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
Large Scale Complex Multiagent Systems : Control Methodologies and Information Architectures. Future military operations are likely to involve increasing use of unmanned vehicles, airborne, underwater or on land. In some cases there will be very large formations.

Much of the same methodology is applicable to the construction and operation of large scale sensor networks, identified by some comm ....Large Scale Complex Multiagent Systems : Control Methodologies and Information Architectures. Future military operations are likely to involve increasing use of unmanned vehicles, airborne, underwater or on land. In some cases there will be very large formations. This research will develop methodologies which allow formations of unmanned vehicles to be configured. Much of the same methodology is applicable to the construction and operation of large scale sensor networks, identified by some commentators as one of the most important technologies of the 21st century. They comprise large numbers of low cost networked sensors and will increasingly find application in security, agricultural and environmental monitoring.Read moreRead less
Optimising throughput and Delay in network coded systems. This project addresses one main disadvantage of network coding: decoding delay. By solving this issue, we will unlock the true potential of network coding: delivery of high data rates in wireless and wireline networks. This will make network coding an attractive choice for live video streaming and mission-critical delay-sensitive applications.
Optimum cross-layer design in wireless communication systems with channel uncertainty. For wireless communications to be part of Australia's information delivery infrastructure, including the National Broadband Network, requires improvements in reliability, speed and cost effectiveness over current technologies. The assembled world class research team has the objective to develop advanced design techniques to meet this challenge.
Network Intrusion Detection via Machine Learning. Computer security is an increasingly important, yet complex task. It
takes significant skills to configure systems properly such that they
are safe from malicious attacks.
The proposed project aims at designing automatic systems which are
able to adapt to an existing network configuration and which detect
novel and unusual events. For this purpose we will use modern machine

are safe from malicious attacks.
The proposed project aims at designing automatic systems which are
able to adapt to an existing network configuration and which detect
novel and unusual events. For this purpose we will use modern machine
learning techniques, mainly based on kernels. In particular, recently
developed algorithms to estimate the support of a distribution and
detect rare events will be employed in this context.
The project is in cooperation with Dr. Ralf Herbrich (Microsoft
Research, Cambridge).

Signal Processing for Reconfigurable Antennas – a Multidisciplinary Approach for Next Generation Wireless Communications. To satisfy the enormous demand for wireless applications with scarce radio spectrum, new technologies must be researched, developed, and then employed. Reconfigurable antennas, through morphing their physical structures with various switches, can adapt to the radio propagation environment, thereby increasing spectrum efficiency and power efficiency of wireless communications. ....Signal Processing for Reconfigurable Antennas – a Multidisciplinary Approach for Next Generation Wireless Communications.
