Fog-Based Smart Healthcare Architecture in IoT Environment

The variety of services offered by IoT in different applications such as smart homes, smart mobility, smart wearables, and smart cities have made our lives easier. This transition from centralized approach to fully distributed environment proves applicability of IoT in healthcare sector. However, management of healthcare for ever increasing aging population with several diseases is a challenge due to insufficient availability of healthcare services and resources. The possible solutions could be shifting from hospital-centric treatment to home-centric treatment while connecting individual entities such as patients, hospitals, and services with each other for remote patient monitoring. This real time monitoring requires computation at fog layer to support minimal latency. This paper provides architecture of fog driven IoT e-healthcare along with its various services and applications. In addition, the challenges and solutions related to IoT healthcare in terms of data storage, scalability, and security concerns have been addressed.
