He is a past President of IEEE Information Theory, and is currently serving as the President of the IEEE Communications Society.

Outline of talk

The rising energy costs and carbon footprint of operating cellular networks have led network operators and regulatory bodies, such as 3GPP and ITU, to show a trend in addressing energy efficiency. "Greening" wireless networks is a vast research discipline that needs to cover all layers of the protocol stack and system architectures, and it is important to identify the fundamental trade-offs between energy efficiency and overall performance. In this paper, we direct our focus to four important aspects of green networking: defining green metrics, bringing architectural changes to 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 our system design section, we put a special emphasis on cognitive and cooperative techniques in order to examine energy efficient cellular systems. Finally we discuss a few broader perspectives, and possible future trends, in realizing a green cellular network technology.
