[Nets-seminars] UCL EE seminar

[Richard G. Clegg]

The first seminar of this term is today, Friday 4th October at 16:00.  
It will take place in the Roberts building (the main Electronic 
Engineering building on campus) room 905 (Sir Eric Ash room).  You need 
a staff card to enter so if you are coming from outside UCL please let 
me know so I ensure that you can get in.  Our speaker is Marwan Fayed 
from Stirling.

Title:  Towards Position-based Routing for Mobile Environments

Abstract: Despite its simplicity there exists, as yet, no position-based 
routing that is suitable for dynamic networks. This, despite being 
well-studied, simple (in principle), and requiring little-to-no 
overhead. In this talk I shall present a 'first principles' 
investigation of the forwarding component according to left- or 
right-hand rule (LHR) in order to understand its limitations and 
obstacles. We find there are only five (5) possible intersecting 
configurations. Surprisingly only one (1) of these configurations 
defeats LHR, and even then only under a strict set of circumstances that 
rarely appear.

I shall then use this analysis, and our solutions so far, to suggest 
that it may be time to revisit traditional notions of path-finding 
guarantees in environments where non-routing elements are the dominant 
causes of loss.
