MoN17: Seventeenth Mathematics of Networks meeting

Understanding user contention and its effects on resource allocation in heterogeneous networks – Dr Glenford Mapp (Middlesex)

User contention in networks causes congestion, delays and packet/data loss. It also affects the ability of users to make use of network resources. Thus having mathematical models that can look at user contention in detail is a key factor in optimizing network resources. This is particularly true in a heterogeneous environment where users are using vertical handover techniques to maintain seamless communication.

This talk looks at probabilistic mathematical models that allow us to examine user contention in different types of networks. Starting with pure ALOHA, it also looks at mobile and vehicular networks. The work shows that using proactive allocation techniques can optimise the use of networking resources in heterogeneous environments.

Bio: Dr. Glenford Mapp received his BSc (First Class Honours) from the University of the West Indies in 1982, a MEng (Distinction in Thesis) from Carleton University in Ottawa, Canada in 1985 and a PhD from the Computer Laboratory, University of Cambridge in 1992. He then worked at AT&T Cambridge Laboratories for ten years before joining Middlesex University in London in 2003, where he is currently an Associate Professor. He was also a Visiting Research Fellow at the Computer Laboratory between 2003 and 2010 where he worked on several projects. His primary expertise is in the development of new technologies for mobile and distributed systems, vehicular networks and Smart City infrastructure. He has published over 100 papers in refereed journals and conferences
