Sensor fault detection and isolation for smart irrigation wireless sensor network based on parity space

<p>In the recent years, wireless sensor network technology (WSN) has been widely adopted in precision agriculture for determining needs of soil term water by monitoring some environmental parameters. To do this, WSN is constructed using several nodes; these small sensing devices are prone to failure and may produce erroneous measurements. ensure good management freshwater, service quality necessary. avoid degradation service, detection faulty required. In this paper, a fault isolation (FDI) algorithm derived from parity space approach based on direct redundancy proposed toward detecting isolating WSN. laboratory experiments, FDI proved its effectiveness.</p>
