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.
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.

A rapidly growing demand for fast wireless services calls for wideband communication systems with wideband antennas, which are compact, aesthetically appealing and inexpensive, yet have good performance. With novel concepts, this project aims to produce a new class of antennas that deliver impressive performance (bandwidth and gain) while taking up a dramatically reduced area in a way that was impossible before, increasing a figure-of-merit to up to seven times the state-of-the-art. Their planar geometry and simplicity lead to low cost. This is expected to create new knowledge, design methods and examples, prototypes, test results and guidelines required to design, optimise and make these versatile antennas for emerging robust broadband wireless systems.Read moreRead less

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
Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by ....Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by modifying the levels of road and rail crossings and providing guard rails in the recesses of these modified level crossings. The theories are intended be developed using nonlinear dynamic computational methods and laboratory experiments. The outcomes are expected to enable reduction in the severity of level crossing accidents and hence save lives and costs of derailment.Read moreRead less
