Research on green radio networks

Abstract

Energy consumption in wireless networks, especially in wireless cellular networks, is relevant to the escalation of operating energy consumption, which causes adverse impact upon the environment. With the worldwide growth of data service in wireless cellular networks and the increase of energy cost, researchers pay more attention to green radio that takes reducing energy consumption into account. Adding relay stations between the base station and the mobile stations in a cellular system can save energy by extending network coverage, overcoming multi-path fading and increasing the capacity of the system.
