Fog computing architecture, benefits, security, and privacy, for the internet of thing applications: an overview

To overcome the problem related to cloud computing such as high latency and to increase the efficiency of data processing, Fog computing was proposed and implemented close to IoT devices. This structure helps these devices to meet the requirements of location awareness and low latency, which can not be met by cloud computing. Many benefits, applications, and security and privacy issues were discussed in the literature for Fog computing. This paper provides an overview of all these aspects to provide the reader with a holistic understanding of Fog computing. More focus is given to the security and privacy issues in our discussion since these issues may hinder organizations from implementing Fog computing. The findings of this paper show that a few studies that discussed empirical findings of using Fog computing and many questions related to security and privacy issues are ye to be answered in future research.
