A Survey on Green Networks and Communications

Abstract

Green computing is the efficient use of computers and their resources, so that electronic devices can be environmentally viable and ecofriendly. It encompasses a broad range of disciplines like design, engineering, manufacturing, usage and disposal of computing devices. Green computing involves the efficient use of servers, CPU and network peripherals with resource management and proper disposal techniques to lessen e-waste generated. Adoption of Green computing assures minimal functional expenses in any organization as well as lower the detrimental environmental impacts while ascertaining maximal profits. It covers all aspects of a network architecture like PCs, switches, routers, peripherals and communication media. Green networking is the term used to refer to the process of making computer networks more environmentally friendly and energy efficient. It includes processes that will directly or indirectly reduce the energy usage and consumption thus reducing the negative
impact on the environment. Some of the best practices used in green networking are: Incorporating the concept of virtualization, High availability servers obtained by consolidation, Upgradation of equipment, managing systems in an efficient way, Using efficient techniques like video conferencing VPN’s over physical travel. Green communications can be defined as the adoption of eco-friendly, energy-efficient communication and networking advancements to truncate the usage of resources in every possible aspects of communication.
