Energy-Efficient Wireless Communications with Future Networks and Diverse Devices

摘要

Telecommunication networks are responsible for approximately 2% of the global energy consumption. As data traffic continues to grow due to the proliferation of smart phone devices, reducing greenhouse emission by improving the network energy efficiency is becoming increasingly important. Such improvements may be achieved by advanced system design at both the network and the mobile terminal sides, although the majority of savings may come from the infrastructure. For instance, one promising technique for cellular network power reduction is through advanced radio resource management (RRM) to dynamically switch ON or OFF a basestation based on daily traffic variation. By switching OFF lightly loaded basestation and offloading the traffic to neighboring basestations, significant energy reduction may be possible without compromising the network performance.
