Energy Harvesting and Cell Zooming in Heterogeneous Random Cellular Networks
Atieh R. Khamesi, Visiting Ph.D. student, Wireless@VT investigates network efficiency and green communications in heterogeneous cellular networks (HetNets) as a promising network structure for the 5G using stochastic geometry.
Abstract: We introduce two Cell Zooming (CZ) techniques applying to HetNets. With focus on green communications, we present a K−tier HetNet in which BSs are only powered by energy harvesting. Despite the uncertain nature of energy arrivals, combining two CZ techniques, namely telescopic and ON/OFF scenarios, enables us to achieve higher network performance in terms of the coverage and blocking probabilities while reducing the total power consumption and increasing the energy and spectral efficiencies.
