Abstract :
Reducing energy consumption in wireless communications has attracted increasing attention recently, as power costs have become a significant component in mobile network operators OPEX. In this work, we consider a heterogeneous mobile networks topology with coexisting macrocellular and microcellular Base Stations (BSs) and propose two algorithms to optimally determine the operational mode of BSs under various traffic load conditions and achieve overall energy consumption minimization for efficient mobile network operation. Different traffic loads are investigated via simulation campaigns and our proposed optimization schemes yield quite satisfactory energy saving gains compared to Full Operational Topology (FOT) networks in all scenarios of interest examined.
