This paper proposes a new method for distributed wire diagnosis using reflectometry. It not only uses the reflected part of the test signal to extract information about the fault position, but it also investigates the transmitted part to enable sensors communication. The major novelty is to inject a signal carrying additional information about the fault position as a test signal using Orthogonal Multi-Tone Time Domain Reflectometry (OMTDR) method. While the reflected signal permits to determine the fault position at time , the transmitted one sends the fault position at time (−1) to the master sensor. Finally, the latter takes the location decision based on the information gathered from its slaves. This removing location ambiguities in branched networks. Time Division Multiple Access (TDMA) is used to avoid noise interference.
