An Intrusion Detection System for Detecting Compromised Gateways in Clustered IoT Networks

It is well known that clustering IoT devices will help to alleviate the network scalability problem in IoT networks. However, clustering also provides an opportunity for an adversary to compromise a set of nodes by simply compromising their gateway. In such scenarios, one of the strategies available to an adversary to degrade the performance of a network is by corrupting the packets to be forwarded by the gateway. In this paper, a centralized detection system for detecting the presence of such a malicious gateway is proposed. The proposed system uses the packet drop probability as a means to monitor the gateways. An algorithm is presented to design the key parameters of the proposed system, and its performance is evaluated through extensive simulations.
