The concept of energy-efficient networking has begun to spread in the past few years,
gaining increasing popularity. Besides the widespread sensitivity to ecological issues, such …

OFDMA has been selected as the multiple access scheme for state-of-the-art wireless
communication systems. Efficient resource allocation in OFDMA wireless networks is …

In this paper, we investigate dynamic base station (BS) switching to reduce energy
consumption in wireless cellular networks. Specifically, we formulate a general energy …

Cell size in cellular networks is in general fixed based on the estimated traffic load.
However, the traffic load can have significant spatial and temporal fluctuations, which bring …

Energy-efficiency, one of the major design goals in wireless cellular networks, has received
much attention lately, due to increased awareness of environmental and economic issues …

In this paper we study with simple analytical models the energy-aware management of
cellular access networks, trying to characterize the amount of energy that can be saved by …

Recently, there is great interest in considering the energy efficiency aspect of cellular
