appear in the world news. A major impediment to confidence in voice-over-IP services is the risk of attacks on its infrastructure, and the potential for using weaknesses in voice-over-IP infrastructure to launch attacks on the existing telephone network.Read moreRead less
