A Systematic Review on the Internet of Medical Things: Techniques, Open Issues, and Future Directions

IoT usage in healthcare is one of the fastest growing domains all over the world which applies to every age group. Internet of Medical Things (IoMT) bridges the gap between the medical and IoT field where medical devices communicate with each other through a wireless communication network. Advancement in IoMT makes human lives easy and better. This paper provides a comprehensive detailed literature survey to investigate different IoMT-driven applications, methodologies, and techniques to ensure the sustainability of IoMT-driven systems. The limitations of existing IoMT frameworks are also analyzed concerning their applicability in real-time driven systems or applications. In addition to this, various issues (gaps), challenges, and needs in the context of such systems are highlighted. The purpose of this paper is to interpret a rigorous review concept related to IoMT and present significant contributions in the field across the research fraternity. Lastly, this paper discusses the opportunities and prospects of IoMT and discusses various open research problems.
