The evolution to a virtualised network framework had benefited the network operators by reducing the capital expenditure, streamlining the operational processes, reducing the time to deploy new functionalities and rapidly scale up the network capacity. The telecom researchers thus proposed to lug the cloud from the sky to the ground to mitigate some of these concerns. The cloud morphed into the fog, thus the name 'fog networks'. The Fog network concept was coined by Cisco and is well within the scope of the 5G network paradigm. With the advancement of semiconductor technologies, the edge devices are becoming more intelligent. The Power Smart Grid is not a new concept. It aims to pilot the control information flow between the power plants more efficiently, optimizes power distributions, diagonizes and isolates circuit failures, scale up, scale down power level dynamically, actuate smart power distribution etc.
