Downlink Power Control in Two-Tier Cellular Networks With Energy-Harvesting Small Cells as Stochastic Games

Downlink Power Control in Two-Tier Cellular Networks With Energy-Harvesting Small Cells as Stochastic Games

Energy harvesting in cellular networks is an emerging technique to enhance the sustainability of power-constrained wireless devices. This paper considers the co-channel deployment of a macrocell overlaid with small cells. The small cell base stations (SBSs) harvest energy from environmental sources whereas the macrocell base station (MBS) uses conventional power …
