A new sliding mode controller for TCP congestion control

In this paper a new controller for congestion problem in TCP networks has been proposed. Sliding mode controller is robust against modeling uncertainties and disturbances. In sliding mode control states should be reached a predefined surface (sliding surface), in a limited time and remain the same surface over time. Moving on the sliding surface is independent of the uncertainties, so this technique is one method of robust control. After applying controller to system, stability of the system with controller has been proven by Lyapunov stability criteria. Simulation result shows the efficiency of the sliding mode controller in different scenarios.
