A Comprehensive Review on Fault Detection For Wireless Sensor Networks

Wireless sensor networks (WSNs) exhibit a diverse cyber-physical nature, rendering them susceptible to various faults with potential consequences for reliability, economics, and safety. However, the deployment of sensors in challenging and unattended environments for prolonged durations poses significant challenges in delivering high-quality services. Consequently, the occurrence of sensor malfunctions, and communication breakdowns becomes inevitable. Therefore, the development of effective fault detection (FD) methods is crucial to ensure the provision of high-caliber services. In this paper, we investigate several FD strategies and propose a novel taxonomy that incorporates innovative approaches to FD. Through qualitative analysis, we carefully select a set of techniques, which are subsequently subjected to quantitative evaluation. Moreover, we comprehensively review the limitations, advantages, and potential research directions pertaining to FD in WSNs.
