Survey on Fog Computing: Architecture, Applications, Taxonomy and Its Role on the Internet of Things

Because of the dramatic increase in IoT devices usage, the traditional computing needs are changing growingly. Various types and huge numbers of devices like sensors and actuators are interconnected with clouds of servers on IoT. There are many applications of cloud computing in the context of IoT devices. Here, a large volume of data including multimedia data like image created by sensors is transmitted to servers in clouds through networks. However, the cloud alone cannot provide the required real-time responses with location aware services. To support the computational demand of real-time latency-sensitive applications a new computing paradigm named “Fog computing” has been introduced. Fog computing resides closer to the end devices and extends the cloud-based computing, storage and networking facilities. In this Paper, we discuss the evolution of distributed computing from the cloud computing to the fog computing, fog computing architecture, the current status on fog computing research along with a taxonomy of various existing works in this direction.
