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

Nassima Jihani, Mohammed Nabil Kabbaj, Mohammed Benbrahim


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