Abstract
The idea of Fog computing or Edge Computing is to extend the cloud nearer to the Internet of Things (IOT) devices. Through the internet of things (IOT), we can generate a numerous volume and variety of data. With the increase in the number of internet connected devices, the increased demand of real-time, low latency services, data security are the biggest challenges for the cloud computing framework. In order to overcome above challenges, Fog Computing came into picture. The computing reduces the predictable latency in the latency-sensitive of IoT applications such as healthcare services which is primary objective of this computing. The paper argues that the Fog Computing is the best platform solutions towards this goal for a number of critical IoT services and applications, namely, Connected Vehicle, Smart Grid, Smart Cities, and, in general, Wireless Sensors and Actuator Networks (WSANs).
