A Deep Investigation of Architectural Elements and Computing Technologies for Internet of Medical Things

The exponential growth of the world's population along with the scarcity of medical personnel pose several challenges towards medical requirements in many peripheral areas to decrease the mortality rate and lessen the severity of chronic diseases. IoMT a category of IoT promotes significant inroads in the field of telemedicine to offer health services at reduced healthcare costs, improved quality of service and utilization of resources in an efficient manner. In IoMT, emerging technologies like wearable technology, block chain technology, machine-based intelligence, and sensor miniaturization have the capability to excel in digital healthcare. IoMT deployed with intelligence techniques paves the way to shift the focus from single prescriptive to preventive, predictive, diagnostic and monitoring measures to get diagnosed in a short span of time. Real-time IoMT applications confront significant problems in terms of latency, standardization, size, and power usage. The objectives of the suggested architecture were to comprehend state-of-the-art IoMT technology and to tackle key issues. In this paper, Section 1 focuses on explaining the significance and benefits of IoMT in the field of health care. Section 2 presents the multi-layer architecture and functions of each layer. Furthermore, Section 3 highlights the classification of IoMT devices within the medical environment. Additionally, section 4 provides insights on enabling technologies that have been deployed with IoMT to provide sustainable solutions across the globe. Section 5 elaborates on some of the remarkable challenges faced by IoMT devices in the current scenario.
