A detailed survey of approaches reducing energy consumption of core networks is
presented in this paper. We consider a multilayer architecture, in which the optical layer can …

The power consumption in Information and Communication Technologies networks is
growing year by year; this growth presents challenges from technical, economic, and …

In this paper, we present a dynamic energy efficient routing and spectrum assignment
algorithm with regenerator placement (RP) capability for elastic optical networks. In this …

Routers and switches are major contributors to the energy consumption of modern networks.
Today, many energy efficiency metrics for these high-capacity devices are coarse-grained …

Abstract Device-to-device (D2D)-aided fog network has proven to be a viable means to
improve the performance of fog computing technology. To exploit the full potentials of the …

The amount of data moved over the Internet per year has already exceeded the Exabyte
scale and soon will hit the Zettabyte range. To support this massive amount of data …

The well known cloud computing is being extended by the idea of fog with the computing
nodes placed closer to end users to allow for task processing with tighter latency …

In this work we propose a strategy to minimize the impact of energy saving techniques on
the performance of an Internet Service Provider network. We study the problem of putting in …

The widespread proliferation of Internet and wireless applications has produced a significant
increase of ICT energy footprint. As a response, in the last years, significant efforts have …

In order to optimize energy efficiency, network operators try to switch off as many network
devices as possible. Recently, there is a trend to introduce content caches as an inherent …
