Fog computing with the integration of Internet of things: Architecture, Applications and Future Directions

Information Technology industry has competitiveness on the basis of technological environment. In this environment, the use of cloud services has been increasing to provide high quality services and fast delivery of products to cloud users. But still some issues are unresolved especially, related to latency between cloud data center and end user. Fog computing is used to support increasing demand of IT service with the collaboration of cloud computing. It provides computational and storage services of cloud proximate to IoT devices. Fog computing is enhancement of the cloud-based network and computing services. This paper discusses the concept, architecture of fog computing and implemented application. It also highlights about resource provisioning techniques to identify over utilization of fog nodes. Along with the resource utilization, different scheduling terminologies have also been discussed on various parameters. The motive of this survey is to understand the application of fog computing to improve the existing smart healthcare system.
