PLC Availability Scheme

Ensuring availability in Power Line Communication (PLC) networks is paramount to maintaining uninterrupted communication, especially given their critical role in critical infrastructure. While most of the existing research has been dedicated to ensuring the availability of these devices, there remains an overlooked area when it comes to Denial of Service (DoS) attacks. Current mechanisms might identify a jammer close to the target devices, yet such devices may encounter difficulties signaling interference under jamming conditions. On the other hand, when these systems are considerably remote from the jammer, detecting its presence becomes quite complicated. This chapter introduces a novel method for detecting the presence of a jammer in a PLC network, which serves to safeguard the availability of remote network equipment. The results of the proposed technique are able to locate a jammer with a probability exceeding \(0.99\) , even when it is positioned 75 m away.
