Power line network topology inference using Frequency Domain Reflectometry

Frequency Domain Reflectometry (FDR) is a technique that was proposed for fault detection in Digital Subscriber Line (DSL) cables. In this paper, we describe how FDR can be used to determine the topology of power line networks. To this end, we first infer distance information from the multiple signal reflections measured and processed with FDR. Then, we present an algorithm that uses these distance measurements to reconstruct the topology step by step operating on a network graph. Numerical results for sets of sample networks demonstrate the effectiveness of the proposed topology-inference approach.
