I will discuss recent work in two related areas in 802.11 based on empirical observations and robust heuristics. The first concerns available bandwidth estimation, and the second rate control algorithms. The link between the two is the need to reliably isolate physical packet error from total packet error, which is frequently dominated by congestion.
Darryl Veitch completed a BSc.~Hons.~at Monash University, Australia (1985) and a mathematics Ph.D.~from Cambridge, England (1990). He worked at TRL (Telstra, Melbourne), CNET (France Telecom, Paris), KTH (Stockholm), INRIA (Sophia Antipolis, France), Bellcore (New Jersey), RMIT (Melbourne) and EMUlab and CUBIN at The University of Melbourne, where he is a Principal Research Fellow. His research interests include traffic modelling, parameter estimation, active measurement, traffic sampling, and clock synchronisation.
