Adaptive sliding mode congestion control for DiffServ Network

Abstract

This paper is about the application of adaptive sliding mode control to solving congestion problem for DiffServ Network. A nonlinear fluid flow model which is transformed into a parametric strict feedback form is used to analyze and control. Backstepping design procedure is applied, which leads to a new adaptive sliding mode controller. And by using the adaptive sliding mode controller, we achieve buffer queue length regulation against model uncertainties and disturbances. The simulation results show that the proposed control system is robust to unknown nonlinearities and disturbances.
