The usage of link quality based routing metrics significantly improves the quality of the chosen paths and by that the performance of the network. But, attackers may try to exploit link qualities for their purposes. Especially in tactical multi-hop networks, routing may fall prey to an attacker. Such routing attacks are a serious threat to communication. TOGBAD is a centralised approach, using topology graphs to detect routing attacks. In this paper, The authors enhance TOGBAD with the capability to detect fake link qualities. They use a Challenge/Response method to estimate the link qualities in the network. Based on this, they perform plausibility checks for the link qualities propagated by the nodes in the network.
