Medical and healthcare is one of the most favorable application areas of IoT. There are many prospective use cases of medical application of IoT, for example, remote health monitoring, fitness programs, chronic diseases and care for elderly persons. Compliance with treatment and medication in home and healthcare organization is also an important application case. Thus, various medical devices, sensors, diagnostic and imaging devices can be thought of as smart devices/objects constituting a part of IoT. IoT-based healthcare is expected to offer low cost care, better quality of life, and enriched user experience. Even, from a healthcare organizational point of view, IoT is potential enough to reduce device downtime through remote provision. Also, it rightly identifies the optimum time of replenishing supplies for various devices to continue their operation smoothly. Moreover, it offers efficient scheduling of limited resources by ensuring best utilization of them and hence serves more patients.
Over the past few years, this field has attracted huge attention of researchers to meet the potential of IoT in healthcare by addressing a multitude of practical challenges. As a consequence, there are already numerous applications, services, and prototypes on this field. Research trends in IoT-based healthcare include diverse topics, for example, network architectures and platforms, new services and applications, interoperability and security. There are also important research activities in developing policies and guidelines for deploying IoT technology in medical field in many countries and organizations around the world. However, IoT in healthcare is still in its infancy. At this stage, a thorough knowledge on the current research status of IoT in healthcare is incredibly useful to various stakeholders to do more research in this area. Recently, we have done a comprehensive survey where we appraise the state of the art of IoT-based healthcare research trends and uncover various issues that need to be addressed to transform healthcare technology through IoT innovation. Our survey has been accepted by IEEE Access Journal. Please follow this link to read the whole article.
