IOT ENABLED CLOUD BASED HEALTHCARE SYSTEM USING FOG COMPUTING: A CASE STUDY
Journal of Critical Reviews · 2020
Fog computing or fog network is designed to support distributed and decentralized computing platform by reducing the burden on cloud computing. Using IoT infrastructure many devices are connected to the fog network to send and receive data. The three layers of fog network are used to sense the data from the IoT devices, to process the data and finally to present the data in the application layer. There are many applications of fog computing such as e-commerce, mobile services, mobile networks, agriculture, smart buildings, self-driven auto mobiles, smart grids and cities, healthcare and image processing etc. This paper gives overview of the fog architecture, hierarchy of different layers, applications, challenges and research directions. A better IoT enabled cloud based healthcare system using fog computing model is discussed in this paper to assist patients in an efficient manner.
