Abstract
The Internet of Things (IoT) is a network of wirelessly linked interconnected digital devices that can capture, transmit and store data without involving human or machine intervention. IoT offers several of the benefits for modernizing and improving healthcare delivery, including the ability to anticipate health conditions ahead of time and diagnose, treat and track patients both in and out of the hospital. Government leaders and decision makers around the world are putting policies in place to provide health care services using technology, particularly in light of the new COVID-19 pandemic. The observation of this paper is to provide a comprehensive insight into how IoT be used successfully in healthcare by discussing USE CASE applications along with location and enabling technologies that could reshape IoT-based health care solutions. In addition, providing a comprehensive survey on the benefits of IoT-based health care and extensive knowledge on the issues that must be tackled to stabilize the IoT-based healthcare environment, IoT-based smart devices and systems, and a variety of IoT applications in the healthcare industry. Finally, the obstacles and opportunities of IoT-based healthcare growth are discussed.
