The emerging Wavelength-Division-Multiplexing (WDM) optical network is a promising candidate for next-generation Internet, which provides enormous bandwidth and fast connectivity. Multicast in WDM networks is a fundamental problem which has wide applications including teleconferencing, entertainment distribution, etc. In this project we investigate the multicast and constraint multicast problems in both single-hop and multi-hop WDM networks by studying their computational complexities and devising scalable, high-quality approximation algorithms for them. The developed algorithms significantly improve the network performance and scalability, and the innovative approaches and algorithm techniques developed in this project are also applicable to other routing problems.Read moreRead less
VHF wireless technologies for last-mile Internet access in regional Australia. One of Australia's most vexing social issues is the provision of the last-mile Internet connection in regional Australia. The BushLAN team will solve this problem at minimal cost by developing a cellular wireless local area network operating on the TV band I channels (45-70 MHz). We will do this by developing a wireless modem whose design takes into account the properties of radio propagation in the Australian enviro ....VHF wireless technologies for last-mile Internet access in regional Australia. One of Australia's most vexing social issues is the provision of the last-mile Internet connection in regional Australia. The BushLAN team will solve this problem at minimal cost by developing a cellular wireless local area network operating on the TV band I channels (45-70 MHz). We will do this by developing a wireless modem whose design takes into account the properties of radio propagation in the Australian environment. We are collaborating with Internet service providers in regional Australia to trial systems currently being developed. In the process we will develop a new technology that will provide training for young engineers.Read moreRead less

Summary
Infrastructure for wireless Internet technology development for rural Australia. Three nodes of a low-power, very-high frequency digital wireless network will be installed at two locations in the Australian National University and one location at the University of Canberra. An additional node will then be located a further distance away (> 50 kms) in the ACT. This network will allow the development of novel technology for moderate speed (>100 kbps) non-line of sight wireless Internet access o ....Infrastructure for wireless Internet technology development for rural Australia. Three nodes of a low-power, very-high frequency digital wireless network will be installed at two locations in the Australian National University and one location at the University of Canberra. An additional node will then be located a further distance away (> 50 kms) in the ACT. This network will allow the development of novel technology for moderate speed (>100 kbps) non-line of sight wireless Internet access over ranges of 3-100 km for potential use by regional Australian Internet providers. The network will also catalyse research and training in wireless communication technology , digital signal processing, and computer networking.Read moreRead less
