Enhanced Routing Scheme Using Dynamic Clustering For Energy Reduction in WSN

Wireless sensor networks (WSNs) have gained enormous attention for their wide range of applications such as environmental monitoring, military surveillance, health care, disaster management. Energy is the main constraint of wireless sensor network due to irreplaceable and limited power source of the sensor nodes. Clustering is the most popular topology control method to reduce energy consumption and improves scalability of WSN. Here we proposed a distributed fault tolerant clustering algorithm called DFCA which uses a cost function of the cluster heads for the formation of cluster. We also present a distributed run time recovery of the sensor nodes from the faulty cluster due to sudden failure of the cluster head. The experimental results show the strength of the proposed algorithm. We can remove this fault by using back up cluster or we can set the root information as a prefix.
