Conventional cellular systems are designed to ensure ubiquitous coverage with an always
present wireless channel irrespective of the spatial and temporal demand of service. This …

Assume that a multi-user multiple-input multiple-output (MIMO) system is designed from
scratch to uniformly cover a given area with maximal energy efficiency (EE). What are the …

Cellular network operators are always seeking to increase the area of coverage of their
networks, open up new markets and provide services to potential customers in remote rural …

Over the past couple of years, many commentators have hailed the “Internet of Things”(IoT)
as the next step in the evolution of the internet. This paper examines, from an energy …

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

Endowed with context-awareness and proactive capabilities, caching users' content locally
at the edge of the network is able to cope with increasing data traffic demand in 5G wireless …

This work proposes a distributed power allocation scheme for maximizing energy efficiency
in the uplink of OFDMA-based HetNets where a macro-tier is augmented with small cell …

Base station (BS) sleeping operation is one of the effective ways to save energy
consumption of cellular networks, but it may lead to longer delay to the customers. The …

In this paper, we study the joint pilot assignment and resource allocation for system energy
efficiency (SEE) maximization in the multi-user and multi-cell massive multi-input multi …

Most of the existing works on energy-efficient wireless communications only consider the
transmitter (Tx) or the receiver (Rx) side power consumption, but not both. Moreover, the …
