The Networks group was founded in 1987, and has since expanded greatly. We have an international reputation for excellence in bringing intelligence and performance assessment techniques to fixed and mobile communication networks. The group has a long-standing interdisciplinary collaboration with the School of Mathematical Sciences, supported by a succession of funded projects. This collaboration encompasses non-linear dynamics and experimental design, particularly as applied to optimising network measurement. We have been key players in many international collaborative projects, are active in joint teaching and research with Beijing University of Posts and Telecommunications, as well as a joint lab in Macao. The wireless research in the group is growing rapidly and current research now covers areas including cognitive radio, cooperative networks and MIMO, self-organising radio resource management, smart antennas, energy efficiency and capacity improvements, cross layer design, vehicular communication technologies, sensor networks and network security.
The group is active in many key areas of the current and future Internet, such as cloud, content delivery, and online social networks. Another specialty of the group is the use of mathematical formalisms and methodologies to model network behaviour, with significant contributions to queuing theory, topology and traffic modelling, accelerated simulation and measurement. The group actively exploits its intellectual property, whether as patents (e.g., jointly with major equipment vendors), or in spinout activity, such as Actual Experience Ltd, a software-based service business formed to commercialise research on the perceptual quality of networked applications.
