Mobile edge computing (MEC) has been introduced to provide additional computing
capabilities at network edges in order to improve performance of latency critical applications …

The staggering growth of mobile traffic fostered by the spreading of 5G technology and
massive Internet of Things applications is leading to the need for extensive radio access …

In heterogeneous wireless networks, massive mobile terminals randomly generate a large
number of computation tasks (payloads). How to better manage these mobile terminals …

Energy consumption of wireless networks is now a very important research topic and several
research teams worldwide are proposing solutions for the so-called green wireless …

Software defined networking allows network providers to share their physical network (PN)
among multiple tenants by means of network slicing, where several virtual networks (VNs) …

The energy efficient joint source-relay power allocation problem is studied for the multi-input
multi-output (MIMO) amplify-and-forward two-hop relaying system, in which the objective of …

Cellular operators are increasingly turning toward renewable energy (RE) as an alternative
to using traditional electricity in order to reduce operational expenditure and carbon …

This paper investigates the joint transmitter and receiver optimization for the energy
efficiency (EE) in orthogonal frequency-division multiple-access (OFDMA) systems. We first …

Base station (BS) sleeping is an effective way to improve the energy-efficiency of cellular
networks. However, it may bring extra user-perceived delay. We conduct a theoretical study …

For the ambient backscatter communication system, a joint optimization algorithm based on
the energy efficiency maximization criterion was proposed in this paper by designing a two …
