Expendable and Distributed Measurement Scheme for Acquisition of Naturally Sparse Events

Abstract

A common reason for electronic measurement anomaly is the inadvertent rise in ground potential with respect to measurement ground. The ground potential rise happens during current leakage to ground from lightning or from power grid and leads to catastrophic failure unless appropriate preventive action is taken to isolate the sensitive measurement systems. A networked system for acquisition and transmission of ground potential measurements to data monitoring station is presented here. The system is aimed to implement using low-cost IoT devices with limited resources since these units are planned to be expendable. The limited processing power of such devices is not sufficient to run high efficient computation intensive routing algorithms. A lightweight routing algorithm for this purpose is proposed here. The discussion on reliability of such systems is also presented. The multipath route discovery strategy presented here reconfigures the network to an optimal configuration with respect to energy dissipation and node distribution.
