Research Topic

I am a PhD student in Hamilton Institute. My current main research subject is on Wireless Networks, especially 802.11 protocols for Real-timed Multiplayer Networked Games. It includes performance improvement of network which is mainly on the MAC layer with resource allocation flavour, mathematically model of networked games, networked games traffic measurement over 802.11 networks testbed and improvement of 802.11 for supporting real-time applications (such as games). My research interests also include queuing theory, game theory and their applications on networks and networked games. I also do some research on error-correction coding, especially LDPC codes as my past research subject and interest now. I am also interested in theoretical Physics such as theory of relativities and quantum mechanics etc.


Hanghang Qi was born in 1982 in Jinzhou, Liaoning, China. In 2004, he received bachelor degree in Electrical Engineering from Shanghai Jiaotong University, China and then spent 1 year as a CPU test module engineer in Intel Shanghai. In 2006, he received master degree with distinction in University of Edinburg. In 2008, he joined wireless communication group of Hamilton Institute (, National University of Ireland, Maynooth.
