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 project aims to improve the accuracy of automatic location identification of GPS enabled handsets in third-generation cellular networks via a modified Differential GPS method. The proposed sub-metre location ability will be a value-added service of the network providers and will appeal to a wide sector of users. The challenge is to develop a cost effective solution by utilising existing network infrastructure. We propose to use the GPS timing units in 3G networks for deriving local GPS position corrections; and to transfer these corrections to the users via the 3G data bursts of the beacons or other user data broadcasts.Read moreRead less

Eco-NextNet: An Ecologically-Inspired Adaptive Network Resource Management Framework for a Sustainable Next Generation Mobile Network for Ubiquitous Services. Ubiquitous communications service is the most important element of today's societies. In urban and rural areas of the country as well as at the time of natural disasters such as bushfires, floods, cyclones, it is vital to devise alternative schemes to create and sustain on-demand telecommunications services.

Ubiquitous communications service is the most important element of today's societies. In urban and rural areas of the country as well as at the time of natural disasters such as bushfires, floods, cyclones, it is vital to devise alternative schemes to create and sustain on-demand telecommunications services. In most cases it is not the lack of technology that hinders the implementation of a reliable communications service, but it is the resource allocation. In this project we propose a novel sustainable resource management framework inspired by natural ecological systems to solve the above problem. Upon completion, Australia will be in forefront of technologies related to the management of complex networks.Read moreRead less

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
Development of a new transport layer protocol to provide secure broadband internet connections via satellite to rural and remote areas. Satellite links form an essential part of broadband connectivity to rural and remote areas. Effective use of the internet over satellite links is therefore essential if B2B (Business-to-Business) and B2C (Business-to-Consumer) E-commerce is to develop in these areas. In many application networks, particularly virtual private networks (VPN), secure transmission ....Development of a new transport layer protocol to provide secure broadband internet connections via satellite to rural and remote areas. Satellite links form an essential part of broadband connectivity to rural and remote areas. Effective use of the internet over satellite links is therefore essential if B2B (Business-to-Business) and B2C (Business-to-Consumer) E-commerce is to develop in these areas. In many application networks, particularly virtual private networks (VPN), secure transmission is important to avoid fraud and maintain privacy.
Satellite links introduce a long delay (latency) in the transmission path and existing secure internet protocols do not handle this well. This is because in many situations, it is a requirement that the secure connection be implemented not only independently of the
satellite service provider but also in a reliable and efficient way.
This project will develop new practical solutions so that secure and reliable end-to-end connections can be provided over the satellite links.
