Abstract Wireless Sensor Network (WSN) is used in different research areas such as military,
industry, healthcare, agriculture, Internet of Things (IoT), transportation, and smart cities. The …

This paper covers the basics of fault diagnosis in wireless sensor networks, as well as fault
diagnosis terminology, sensor fault classification, causes and effects, and fault diagnosis …

Fault diagnosis has been considered as a very challenging problem in wireless sensor
network (WSN) research. Faulty nodes having different behavior such as hard, soft …

Nowadays, our lives have become increasingly inseparable from the services facilitated by
telecommunication networks. Disruption of this service may result in a significant detrimental …

The faults in wireless sensor network are classified according to the underlying causes,
behavior, and persistence with respect to the observation time. Due to underlying causes …

Sensor devices in wireless sensor networks are vulnerable to faults during their operation in
unmonitored and hazardous environments. Though various methods have been proposed …

Wireless sensor network (WSN) is a collection of sensor devices, which collects information
from the environment and sends to the base station by single-hop or multi-hop …

Wireless sensor networks (WSNs) are ad hoc networks that consist of tiny sensor nodes
deployed in the sensed environment to monitor the natural phenomenon and send the …

Relay node placement preserving coverage and connectivity is an important problem for the
deployment of a fault tolerant two tier wireless sensor network (WSN). In this paper, we …

In this work, a real time soft fault diagnosis model is proposed for wireless sensor networks
(WSNs) using particle swarm optimization (PSO) based classification approach. The …
