Impact of IoT in Healthcare: Improvements and Challenges

Since last one decade, IoT has been a challenging field of application for the simulation in real-time environment. Rapid changes in information and communication technologies have assisted to the wider usage of Internet of Things (IoT) in areas such as intelligent transport systems, intelligent cities, intelligent healthcare, intelligent homes, intelligent grid, industry automation, smart farming and many others. Among them healthcare has always been a hot interest among various research communities and is a rapidly growing area with the advancement of technology. Managing health issues is becoming a serious factor in healthcare system, as insufficient healthcare services are available to meet the increasing demands of ageing population with chronic diseases. So, the world healthcare system needs the transformation from clinic-centric environment to personalized information allied environment. In modern healthcare system, physicians and patients can be brought together with the usage of IoT technologies for automated and efficient monitoring of daily activities of all age group people and to provide ‘one-stop’ service to people at remote locations by network architecture that provides continuous monitoring of body signals based on sensors. As rapid development occurred in controlling healthcare, this research aims in describing the history, development of futuristic studies and standard assessment of emerging technologies of IoT in healthcare system. Further, various factors affecting the health concerns are disseminated through the latest findings of IoT which will serve as basis of information for scientist, technocrats, researchers and common people in and beyond to this area. This research work also provides an approach to future trends, advancement in the technology made so far and to cope with the challenges such as management of data, compatibility, security, adaptable and privacy.
