A Novel Fault Detection and Replacement Scheme in WSN

Abstract

Abstract. Wireless Sensor Network (WSN) is a collection of nodes, which are limited in energy content and interact with each other to complete a job assigned to them. Performance of WSN may degrade because of faulty nodes present in the network. The strategy in the paper discusses about a fault detection technique, which depends upon three components of the node. The strategy exploits a node to the fullest extent possible before declaring it as faulty. Moreover the faulty-node replacement technique replaces a faulty node with a healthy node,based on a regression plain model. Optimal use of sensor node is done by reallocation of jobs of the faulty nodesto the active nodes.
