Study of TCP congestion control algorithm based on fuzzy tuning sliding mode surface

An congestion control scheme based on fuzzy adaptive sliding mode control is designed.It can improve the queue tracking behavior by fuzzy tuning the sliding surface,the proposes method have strong robust against network modeling uncertainties,network parameters time varying fluctuations and non-TCP sessions disturbances.Simulation results demonstrate that it can lead to the convergence of the queue length to the desired value quickly and maintain the oscillation small.The results also show that the scheme is very robust to disturbance under various network conditions and outperforms fuzzy control and variable structure control significantly.
