Abstract
Future smart healthcare systems—often referred to as Internet of Medical Things (IoMT) – will combine a plethora of wireless devices and applications that use wireless communication technologies to enable the exchange of healthcare data. Smart healthcare requires sufficient bandwidth, reliable and secure communication links, energy-efficient operations, and Quality of Service (QoS) support. The integration of Internet of Things (IoT) solutions into healthcare systems can significantly increase intelligence, flexibility, and interoperability. This work provides an extensive survey on emerging IoT communication standards and technologies suitable for smart healthcare applications. A particular emphasis has been given to low-power wireless technologies as a key enabler for energy-efficient IoT-based healthcare systems. Major challenges in privacy and security are also discussed. A particular attention is devoted to crowdsourcing/crowdsensing, envisaged as tools for the rapid collection of massive quantities of medical data. Finally, open research challenges and future perspectives of IoMT are presented.
Highlights
Improved living conditions and availability of quality healthcare have increased the life expectancy and aging population share in most of the countries
We present and discuss the main aspects and challenges in providing the communication framework for Internet of Things (IoT) smart healthcare
It is crucial that the costs must be kept as low as possible to ensure mass deployment. This means that simple architectures and simple protocols are employed while maintaining the levels of reliability required by a healthcare type of system. Another important aspect to ensure the successful operation of such a technology is the network infrastructure that needs to be deployed at a national and international level to provide a seamless operation to users/patients with chronic health issues
Summary
Improved living conditions and availability of quality healthcare have increased the life expectancy and aging population share in most of the countries. Smart healthcare is a promising WSN IoT application area, that will undoubtedly bring significant benefits to citizens Such applications will remotely deliver healthcare services, bringing significant cost savings as well as allowing patients to live independently in their own homes or in a family environment for longer periods of time. These systems will enable early detection and preemption of diseases and significant improvement of patients’ quality of life. In this paper we have discussed and analyzed various low-power IoT communication technologies suitable for smart healthcare applications. A conclusion highlights key findings of this survey by indicating open issues and future trends in the emerging field of smart healthcare
