Abstract :

Wireless sensor networks (WSNs) consist of several sensor nodes that may be deployed in relatively harsh and complex environments. Regarding cost, sensor nodes always adopt relatively cheap chips, which make these nodes error-prone in the course of their operation. Various natural factors, as well as electromagnetic interference, could also influence the performance of the WSNs. When sensor nodes become faulty, they may die which means they cannot send data to other members in the wireless network, or they may be alive but gives incorrect data or they may be unstable jumping between the normal state and faulty state. Many studies have focused on fault diagnosis to improve the quality of data, shorten response time, strengthen network security, and prolong network lifespan. This paper presented the study on wireless sensor networks with challenges and their application.
