Advantages of using fog in IoT applications

Abstract

Edge computing (EC) has emerged as an attractive and interesting topic for research. It is an extension of cloud computing, used for non-centralized computing with various new features and solutions. In particular, edge computing deals with Internet of Things (IoT) based applications and services. Fog, which sometimes is also referred as edge, is basically a type of EC model, and its features can support a wide range of applications and services of IoT. In this article, we shall explore importance of Fog in IoT applications. In this paper, we shall provide a comprehensive comparison between Fog and cloud. In the process, we shall also provide practical examples to explain the importance of exploiting each of the properties or attributes of Fog which play critical role in facilitating new applications. In addition, we have proposed some novel applications of Fog for protecting the privacy in IOT based applications. Show more
