Intrusion detection in hierarchically structured wireless multi-hop networks

Security is one of the core challenges especially for ICT in disaster Recovery. Sensitive data is transmitted via insecure links. Furthermore, there may be competing interests. Thus, there is a high probability of disturbance or eavesdropping of communication. However, the hierarchical structure of networks in such scenarios can be exploited for security purposes. Based on this, we developed the Topology Graph based Anomaly Detection (TOGBAD). In this paper, we survey the basic approach as well as our three methodologies to detect sinkholes, wormholes, and fake link qualities.
