Sliding mode congestion control for DiffServ Networks

A nonlinear fluid flow model is used in this paper to analyze and control DiffServ Networks. The controller design is based on the integrated dynamic congestion control strategy. In this paper different second order sliding mode controllers are proposed to solve the infinite switching problem. The same as standard sliding mode control, second order sliding mode technique is also robust to model uncertainties and disturbances, meanwhile overcome the inherent chattering problem which is more acceptable in application. The performance of the control algorithms are verified by the simulation results.
