IoT has many unsupported features such as geographic features location latency etc that are critical for various IoT application. To support these features fog computing is added to IoT. This review paper discusses the difference between cloud and fog and why fog is used over cloud for IoT. This paper discusses the architecture and features of fog computing for IoT applications. Security and privacy issues of fog related to various applications are also discussed., International Journal of Scientific Research in Computer Science Engineering and Information Technology, 2018, CSEIT411840
