The fifth generation (5G) mobile networks are envisioned to support the deluge of data traffic
with reduced energy consumption and improved quality of service (QoS) provision. To this …

With years of tremendous traffic and energy consumption growth, green radio has been
valued not only for theoretical research interests but also for the operational expenditure …

Traditional power grids are currently being transformed into smart grids (SGs). SGs feature
multi-way communication among energy generation, transmission, distribution, and usage …

Currently, Internet applications running on mobile devices generate a massive amount of
data that can be transmitted to a Cloud for processing. However, one fundamental limitation …

Macrocells are expected to be densely overlaid by small cells (SCs) to meet increasing
capacity demands. Due to their dense deployment, some SCs will not be connected directly …

Operators, struggling to continuously add capacity and upgrade their architecture to keep up
with data traffic increase, are turning their attention to denser deployments that improve …

Energy efficiency (EE) and spectral efficiency (SE) have been identified as key performance
indicators in the design of future cellular networks. However, the available radio frequency …

This paper studies the proposed green (energy-efficient) coverage probability, link and
network energy efficiencies in the downlink of a heterogeneous cellular network (HetNet) …

As an integration of optical fiber networks and LTE-A heterogeneous networks (HetNets),
fiber-wireless (FiWi) enhanced LTE-A HetNets will play a key role in supporting large-scale …

Heterogeneous networks (HetNets), which consist of traditional macro-cells overlaid with
newly envisioned small cells (eg, femtocells, picocells, microcells, and nanocells), are …
