Abstract

Fault diagnosis is one of the most important and demand-
able issues of the network. It makes the networks reliable and robust to
operate in the normal way to handle almost all types of faults or failures.
Additionally, it helps sensor nodes to work smoothly and efficiently till
the end of their lifetime. This short survey paper not only presents a clear
picture of the recent proposed techniques, but also draws comparisons
and contrasts among them to diagnose the potential faults. In addition,
it proposes some potential future-work directions which would lead to
open new research directions in the field of fault diagnosis.
