Research Issues for Energy Efficient Cellular Networks Prof. Vijay Bhargava-2013 제5회 정보전자융합공학부 국제심포지엄 포항공과대학교 Vijay Bhargava, Harri Siitari, Ajay Agarwal, Prasant Mohapatra, Mikio Aoyama, Dongman Lee, Ben Lee


The rising energy costs and carbon footprint of operating cellular networks have led to a trend in addressing energy-efficiency amongst the network operators and regulatory bodies such as 3GPP and ITU. "Greening" the wireless networks is a vast research discipline that needs to cover all the layers of the protocol stack and various system architectures and it is important to identify the fundamental trade-offs linked with energy efficiency and the overall performance. In this talk, we identify four important aspects of a green networking where we would like to focus: defining green metrics, bringing architectural changes in base stations, network planning, and efficient system design. We begin with a brief discussion on energy efficiency metrics. Since Base Stations (BSs) consume a major chunk of input energy, we discuss the energy efficiency of BSs. Next we discuss energy efficiency from a network planning perspective, based on smaller cells for heterogeneous networks. For system design, we put a special emphasis on cognitive and cooperative techniques in order to realize energy efficient cellular systems. Finally we discuss some broader perspectives and possible future trends in realizing a green cellular network technology.
