PACKET TRAFFIC in NETWORKS
Mathematics Research Centre and Telecoms Group, QMW
The
Mathematics Research Centre and the Telecoms Group (Department of Electronic Engineering) has a Joint Research Group in the study of "Packet traffic in networks". The group aims to use non-linear dynamics to model transmission and queueing behaviour with the aim of providing control mechanisms for performance of networks.PERSONNEL
Currently the group has the following staff involved in the initiative-
Prof. David Arrowsmith (MRC)
Dr Basia Bogacka (MRC)
Prof John Griffiths (Research Fellow, TG)
Dr Raul Mondragon (Research Fellow, MRC)
Dr Jonathan Pitts (TG)
Dr John Schormans (TG)
The Joint Research Group has three post-graduate students:
Martino Barenco (MRC) - Control of packet traffic in networks
Ashis Joshi (TG) - Modelling of packet traffic characteristics using chaotic maps
Markus Keogh-Brown (MRC) - Statistics of web-caching
Two of the students are supported by EPSRC and one is supported by a College Studentship.
BT CASE AWARDS
All three students are further supported by BT (British Telecom) with CASE supplements. Their projects involve liaison with members of the BT Laboratories at Martlesham, Ipswich. Dr Ian Marshall and Dr Sverrir Olafsson are the primary sponsors of the research.
