Wireless Sensor Networks (WSN) has gathered a considerable amount of attention because of its manifold application in various fields like defense, health monitoring, environment monitoring and disaster management. Though WSN has conquered the world due to its dynamicity still it is very much fault prone because of the reason that the sensors and actuators of the sensor node has to interact directly with the unpredictable environment, where it may be subjected to various physical, chemical and biological forces. To make a WSN more reliable and dependable various fault management systems are employed. Better the fault management higher is the reliability of the WSN. The aim of our paper is to review the functionality of some of the existing fault management systems including their architecture and present a comparative study.
