FAULT DETECTION IN WIRELESS SENSOR NETWORKS

Abstract

Wireless Sensor Networks are infrastructures containing sensing, computing and communication elements that aim to give its controllers the ability to measure, collect and react to occurrences in the monitored environment.WSN focus on interaction with environment. Nothing is perfect in this universe. WSN may also be failure prone. In order to maintain the network quality of service, it is mandatory for WSN to be able to detect the faults and take appropriate actions to handle them. The main aim of this article is to give an introduction with faults in WSN, and their detection approaches. Also it provide a place where one can have interaction with some efficient fault detection algorithms such as DFD scheme, localized fault detection algorithm and CDFD algorithm etc.
