Green Network Solutions

Abstract

This chapter presents state‐of‐the‐art green communication solutions and analytical models for both network operators and mobile users at different traffic load conditions. In particular, green wireless networks can be distinguished for the proposed solutions and models to enhance and analyse the energy efficiency based on the call traffic load condition. At a low and/or bursty call traffic load, resource on‐off switching techniques are adopted, while scheduling techniques are employed at a high and/or continuous call traffic load. Radio resource‐scheduling techniques have been proposed for a high call traffic load condition. The chapter reviews green solutions at different traffic load conditions, and presents a description of the existing green projects and standards. It also presents future research directions to address the limitations of the existing approaches. The chapter suggests that, as future research, green solutions should capture the trade‐off in energy efficiency among network operators and mobile users, and should be designed to balance a trade‐off.
