Fog computing in internet of things: Practical applications and future directions

Abstract

Internet of things (IoT) services have been accepted and accredited globally for the past couple of years and have had increasing interest from researchers. Fog architecture has been brought up in IoT for enhancing its competence in a variety of applications. Fog computing is an emerging concept that transforms centralized Cloud to distributed Fog by bringing storage and computation closer to the user end. The aim of this paper is to highlight the fundamental Fog three-tier model and emphasize its advantages, challenges and possible attacks. This paper will also focus on Fog computing models pertaining to IoT scenario that have been developed over the period to conquer the challenges of existing Fog computing architecture. This paper also highlights Fog’s real importance which will include a review of scenario-based examples. Moreover, open issues have also been discussed to be worked upon in future.
