Fog Computing: Characteristics, Challenges and Issues

In the present era, Fog computing is one of the most important technologies used by many companies and users. This technology has many qualities, characteristics, advantages and offers many services to end-users like compute, and application services. Besides, it appropriates for wireless sensor networks (WSNs), Internet of Thing (IoT) and supports heterogeneity appliances, such as Fog appliances, switches, edge routers, and access points. In this research paper, we survey Fog technology in terms of the layers and the primary features. Also, this paper is constructed by illustrating the importance of the challenges and issues of Fog computing included “privacy and security issues” that facing this technology. Finally, we present the benefits of merging between the Fog computing and other techniques like IoT and Cloud. This paper will contribute to providing the researchers who want to study the Fog computing in terms of aspects that previously mentioned.
