Lifetime improvement of wireless sensor networks by employing Trust Index Optimized Cluster Head Routing (TIOCHR)

Abstract

Since the low cost and widespread accessibility of the sensors, Wireless Sensor Networks (WSN) turned out to be the most significant research field. The WSN is used in a number of different applications and the primary goal is accomplished with efficient communication between the sensors. On the other hand, due to the limited energy backup, effective communication in sensors is notoriously difficult to perform. Although numerous routing solutions have been developed for WSN, the extant literature only contains a limited number of trust-based options. This article describes a trust-based optimized clustered routing method that is energy efficient and is supported by Trust Index Optimized Cluster Head Routing (TIOCHR) algorithm. The selection of Cluster Head (CH) is influenced by energy backup, packet delivery rate and the packet consistency, which are considered as significant trust metrics. In order to assure both reliability and integrity, the most trustworthy way out of all of the potential paths is chosen. The experimental analysis of the proposed algorithm is satisfactory with regard to energy efficiency and network lifetime.
