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. Keywords Fog Edge computing IoT Cloud Privacy Security Smart city Big data

1 Introduction Internet of Things (IoT) has matured over with the passage of time. Now we can see IoT applications in many areas of computing and technology. In particular, IoT plays a critical role in the making of smart cities, which are now implemented on a large scale in the developed economies on the planet earth. A snapshot of IoT application is shown in Fig. 1. Basically, IoT is an information technology infrastructure which consists of sensors, actuators and advanced services for interconnecting physical and virtual world with the help of sophisticated communication technologies [1, 2]. Ubiquitous aspects of IoT have been studied with various perspectives in [3, 4]. Most of the IoT based devices such as Smart-phones, Smart-watches, health monitoring, and drug delivery wireless devices are of limited power, storage, and computing capabilities. Therefore they rely heavily on the cloud data centers to collect huge amounts of sensed data and for analyzing it, in addition, to providing many of services and features to end user like accessibility, scalability, mobility, providing resources for storage and computation functions with low cost, etc. [5, 6]. With the ongoing research and innovations. Various weaknesses of the clouds data center have been exploited by various articles including [7, 8]. This research shows that the clouds based computing and data centers will not satisfy the increasing requirements of smart objects whose number is expected to exceed 50 billion by 2020. This explosion in the IoT objects
