4.1 Introduction

The Internet of Things (IoT), which can be implemented in every sphere of life, is the most promising technology of fifth‐generation (5G) and beyond 5G wireless communications. Wearable sensors, when deployed for healthcare services to sense physical data of the human body and transmit the measured data to the nearest gateway wirelessly facilitating IoT, form a network called the wireless body area network (WBAN). The concept of wireless technology integrated Internet‐based healthcare services was first coined in 2000 by Laxminareayan and Istepanian [1]. The rapid advancement in the field of wireless technologies and wearable electronics in recent times transform WBAN into a hot topic in the fields of academia and industry, to carry out top‐notch research to bring it to its full potential [2]. The main purpose of WBAN in healthcare services is the early detection of abnormalities through regular measuring of physiological data; thus, alerting the person to take necessary precautions and assisting the medical professionals to make sound ...
