Audio, video, and still image data dominate our daily lives. Such information has commercial and strategic importance. It is invaluable in crime prevention: for example, video from security cameras. The protection of commercially valuable material against piracy and sensitive information against security breaches is vital to our economy and our safety. This project addresses these issues, by developing new, secure watermarks and fingerprints to protect digital information. Such watermarks can also protect radio communication channels, which is important due to the rising demand for wireless connectivity.Read moreRead less

Optical-OFDM provides Australia with an opportunity to develop a new, high-tech, easy-to-export technology with a very large market potential spanning three key communications markets: wireless personal-area networks, local-area networks and long-haul (80-4000 km) optical networks. It is based on innovative Australian technology generated from two research strengths: photonics and OFDM. OFDM is already the basis of most non-optical broadband systems, including digital broadcasting and ADSL. Patent applications have been filed. One application enables bandwidths to rural and remote communities to be quadrupled without laying new cables. By launching off this local market Australian industry can develop a world leading industry.Read moreRead less

This is in line with the Priority Goals set by the Minister for Education, Science and Training, as it will put Australia into the unique position in the information age.Read moreRead less
Dynamic Scheduling and Stochastic Control for Sensor Networks. Sensor networks are rapidly becoming important in applications from environmental monitoring, navigation to border surveillance. However, due to bandwidth constraints, even very simple networks have proven to be very complex to properly control. It is now necessary to efficiently allocate the 'limited available bandwidth' to sensors in order to share the most valuable data over the network. Therefore, this project proposes new techn ....Dynamic Scheduling and Stochastic Control for Sensor Networks. Sensor networks are rapidly becoming important in applications from environmental monitoring, navigation to border surveillance. However, due to bandwidth constraints, even very simple networks have proven to be very complex to properly control. It is now necessary to efficiently allocate the 'limited available bandwidth' to sensors in order to share the most valuable data over the network. Therefore, this project proposes new techniques using concepts of dynamic sensor scheduling and stochastic control to provide computationally feasible and near optimal solutions to the limited and varying bandwidth problem. This work will greatly enhance the operational performance of distributed sensor networks.Read moreRead less

Towards an Information Theory for Communication-Limited Control Systems. In a number of emerging applications in communications, manufacturing and defence, various dynamical systems are measured and controlled by transmitting feedback over digital communication channels.

In a number of emerging applications in communications, manufacturing and defence, various dynamical systems are measured and controlled by transmitting feedback over digital communication channels. In such situations, the often limited data rate available for transmissions can have a significant negative impact on the overall objectives. This proposal aims to develop techniques for analysing and designing such systems, and to delineate the fundamental limits to their performance. This has the potential to contribute to a greater understanding of the behaviour of many real systems which combine communications and control in feedback loops.Read moreRead less
