Fault Management Using Cluster-Based Protocol in Wireless Sensor Networks

Abstract

Abstract-Fault tolerance has been identified as key challenges in the design and operations of Wireless Sensor Network (WSNs). Failures are inevitable in wireless sensor networks due to inhospitable environment and unattended deployment. Therefore, it is necessary to detect the networks for recovery from the failure to sustain it. WSNs are self-organized using clustering algorithms to conserve energy. LEACH (Low Energy Adaptive Clustering Hierarchy) protocol is one of the significant protocols for routing in WSN. In LEACH, sensor nodes are organized in several small clusters where there are cluster heads in each cluster. These CHs gather data from their local clusters aggregate them & send them to the base station. The proposed scheme is supposed to be an efficient fault detection and recovery mechanism to make the network fault-tolerant and achieve reliability and quality of service. Performance analysis and evaluation will be made using several scenarios of wireless sensor networks.
