A Survey: Faults, Fault-tolerance & Fault Detection Techniques in WSN

Present modern world become more automated, forecast-able and accurate by using wireless sensor network. To make a WSN more undependable and reliable, researchers have to make advance research on each and every domain of WSN, mainly on fault tolerant techniques. This paper thoroughly investigate the mechanism to achieve a fault tolerant network. The prime focus of this paper is to make understanding about faults, failures and its classification and detection in the network and explain the techniques to detection of fault, prevention of fault and recovery of the fault in the sensor network, these are the very crucial parameters of a fault tolerant network.
