Mobile applications and social networks tend to enhance the needs for
high-quality content access. To address the expeditious growing demand for data
services in 5G cellular networks, it is important to develop distribution techniques
and an efficient content caching, aiming to significantly reduce redundant
data transmission and, thus, improve the efficiency of the networks. In
modern communication systems, caching has emerged as a vital tool for reducing
peak data rates. It is anticipated that energy harvesting and self-powered
small base stations are the fundamental part of next-generation cellular networks.
However, uncertainties in energy are the main reason to adopt energy
efficient power control schemes to reduce SBS energy consumption and ensure
the quality of services for users. Using the edge cooperative caching such as
energy efficient design can also be achievable, which reduces the usage of the
capacity limited SBSs backhaul and the energy consumption. To support the
huge power demand of cellular network, renewable energy harvesting technologies
can be leveraged. In addition to this, power supply to the infrastructures is
themain challenge to the mobile network operators (MNOs) especially in terms
of economic optimum, sustainability, and green energy in developing countries
for the growth of cellular networks. Renewable energy–based solutions for
MNOs not only reduce the overall carbon dioxide emissions but also provide
numerous profits.
