Sensing and Communications for Tactical Radio: Mapping the RF Weather. This project investigates sensing, localisation and communication strategies to improve the performance of modern tactical radio networks. Such networks face all of the well-known design challenges of mobile ad-hoc networks (MANETs) but with added complication of a contested and adversarial operating environment. By exploiting the power of radio nodes to sense the radio spectrum, as well as to communicate over it, a distribut ....Sensing and Communications for Tactical Radio: Mapping the RF Weather. This project investigates sensing, localisation and communication strategies to improve the performance of modern tactical radio networks. Such networks face all of the well-known design challenges of mobile ad-hoc networks (MANETs) but with added complication of a contested and adversarial operating environment. By exploiting the power of radio nodes to sense the radio spectrum, as well as to communicate over it, a distributed network of nodes can create a detailed picture of the surrounding radio-frequency (RF) environment: the nodes can work together to map the “RF weather”. In this project we will design advanced sensing and localisation methods to accurately map the RF spectrum, and then exploit this map in communication system design.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. In most cases it is not the lac ....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. 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
Adaptive Multi-user Detectors for Mobile Space-Time Communications Systems over Time Variable Fading Channels. High capacity wire-line internet access (~ 1 Mbit/s) is available through existing telephone lines or through the cable TV infrastructure. The need to have the same quality wireless and mobile internet access is becoming evident. The full deployment of the mobile internet might be delayed due to the low capacity of existing cellular mobile communications systems. This research project w ....Adaptive Multi-user Detectors for Mobile Space-Time Communications Systems over Time Variable Fading Channels. High capacity wire-line internet access (~ 1 Mbit/s) is available through existing telephone lines or through the cable TV infrastructure. The need to have the same quality wireless and mobile internet access is becoming evident. The full deployment of the mobile internet might be delayed due to the low capacity of existing cellular mobile communications systems. This research project will contribute to the understanding of fundamental capacity limitations of the mobile communications concept over communication channels that vary with time. The outcomes of the project will suggest possible solutions to the capacity limitations.Read moreRead less

What to do about WiFi Congestion? New methods for dense, wireless networks. This project aims to design and analyse new protocols for (wireless) WiFi networks. The demand on current WiFi networks is escalating at a tremendous rate. WiFi uses the unlicensed radio spectrum, so innovation can occur more easily over WiFi than over carrier-owned networks. WiFi also provides data offloading from severely congested cellular wireless networks. Unfortunately, the current WiFi multiple access protocols we ....What to do about WiFi Congestion? New methods for dense, wireless networks. This project aims to design and analyse new protocols for (wireless) WiFi networks. The demand on current WiFi networks is escalating at a tremendous rate. WiFi uses the unlicensed radio spectrum, so innovation can occur more easily over WiFi than over carrier-owned networks. WiFi also provides data offloading from severely congested cellular wireless networks. Unfortunately, the current WiFi multiple access protocols were not designed to handle closely packed WiFi networks and the resulting interference. This project takes a novel approach to develop algorithms that are much more robust to interference, and which use simple, distributed mechanisms to feed channel state information back from the receiver to the transmitter to maximise performance.Read moreRead less
