Design of Hierarchical Trust based Efficient Cluster Head Selection in WSN (HTECH)

Objectives: Due to restricted computational power and energy resources, aggregation of data from multiple Sensor Nodes (SNs) secure routing is a significant problem because of highly susceptible in WSNs (Wireless Sensor Networks). Hence ascertaining trustworthiness of data is vital for WSNs. Group-based Trust Management Scheme (GTMS) introduced the trust that depends on direct and indirect monitoring. However, it consumes more energy to communicate the data transmission in WSNs. The main objective of this paper is to transmit the data through the trust node and secure data transmission in WSNs. Methods: The cluster head plays an important role in the cluster-based network. In this paper, we propose Design of Hierarchical Trust based Efficient Cluster Head Selection in WSN (HTECH) which demonstrates the Cluster Head (CH) selection process based on Trust based routing in WSN. This trust is evaluated based on node cooperativeness, Unselfishness, honest and data transmission rate. Findings: The trust evaluation is used to avoid the malicious and selfish node present in the routing path. Thus, this method provides a realistic and secure approach to choose a shortest path in all trusted path. The simulation results shows that the HTECH scheme reduce both packet loss rate, delay, and improve the throughput in WSNs. Improvements: The HTECH trust routing remove the untrustworthy nodes in order to obtain a reliable passage delivery route also reduce the energy consumption when compared to the existing method.
