Neighbor Co-ordination based Fault Node Detection Algorithm for Distributed Wireless Sensor Networks

Abstract

Abstract-In this paper a neighbor coordination approach based fault node detection technique for distributed wireless sensor networks (WSNs) is presented. Because of large deviation in incorrect data transmitted by various faulty sensor nodes(SNs), the statistical based approach of fault detection using mean, mode, median and other hypothetical test based schemes becomes inappropriate for large scale distributed WSNs. This research concentrates on fault node identification in distributed WSNs where the neighboring nodes attempt to identify the faulty SN through comparing their sensed data with all of their neighbor's data. The main aim of this study is to design a less complex fault node detection algorithm, which can easily detect faulty sensor nodes present in distributed WSNs by using a neighbor coordination approach based fault node detection technique. The simulation results show the proposed algorithm is effective in terms of performance measures like detection accuracy, false alarm rate and false positive rate which are far better in than conventional methods used to detect the faulty SNs in WSNs.
