Abstract
- One of the main threats to wireless multi-hop networks is Denial-of-Service (DoS), which either aims to bring down network performance or tends to rapidly consume resources of a particular node. Different from traditional DoS which provokes sudden changes in network traffic, routing protocol misuse that exploits vulnerabilities of routing protocols would reduce the overall performance without triggering alarms from existing detection methods based on rapid changes in network traffic. In order to overcome the weakness of traffic burst based detection methods, this paper proposes an enhanced anomaly detection and restoration scheme to defeat low-rate DoS launched by rogue nodes. Meanwhile, an exponential backoff restoration (EBR) algorithm is proposed to reduce performance degradation. Simulation results validate that the proposed scheme is able to maintain the overall network performance under low-rate DoS.
