FEHCA: A Fault-Tolerant Energy-Efficient Hierarchical Clustering Algorithm for Wireless Sensor Networks

Technological advancements have led to increased confidence in the design of large-scale wireless networks that comprise small energy constraint devices. Despite boost technological advancements, dissipation and fault tolerance are amongst key deciding factors while designing deploying sensor networks. This paper proposes a Fault-tolerant Energy-efficient Hierarchical Clustering Algorithm (FEHCA) for (WSNs), which demonstrates energy-efficient clustering fault-tolerant operation cluster heads (CHs). It treats CHs as no special node but equally prone faults normal sensing nodes cluster. The proposed scheme addresses some limitations prominent hierarchical algorithms, such randomized election after each round, results significant dissipation; non-consideration residual selecting heads, etc. utilizes capability vector quantization partition deployed sensors into an optimal number clusters ensures almost entire area be monitored is alive most network’s lifetime. supports better decision-making compared decisions made on basis limited data few rounds communication. implemented both friendly well hostile deployments. simulation encouraging validate algorithm.
