An energy-efficient and secure framework for IoMT: An application of smart cities

Abstract

The Internet of Medical Things (IoMT) has played an unrivaled role in rendering the ever-growing advancements in remote healthcare and sensor informatics. The body-sensor devices employed in remote healthcare applications are not only resource-constrained but are also vulnerable to various security attacks. Hence, to pact with the energy limitations and security vulnerability of these body-sensor devices, in this paper, we suggest ESRO: An Energy-efficient and Secured Communication framework using recently proposed meta-heuristic approach, i.e., Remora Optimization Algorithm (ROA). We employ a distributed cluster-based routing mechanism with the novel secured selection of Cluster Head (CH) using ROA. We ensure secured transmission using risky mode and risky mode. Extensive simulation of the ESRO demonstrates the supremacy of the proposed work over the existing techniques when evaluated on a benchmark of different performance metrics. ESRO not only preserves the energy but also ensures secured communication for IoMT.The Internet of Medical Things (IoMT) has played an unrivaled role in rendering the ever-growing advancements in remote healthcare and sensor informatics.
