Cost function for delay (CFD) in software defined network with fog computing and associated IoT application

Abstract

Fog Computing become an emerging technology and majorly adapted to IoT networks. In the IoT network Fog nodes interact directly with edge devices and create easy communication with reliable data transmission to store in cloud data centers. In this paper we proposed a Cost Function for Delay(CFD) in transmission of data from end devices to cloud data centers by passing through fog devices and other network devices in a multi hop based network. The total data transmission time included with many parameters including delay which occupies small amount of time in total data transmission time. The CFD evaluated for every local device on reach by each hop and at fog device where task offload dynamically. In our proposal we considered the greedy heuristic based approach to derive the solution effectively.
