Shortest Green Optimal Paths Computation in Fog Cyber Physical Systems

The use of cloud computing to meet the needs of the Internet of Things (IoT) has created a cloud computing technology. Today, fog-computing environments are a good platform for cyber physical system networks. However, fog calculations also suffer from significant challenges. One of these challenges is achieving energy efficiency and meeting green energy standards. The realization of the green energy framework in this technology ensures that this new technology is environmentally friendly and makes data transfers feasible with less energy consumption and less carbon dioxide emissions. Therefore, in this article, while studying the existing methods, by presenting a new optimal architecture and applying it to the existing methods; we will present a new method to reduce energy consumption in fog networks. The new method, which is based on proper linear programming, is called Optimal Power-Rate Routing Solution (OPRRS) and minimizes energy consumption in data transmission path and processing units. Computer examples show that the new method reduces energy consumption in cyber physical systems compared to previous methods.
