Fog-centric IoT Smart Healthcare: Architecture, Applications, and Case Study

The history of human civilization has shown that the major strength behind the advancement of technology has always been the hu- man’s need for medical and healthcare applications. For decades, cloud computing has dominated healthcare information systems based on everything as a service model. However, the long service delay offered by cloud applications is one of the significant limitations. During emergency situations, monitoring of patient’s health, decisions must be made quickly with limited available resources, as it directly affects the patients’ lives. The introduction of edge computing and fog computing as optimal technologies has solved these latency-related problems. This paper provides an open architectural framework for fog-based Internet of Healthcare (Fog-IoH) applications. Besides, various services and applications support in the integration of fog with the IoT health sector have been indicated. Further, the applicability of IoT in healthcare has been discussed by presenting a case study of smart gloves wearable devices.
