Fault detection in wireless sensor networks

Mishra, S (2014) Fault detection in wireless sensor networks. BTech thesis.



Wireless sensor networks having a growing demand needs them to be functionally error-free and efficient in delivering data. A WSN consists of a group of spatially distributed sensors which are deployed in environment to monitor temperature, sound and pressure. They are also used for military, medical and traffic monitoring purposes. Hence, here we propose a distributed algorithm in that helps finding out the erroneous nodes and removing them from the network so as to prevent faulty data from entering the network. This algorithm is implemented in stages, i.e. first the node readings are compared to its previous values to check consistency of data and then it is disseminate to its neighboring nodes to check their error status and subsequently remove them from the network.
