Abstract

In today’s healthcare environment, the Internet of Things technology provides suitability among physicians and patients, as it is valuable in numerous medicinal fields. Wireless body sensor network technologies are essential technologies in the growth of Internet of Things healthcare paradigm, where every patient is monitored utilising small-powered and lightweight sensor nodes. A dual-hop, inter–wireless body sensor network cooperation and an incremental inter–wireless body sensor network cooperation with energy harvesting in the Internet of Things health-based paradigm have been investigated and designed in this work. The three protocols have been named and abbreviated as follows: energy harvesting–based dual-hop cooperation, energy harvesting–based inter–wireless body sensor network cooperation and energy harvesting–based incremental inter–wireless body sensor network cooperation. Outage probabilities for the three designed protocols were investigated and inspected, and mathematical expressions of the outage probabilities were derived. The simulation and numerical results showed that the energy harvesting–based incremental inter–wireless body sensor network cooperation provided superior performance over the energy harvesting–based inter–wireless body sensor network cooperation and energy harvesting–based dual-hop cooperation by 1.38 times and 5.72 times, respectively; while energy harvesting–based inter–wireless body sensor network cooperation achieved better performance over energy harvesting–based dual-hop cooperation by 1.87 times.

Highlights

At present, Internet of Things (IoT) is one of the most powerful communication standards of the 21st century
There have been several works on the security of IoT health-based paradigm, for example, a secure IoT healthcare-based paradigm that operates over the Wireless body sensor network (WBSN) was introduced by Yeh.[13]
We reveal that the proposed energy harvesting (EH)-IIWC protocol achieves better performance in terms of outage probability over energy harvesting–based inter-WBSN cooperation (EH-IWC) and EH-DH in an IoT health-based paradigm

Summary

Introduction

Internet of Things (IoT) is one of the most powerful communication standards of the 21st century. Every sensor in the WBSN can gather physiological signals such as electrocardiogram (ECG), electroencephalogram (EEG) and forward these signals to the coordinator node (CN) over a wireless medium or human body channel (HBC) for further analysis and inspection.[6] WBSN paradigms are capable of giving long-range healthcare monitoring without constraining a person’s mobility or activity. These paradigms are used to create intelligent and inexpensive healthcare monitoring to be used for the diagnostic procedure.[7] the performance of WBSN systems is profoundly affected by the limited energy of sensors and coordinators. One of the most suitable techniques for a WBSN system to harvest energy is radio frequency–based energy harvesting (RF-EH).[8,9] For RF-EH, the received radio signals are transformed into DC power, stored in the battery.[10]
