“…In this special issue, paper [159] investigates the role that cellular traffic dynamics play in efficient network energy management, and designs a framework for traffic-aware energy optimization. In particular, using a learning approach, it is shown that the C-RAN can be made aware of the near-future traffic, so that inactive or low-load BSs can be switched off, thus reducing the overall energy consumption.…”

Abstract-After about a decade of intense research, spurred by both economic and operational considerations, and by environmental concerns, energy efficiency has now become a key pillar in the design of communication networks. With the advent of the fifth generation of wireless networks, with millions more base stations and billions of connected devices, the need for energy-efficient system design and operation will be even more compelling. This survey provides an overview of energy-efficient wireless communications, reviews seminal and recent contribution to the state-of-the-art, including the papers published in this special issue, and discusses the most relevant research challenges to be addressed in the future.

“…Energy consumption is of critical interest in future 5G 121 systems [23], [24], especially in ultradense networks. Compared 122 with the power-thirsty always-on architecture, where the energy 123 consumption grows with the network's densification, the energy 124 consumption of the ultradense network relying on the dynamic 125 on-off architecture mainly depends on the density of MUs in 126 the network [2].…”

Abstract-Small-cell caching utilizes the embedded storage of 5 small-cell base stations (SBSs) to store popular contents for the 6 sake of reducing duplicated content transmissions in networks and 7 for offloading the data traffic from macrocell base stations to SBSs. 8In this paper, we study a probabilistic small-cell caching strategy, 9 where each SBS caches a subset of contents with a specific caching 10 probability. We consider two kinds of network architectures: 1) 11The SBSs are always active, which is referred to as the always-on

“…To this end, a lot of effort is being devoted in order to provide end users with ubiquitous Internet connectivity through the deployment of nextgeneration networks [3,4]. However, current network coverage is not available everywhere, anytime yet and mobile data plans, especially in scenarios of roaming between carriers, are expensive in most countries.…”

Joining a private Wi-Fi network is an intricate operation for end users, especially when they must type a long and complicated password in order to gain access. Moreover, it is often the case where users connect to multiple such hotspots, placed in public places visited in their daily routine, further exacerbating the issue.In this paper we present WPA-Totem: a small device that emits Wi-Fi configuration tokens, which can be received by any NFC-enabled smartphones and tablets. Moreover, our proposal is able to automatically change the WPA passphrase after a specified period of time, keeping away the freeloaders from the network.WPA-Totem is affordable, easy to deploy and compatible with all the existing WPA2-Personal protected Wi-Fi networks. A new client can connect to the access point by simply tapping the totem and this, as we measured, leads to a dramatic improvement of the user experience.
