Association Graph Based Jamming Detection in Multi-Hop Wireless Networks

Jamming attacks have been a great challenge for the researchers since they can severely damage the Quality of Service (QoS) of Multi-Hop Wireless Networks (MHWNs). Therefore, how to detect and distinguish multiple jamming attacks and thus to restore network service has been a hot topic in recent years. Note that different jamming attacks will cause different network status changes in MHWN. Based on this observation, a jamming detection algorithm based on association graph is put forward in this paper. The proposed algorithm consists of two phases, i.e. learning and detection phases. At the learning phase, with different symptoms are extracted through learning from various samples collected from both jamming and jamming-free scenarios, symptom-attack graph is built. Then, at the detection phase, the built symptom-attack association graph is adopted to detect the jamming attacks that lead to the observed symptoms by some particular network node. A series of simulation experiments on NS3 validated that the proposed method can efficiently detect and classify the typical jamming attacks, such as reactive, random and constant jamming attacks.
