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 …

Improving the energy efficiency in telecommunication networks has been one of the main
research topics of the past few years. As a result, many energy efficient algorithms have …

Abstract We study the Short-Time Cell Outages (STCO) phenomena affecting Base Stations
(BSs) in a mobile cellular operator network. The STCO is defined as a short-time outage of …

We focus on the problem of reducing power consumption in backbone networks by putting in
sleep mode IP links in order to save energy. We propose a new algorithm, called DAFNES …

We propose a framework to manage the link lifetime in an IP backbone network by exploiting
the sleep mode (SM). In particular, when an SM feature is available, two different effects …

This paper targets the lifetime-aware management of a set of optical line amplifiers (OLAs) in
an optical network exploiting sleep mode (SM) in order to save energy. We first present a …

This paper focuses on the impact that energyefficient techniques have on the component
lifetime in optical backbone networks. The study presented in the paper considers in …

We investigate the problem of managing the lifetime of links in IP backbone networks
exploiting a sleep mode (SM) state. In particular, the SM duration tends to increase the …

Energy efficiency features are being integrated in network protocols and management
systems in order to make the infrastructure more sustainable and, at the same time, address …

Sustainable networking is becoming a paradigm for cellular operators. In this work, we study
the interplay between sleep modes and cellular network failure rates. In particular, we have …
