Cognitive Radio Technology: Increasing Spectral Efficiency of Wireless Communications. The radio spectrum is an expensive resource and normally requires licensed operation. Cognitive Radio has been proposed as a means of releasing large tracts of unused spectrum without causing interference to other users. It uses a combination of frequency agility and intelligence to identify unused spectrum for transmission. This study will evaluate the performance gains of such a system by developing a spect ....Cognitive Radio Technology: Increasing Spectral Efficiency of Wireless Communications. The radio spectrum is an expensive resource and normally requires licensed operation. Cognitive Radio has been proposed as a means of releasing large tracts of unused spectrum without causing interference to other users. It uses a combination of frequency agility and intelligence to identify unused spectrum for transmission. This study will evaluate the performance gains of such a system by developing a spectrum occupancy data base to test a variety of radio access strategies. Cognitive Radio is particularly suited to providing low cost broadband access to remote, rural and city fringe dwellings.Read moreRead less
Modelling, Measurement and Control of the Internet. The demands made of modern high-speed data networks, such as those that make up the Internet, are increasing rapidly in terms of both the quantity and quality of service required.
So that these demands can be satisfied, it is necessary that network operators, or even the network itself, take measurements and make control decisions. Depending on the service, there is a need to do this over very short timescales (fractions of a second), or lon ....Modelling, Measurement and Control of the Internet. The demands made of modern high-speed data networks, such as those that make up the Internet, are increasing rapidly in terms of both the quantity and quality of service required.
So that these demands can be satisfied, it is necessary that network operators, or even the network itself, take measurements and make control decisions. Depending on the service, there is a need to do this over very short timescales (fractions of a second), or longer
timescales (minutes or even weeks).
By developing innovative mathematical models of network behaviour,
this project will deliver improved methods for measurement and
control of the Internet.Read moreRead less

The provision of Broadband Internet services to the home also requires extremely-fast 'backbone' connections between cities to carry the additional traffic demands.
In a previous project funded by the ARC, Monash researchers developed Optical-Orthogonal Frequency Division Multiplexing (OFDM) technology to increase the information-carrying capacity of optical fibers simply by plugging in new circuit boards at exchanges. This is now being commercialised by a new Australian company, to considerable international acclaim. This project aims to provide the next generation of this technology, which will support even faster internet and will ensure the long-term future of Australian telecommunications manufacturing.
