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

This project will fundamentally characterise and optimize information gathering, dissemination, and communication capacities of airborne base stations to enable low latency communications in rural and remote areas. New technologies such as precision farming, safe remote equipment operation in mining, and wide area surveillance and security, require low latency communications that are an order of magnitude beyond what is currently available from satellite links. The expected outcome will be radically new base station deployment and flight path planning, and data transmission technologies. These will unlock new application technologies by enabling secure wide-spread communications coverage, delivering economic benefits to remote Australia.Read moreRead less
Easing the Squeeze: Dynamic and Distributed Resource Allocation with Cognitive Radio. The radio spectrum is a scarce and valuable natural resource which is being squeezed by the rapid growth in wireless communications. Cognitive radios make efficient use of radio spectrum by dynamically reusing frequencies. This requires cognitive radios to sense the local environment and to control the interference caused to existing users of the spectrum. This project will design novel dynamic and distributed ....Easing the Squeeze: Dynamic and Distributed Resource Allocation with Cognitive Radio. The radio spectrum is a scarce and valuable natural resource which is being squeezed by the rapid growth in wireless communications. Cognitive radios make efficient use of radio spectrum by dynamically reusing frequencies. This requires cognitive radios to sense the local environment and to control the interference caused to existing users of the spectrum. This project will design novel dynamic and distributed resource allocation algorithms for cognitive radios in order to significantly improve their performance using techniques from extreme value theory, game theory and mechanism design and large random matrix theory.

Novel Techniques for Uncoordinated Massive Access in the Internet of Things. The IoT (internet of things) is the backbone of intelligent transportation, healthcare, energy and smart home systems. To accommodate the exponentially increasing number of IoT devices, a dramatic paradigm shift towards non-orthogonal uncoordinated (grant-free) massive access is underway, where devices transmit data opportunistically over shared channel resources.

The IoT (internet of things) is the backbone of intelligent transportation, healthcare, energy and smart home systems. To accommodate the exponentially increasing number of IoT devices, a dramatic paradigm shift towards non-orthogonal uncoordinated (grant-free) massive access is underway, where devices transmit data opportunistically over shared channel resources. This project aims to develop new receivers for such uncoordinated massive access, where the receivers will be trained to identify transmitting devices, recover their data, and resolve any collisions.
