Abstract: Abstract Traditionally the aim of telecommunication mainly focuses on achieving easy implementation with large capacity. Environmental degradation emphasis to focus on energy efficient design with aim to achieve green networks [1]. Telecommunication along with its advancements also addressing the significant environment impact, created by themselves as well as cost on power usage. The overall goal of next generation of wireless to provide ubiquitous and unlimited connectivity to a massive number of Internet of Things (IoT) and machine-type devices/users having diversity in quality of service, supporting substantial and heterogeneous traffic demands with great reduction in energy consumption using energy-efficient communication protocols, transceivers and computing technologies[3][4]. In India cellular technology the evolution of 5G proves to fulfil the user demands in present and upcoming years. This will increase the energy consumption by which will result in excess emission of co2. We are discussing some techniques include device-to-device communication (D2D), massive Multiple-Input Multiple-Output (MIMO) systems, heterogeneous networks (HetNets) and Green Internet of Things (IoT) as a part of future cellular system. In this paper, the different techniques for the green communication technology along with the challenges in it are discussed [2].
