11.1 Introduction

Extending the cloud services near to the end-user is the basic concept of fog computing [1]. Fog computing is the emerging technology where intelligence is pulled toward the edge of the network, closer to the devices where data is being generated. According to Gartner¹ (2017), there will be 8.4 billion devices connected to the Internet at the end of 2017. Further, the network is not designed to support communication of such a large number of devices. The fog computing concepts and network parameters can play a vital role in supporting the delay sensitive applications. Thus, simulators can be used to understand the behavior of these devices and fog environments. In fog environment with respect to Internet of Thing (IoT), there are three main layers. These layers are the cloud layer, fog layer, and the device layer.

Cloud Layer – This layer is composed of a conventional cloud. A larger number of cloud data centers configured in a geographically distributed ...
