In this paper, we adopt stochastic geometry theory to analyze the optimal macro/micro BS
(base station) density for energy-efficient heterogeneous cellular networks with QoS …

Big things come in small packages; a particularly apt description of small cell deployment in
cellular networks. Small cells have a big role to play in orchestrating a cellular network that …

With the exponential increase in data traffic driven by a new generation of wireless devices,
data is expected to overwhelm cellular network capacity in the next few years. To address …

Ultra dense heterogeneous networks (HetNets), which involve densely deployed small cells
underlaying traditional macro cellular networks, will be an enabling solution for extremely …

Reducing the energy consumption of a wireless cellular network is an important and urgent
problem. This paper studies the effect of cell sizes on the energy consumed by the network …

To further improve the energy efficiency of heterogeneous networks, a separation
architecture called hyper-cellular network (HCN) has been proposed, which decouples the …
