Extending Network Lifetime in Wireless Body Area Nanonetworks: A Design of a Cluster-Based Routing Protocol

Abstract

A Wireless Nanosensor Networks (WNSNs) consists basically of a group of nanonodes that communicate with each other through a wireless transmission in an adhoc manner. The recent developments in nanotechnology and wireless communication, to be used in various applications, foster the development of Wireless Body Area Nanonetworks (WBANNs). They are gaining traction as crucial networks for reducing the demand for patients and assisting the elderly and chronically sick in living independently. One of the fundamental issues in wireless nanosensor networks (WNSN) is to fulfill the nanonodes' energy constraints while maintaining system reliability. Clustering technique has been demonstrated to be a well-organized approach to provide energy-efficient communication for WNSNs. A cluster-based routing system for wireless body area nanonetworks is presented in this study, which allows data to be transferred through the network with minimal energy consumption and a longer network lifespan through multi-hop communication. When compared with the benchmarked protocol, simulation results demonstrate that the proposed protocols extend network lifetime and reduce energy usage with an average performance improvement of 28.49% in terms of network lifetime.
