Energy Saving and Edge Computing
▶ Introduction

Next-generation wireless networks are expected to significantly rely on edge applications and functions that include edge computing and edge artificial intelligence (edge AI). To successfully support such edge services within a wireless network with mobile edge computing (MEC) capabilities, energy management (i.e., demand and supply) is one of the most critical design challenges. It is imperative to equip next-generation wireless networks with alternative energy sources, such as renewable energy, in order to provide extremely reliable energy dispatch with less energy consumption cost

The stringent requirements of MEC applications and functions fathom the high capacity and dense deployment of MEC hosts to the upcoming wireless networks. However, operating such high capacity MEC hosts can significantly increase energy consumption. Thus, a base station (BS) unit can act as a self-powered BS. To provide sustainable edge computing for next-generation wireless systems, each base station (BS) with MEC capabilities unit can be equipped with renewable energy sources. Thus, the energy source of such a BS unit not only relies solely on the power grid, but also on the equipped renewable energy sources. In particular, in a self-powered network, wireless BSs with MEC capabilities is equipped with its own renewable energy sources that can generate renewable energy, consume, store, and share energy with other BS units.

The MEC is already included as an essential component in the smart infrastructures, such as the smart city, smart factory. Meanwhile, a microgrid is also considered to be prominent in those MEC infrastructures. As a result, microgrid can be useful energy supplement to MEC, while the necessity of the renewable energy powered base stations (BSs) operation is established more than a decade ago by the Ericsson (telecommunications company). MEC confronts with the sustainability issue to manage the computation with respect to energy consumption and the competence of MEC operation is depending on efficient energy supply for microgrid empowered MEC networks. However, the MEC receives tasks with the uncertainty, where the characteristic of the energy consumption relies on the computational payload size. Furthermore, the reliability and stability of the microgrid energy supply contingent on energy generation of the renewable (e.g., solar, wind, biofuels, etc.) and nonrenewable (e.g., diesel generator, coal power, and so on) energy sources.

Next-generation wireless networks with edge computing capabilities enabled high computational heterogonous MEC hosts with self-powered functionalities. To save the energy consumption of the MEC network, it is imperative to efficiently manage the energy generation and consumption for the network. Further, the high computational MEC tasks that include AI services and applications are needed to manage in such a way so that the quality of service (QoS), as well as quality of experience (QoE), are being fulfilled.
