Trust based energy efficient clustering protocol in wireless sensor networks for military applications

Abstract

Wireless sensor network finds its prominence in military applications because the sensing nature of sensors deduces uncertainty. As the sensors may work in harsh environments, minimal or no manual attention can be given to the sensors. Hence they are prone to adversary attacks. With the objective of obtaining security in these environments, trust based energy efficient method TBEM is suggested for clustered wireless sensor networks. By energy efficient and trust based clustering, security and decrease in energy deprivation in Wireless sensor networks can be achieved. The method is compared with existing Low Energy Adaptive Clustering Hierarchy LEACH protocol. The achieved minimal false positives and false negatives are presented for performance analysis.
