DFDNM: A distributed fault detection and node management scheme for wireless sensor network

Abstract

This paper presents a distributed fault detection and node management scheme with the help of cellular automata in wireless sensor networks. The node failure is detected in distributed way and the cellular automata are used for network management. The linear cellular automata run on every sensor nodes and each sensor node set own state with the help of CA. The faulty are detected by neighbour node's temporal and spatial correlation of sensing information and heart beat message passing by the cluster head. The proposed distributed fault detection and node management scheme (DFDNM) can detects and manages the faulty nodes in an energy efficient manner. The simulation result shows how DFDNM perform well comparison to others faults detection algorithms. © 2011 Springer-Verlag.
