MSc Position in Quality of Service for Multi-player Games over 802.11 Wireless

Applications are invited by well-qualified applicants for an MSc position in the area of quality of service provisioning in 802.11 wireless networks to support multi-player games.

Online gaming is one of the most rapidly increasing sources of traffic in the modern internet. A key feature of multi-player games is the requirement for low latency to allow real-time interaction between players. A second major trend is the increasing use of an 802.11 wireless link as the last hop in homes. The recent 802.11e standard allows traffic classes to be distinguished and prioritised differently. The networking group at the Hamilton Institute has been at the forefront of 802.11e development, including development of the first public 802.11e testbed and of some of the first accurate analytic models capturing the behaviour of real traffic over 802.11e links. This project will build on this to investigate the use of 802.11e (and 802.11n) functionality to meet the quality of service requirements of online games over wireless links. This will require meeting a number of key challenges, including not only the tight delay requirements of games traffic but also 802.11 MAC related issues. The project will also explore linking of 802.11 MAC level resource allocation decisions to higher level policy-driven network management.

Applicants should have good numerate and analytic skills and an understanding of IP networking. Some familiarity with the configuration and use of Linux or BSD systems and of scripting and programming will be helpful since the project wll involve demonstration of developed techniques on our 802.11 wireless testbed.

The Hamilton Institute is committed to research excellence. This post offers an exciting opportunity for successful candidates to tackle fundamental research problems within a stimulating multi-disciplinary research environment with state of the art facilities and strong links to the international research community.
