Introduction

Wearable health monitoring devices have seen rapid growth in recent years, becoming essential tools for personal health management [1]. These devices, ranging from basic fitness trackers to advanced medical-grade sensors, offer continuous monitoring of vital health parameters, such as heart rate, blood oxygen levels, and blood pressure [2]. The primary advantage of wearables lies in their ability to provide real-time data, enabling users to track their health status and receive timely alerts for potential health concerns [3]. The design and development of wearable health devices present several challenges, particularly in terms of ensuring efficient communication systems that consume minimal power [4]. Power consumption remains a critical issue in wearables, as the need for constant data transmission demands a careful balance between energy efficiency and device performance [5].

The communication module of wearable health devices was crucial to their functionality, as it facilitates the transfer of data from the sensor to the processing unit and, in some cases, to remote servers for analysis [6]. The constant need for data transmission, especially in real-time monitoring scenarios, requires energy-efficient communication systems to extend the device's battery life [7]. Energy-efficient communication technologies play a pivotal role in ensuring that wearable health devices can operate continuously without frequent recharging [8]. Reducing power consumption while maintaining high data transfer rates was essential for improving the usability and practicality of these devices, making them more accessible for daily use by individuals [9].
