"Wire is not dead": Wired-backscatter Communication for Breakage Detection in Electric Fences. |
Abstract | ||
|---|---|---|
Electric fences protect human habitats from elephant attacks in rural Sri Lanka. Maintaining such fences and in particular detecting breakages is tedious and expensive. In this paper we design a low-cost system to detect breakages in fences. We use low-power, low-cost sensor nodes deployed along the fence wires to detect the breakages. The nodes are assigned with unique node identifiers that indicate their location on the fence. The sensor nodes modulate the high voltage pulse on the fence to transmit their node ID to a master co-located with the fence-energizer. The absence of a node ID indicates a breakage at a location between the energizer and that node. Since the detector nodes use the fence-pulse, generated by the fence-energizer, as the carrier they consume only a small amount of energy. We show that this backscatter-like communication through the high-voltage fence wire reduces the implementation and running cost of breakage detection-enabled electric fences significantly. |
