Abstract

This paper is concerned with the design of improved AQM control schemes by means of an appropriate reduction method for time-delay systems. The aim is to stabilize the delay differential equations model of TCP (transmission control protocol) behavior. A robust observer is introduced to estimate online the transmission window resulting in a window-based congestion control scheme. The robust stability and dynamic behavior in the presence of network parameter uncertainties is validated and tested through numerical simulations on a single bottleneck.
