Objectives: The key constructions of Wireless Sensor Networks (WSN) are energy conservation and battery depletion of the sensor nodes which are restricted and irreplaceable. Designing an economical clustering and routing mechanism ought to incorporate these problems for large scale WSN. Methods: “Energy Aware Fault Tolerant Clustering and Routing Mechanism” is proposed in this work for efficient clustering and fault-tolerant routing. The main idea behind this mechanism is to spot a node which lies in next position to cluster head in terms of energy and configuring it to sleep mode. Findings: This is chiefly done to realize fault tolerance by activating the node in sleep mode during the failure of the cluster head. Intensive experiments were performed on this technique and the results are compared with the previous algorithms. Applications/Improvements: Energy-Aware Fault Tolerant techniques are effectively used in applications of WSN like army reconnaissance, environmental monitoring etc.
