A GENERAL STUDY ON FAULT TOLERANCE IN WIRELESS SENSOR NETWORK (WSN): A SURVEY
The Wireless Sensor Networks (WSN) are deployed mostly in very large scale areas and hence the chances of occurrence of fault in the system is very high which can cause damage to the system and thus can cause system failure. Fault Tolerance is the property that lets a system continue its work even after some of the components of the system fails. Although after failure the quality of the output generated by the system might not be as good as expected but due to the fault tolerance property the process of the system will be maintained properly. This paper provides a general review on fault tolerance and some techniques used for fault tolerance in a wireless sensor network.
