Cross-layer optimisation for topology design of wireless multicast networks via network coding (2014)
Presentation / Conference Contribution
Vien, Q. T., Tu, W., Nguyen, H. X., & Trestian, R. (2014, September). Cross-layer optimisation for topology design of wireless multicast networks via network coding. Presented at Proceedings Conference on Local Computer Networks LCN, Edmonton, Canada

One of the main challenges towards reliable multicast transmissions over wireless networks is the dynamics of the wireless links (e.g. wireless errors, fading, interference, collisions, etc.) that can cause retransmissions overhead over the limited a...

A multi-rate multi-channel multicast algorithm in wireless mesh networks (2014)
Presentation / Conference Contribution
Tu, W. (2014, September). A multi-rate multi-channel multicast algorithm in wireless mesh networks. Presented at Proceedings Conference on Local Computer Networks LCN, Edmonton, Canada

Devices in wireless mesh networks can operate on multiple channels and automatically adjust their transmission rates for the occupied channels. This paper shows how to improve performance-guaranteed multicasting transmission coverage for wireless mul...

On the energy-delay tradeoff and relay positioning of wireless butterfly networks (2014)
Journal Article
Vien, Q. T., Nguyen, H. X., Stewart, B. G., Choi, J., & Tu, W. (2015). On the energy-delay tradeoff and relay positioning of wireless butterfly networks. IEEE Transactions on Vehicular Technology, 64(1), 159-172. https://doi.org/10.1109/TVT.2014.2321229

This paper considers energy-delay tradeoff (EDT) of data transmission in wireless-network-coded butterfly networks (WNCBNs) where two sources convey their data to two destinations with the assistance of a relay employing either physical-layer network...

A generalization of the Buckley-Osthus model for web graphs (2014)
Journal Article
Yan, Y., Tu, W., Grout, V., & Excell, P. (2014). A generalization of the Buckley-Osthus model for web graphs. Discrete Mathematics, 320(1), 73-86. https://doi.org/10.1016/j.disc.2013.12.008

We generalize the web graph models of Buckley and Osthus (2004) and Wu et al. (2009) to a directed version in the manner of Bollobás et al. (2003) and Cooper and Frieze (2003). The graph evolution process is a mixture of five steps. The degree distri... Read More about A generalization of the Buckley-Osthus model for web graphs.
