Planning and network management for energy efficiency in wireless systems

This paper presents a cellular network planning concept that contributes to the green network aspect. The presented approach consists of an energy consumption optimizing method that is based on a planning algorithm published formerly. The goal is to optimize network layout taking into account the temporal and spatial variation of traffic demands. Besides serving traffic demands and fulfilling coverage requirements, reducing power consumption is primary goal of the presented procedure. Network management is introduced by means of assuming the possibility of switching off base stations and changing layout by changing main antenna lobe directions, as well as changing transmit power level. Numerical results show these mechanisms effect on network level energy efficiency attained.
