Second order sliding mode observer for anomaly detection in TCP networks: From theory to practice

We investigate the design of a second order sliding mode observer for detecting anomalies in TCP networks. More precisely, based on a fluid model of TCP network, we aim at designing an observer, whose state variables reconstruct some external signals which perturb the nominal behavior of TCP. The proposed methodology is validated via NS-2 simulations. Finally, an experimental setup is proposed to show the effectiveness of our approach.
