Abstract
Reducing power consumption in wireless communication networks has been the concern of many researchers over the last decade. In this paper we study the performance of two recently proposed methods for increasing the energy efficiency of green cellular systems, namely base station (BSs) cooperation and cell zooming techniques. We investigate the trade-off between the area spectral efficiency (ASE) and energy efficiency (EE) of these two models and compare this with the basic cellular system, which is used as a reference. We derive novel mathematical expressions for the ergodic capacity in these three systems, which are then are used to compute the ASE and EE of the different scenarios.
