Design of Wireless sensor and communication networks with fixed and mobile nodes. Wireless sensor and communication networks with fixed and mobile nodes are rapidly becoming essential technologies for hostile environmental monitoring, battlefield surveillance and precision agriculture. However, due to the complexities associated with interconnected design issues involving sensors, autonomous vehicles and communication protocols, even very simple networks have proven to be difficult to design.

Wireless sensor and communication networks with fixed and mobile nodes are rapidly becoming essential technologies for hostile environmental monitoring, battlefield surveillance and precision agriculture. However, due to the complexities associated with interconnected design issues involving sensors, autonomous vehicles and communication protocols, even very simple networks have proven to be difficult to design. This project proposes to intelligently employ higher capabilities of mobile nodes and develop methods for rapid deployment, maintenance and routing that are aware of location, energy, and security. The outcomes of this project will form the basis for design of intelligent wireless networks for defence and civilian applications.Read moreRead less
Adaptive Modulation For OFDM Signals. The sub band Signal To Noise Ratio in an OFDM communications channel varies by as much as 30 dB. In order to optimise the bandwidth efficiency of OFDM signalling it is desirable to adapt the chosen modulation technique such as M-ary QAM to the SNR available in sub bands. In this way high quality channels transmit the highest bit rates, whilst low quality channels accommodate the lowest bit rates. The net result is that the capacity of the communications link ....Adaptive Modulation For OFDM Signals.

Optimal Waveform Design and Compensation Techniques for Non Linear Communication Channels. Distortion effects in satellite amplifiers have a serious impact upon communication system performance, for example, by increasing the error rates.
The research study we are proposing involves analysing these distortion causing non linear effects and designing techniques to compensate for them.

Distortion effects in satellite amplifiers have a serious impact upon communication system performance, for example, by increasing the error rates.
The research study we are proposing involves analysing these distortion causing non linear effects and designing techniques to compensate for them. Although we are initially interested in the nonlinear satellite channel, we intend the results to be extended to other difficult nonlinear channels such as will be present in future 3G and 4G mobile communication systems.
The proposed research will place Australia at the forefront of cutting edge Information Technology and Communications research.

Algorithmics for Extremely Mobile Wireless Networks. Existing wireless network protocols need stringent conditions to be effective. These conditions are rarely met for concrete applications such as Defence, Disaster-Relief, Search-and-Rescue. All these cannot rely on existing infrastructure, and often require high mobility. This is crucial in the case of Australia which cannot rely on complete network coverage of its lands and seas. This project will develop new wireless protocols for applicati ....Algorithmics for Extremely Mobile Wireless Networks. Existing wireless network protocols need stringent conditions to be effective. These conditions are rarely met for concrete applications such as Defence, Disaster-Relief, Search-and-Rescue. All these cannot rely on existing infrastructure, and often require high mobility. This is crucial in the case of Australia which cannot rely on complete network coverage of its lands and seas. This project will develop new wireless protocols for applications requiring extreme mobility. It will increase Australia's control of this, now ubiquitous, technology thus rendering Australia a key player in this field.Read moreRead less
Markov Field Theory applied to Sensor Networks Analysis and Design. Ad hoc and sensor networks have a wide range of applications in defence, emergency services and agriculture because they do not require telecommunications infrastructure such as base stations or access points, hence are relatively easy to deploy in harsh environments.

This project aims at improving the theoretical understanding of sensor and ad hoc networks, which enable improvements in performance in such networks. Australian defence industry and emergency services will benefit from this research by gaining access to improved ad hoc communications networks. The agricultural sector will also benefit from the improved sensor networks in applications such as monitoring soil conditions, stock and crop levels. Read moreRead less
Advances in the Verification of Communication Protocols. Australia's economy is becoming increasingly dependent on many complex distributed systems.

Australia's economy is becoming increasingly dependent on many complex distributed systems. Some important examples are the Internet, electronic commerce, financial networks, transportation systems, health care networks, telecommunication networks, defence systems, intelligent manufacturing systems and organisational workflow management systems. Failure in these systems can result in serious financial loss (in banking applications) and loss of life or serious accidents in safety critical areas (medical, transport and defence applications). It is thus of utmost importance that distributed systems are designed correctly. This project aims to advance the state of the art in verifying that distributed systems will work correctly.Read moreRead less

Target Identification with Ultra-Wideband Polarimetric Radar. Radar reflecting objects resonate when electromagnetically and appropriately excited. These resonances can be extracted from the returned radar signal and used to identify the object. A simile is identifying a tuning fork from its sound rather than its image.
