QoS-LI: QoS Loss Inference in Disadvantaged Networks

Abstract

-Quality of Service (QoS) of disadvantaged networks is usually considered from a purely network standpoint in existing works. Adversarial intervention in such networks is not analyzed, nor is it possible to infer if a QoS loss is benign or otherwise. In this work, we analyze the nature of a QoS loss between a remote system and a backend service infrastructure connected over a disadvantaged satellite network. We present a game theoretic framework to infer if a QoS loss is due to benign or malicious factors. An attack on the backend system (DDoS attack) or on the transmitting station (RF Jamming) is considered to be a malicious factor, while a statistical network variation due to random noise is considered to be a benign factor. We then present the implementation of the game theoretic framework to the satellite network, and verify the validity of the idea through simulations in OPNET.
