We propose that this communications technology can be used as a platform to develop a completely new family of sensors ideally suited to medical monitoring. Specifically, we will develop VCSEL based technology for measurement of heart activity and sensing of blood flow in skin and tissues. This will provide novel sensors for heart monitoring and imaging, and management of skin disorders (burns and cancer).Read moreRead less
Quality of Service in 3G Wireless Systems with Hybrid Networks. The increasing demand of providing Internet-based services over the mobile handsets has led to the transition from circuit-based 2G systems to packet-based network architectures in the emerging 3G systems. A major technical challenge for this paradigm shift is maintaining quality of services (QoS) for the existing data and voice and future Internet services such as streaming multimedia over such packet switching networks.

A major technical challenge for this paradigm shift is maintaining quality of services (QoS) for the existing data and voice and future Internet services such as streaming multimedia over such packet switching networks. This project aims to investigate end-to-end QoS solutions in the 3G systems. Australian mobile Internet and voice carriers will significantly benefit from this technology.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.

Imaging of properties of coherent elastic light scattering from turbid biological media. Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer t ....Imaging of properties of coherent elastic light scattering from turbid biological media. Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer tissue state and morphology indirectly based on phase delay, speckle, and angle-resolved scattering. We will break new ground in correlating the structure and function of in situ epithelial tissue and cells to light scattering enabling, e.g., the detection of mitosis and apoptosis in cells buried in thick, turbid media, and of cancers and precancers in vivo.Read moreRead less
Advances in optical coherence tomography. We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation. These advances are aimed at improving resolution to the 1-5 micron range, which should allow a breakthrough to sub-cellular in vivo imaging, making visible sample histology in situ, which is currentl ....Advances in optical coherence tomography. We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation. These advances are aimed at improving resolution to the 1-5 micron range, which should allow a breakthrough to sub-cellular in vivo imaging, making visible sample histology in situ, which is currently not possible. We also plan to make advances in the key area of scanning delay line technology by employing acousto-optics in OCT for the first time. Acousto-optics conveys advantages in no-moving-parts, scan-speed and accuracy.Read moreRead less

This project aims to propose novel privacy preserving schemes that can protect the privacy of individuals in the era of Internet of things and machine learning. In the recent years, most Australian organizations have been a target of privacy and cybersecurity attacks, affecting their data and network systems. The expected outcomes of this project are privacy preserving schemes that can prevent attackers from compromising the private information of individuals in IoT and machine learning services, and thus significantly improve the protection against cybersecurity attacks. Significant benefits in social wellbeing and security are expected for all industry, government, and service sectors that collect data about people.Read moreRead less

This project brings together an international, multi-disciplinary team to develop innovative, high-resolution techniques to identify diseased tissue. Success will result in a new medical imaging technique allowing clinicians to quantify the mechanical properties of tissue, effectively creating a high-resolution image of what the tissue 'feels' like. This may help them to more accurately identify cancerous tissue during surgery and reduce rates of recurrence. It could aid in tissue engineering and regeneration and will provide a new database of tissue mechanical properties. The project will position Australia as a leader in this newly developing medical imaging technology, with significant potential for commercialisation.Read moreRead less

This project aims to design and implement a lightweight security framework for Low Power Wide Area Networks (LPWAN). Smart cities are estimated to have a worldwide market value of US$1.5 trillion by 2020, and LPWAN will provide connectivity to 90% of low bandwidth, smart city applications such as smart metres and smart buildings. Many of these applications are deployed in mission-critical infrastructure such as airport, train station, hospital and government campuses, which have strong security requirements. Before the ubiquitous deployment of such new technology, a strong security framework needs to be developed and implemented to minimise enormous economic and social consequences of future malicious attacks to LPWAN.Read moreRead less
