Graphene is an ideal material for optoelectronic applications. Its photonic properties give
several advantages and complementarities over Si photonics. For example, graphene …

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 …

Traffic in communication networks fluctuates heavily over time. Thus, to avoid capacity
bottlenecks, operators highly overestimate the traffic volume during network planning. In this …

The year-by-year increase in electricity consumption significantly affects all nations today
from environmental, social, and economic perspectives. Various studies show that, among …

In this paper we study the cost-optimal deployment of optical access networks considering
variants of the problem such as fiber to the home (FTTH), fiber to the building (FTTB), fiber to …

With the development of IP networks and intelligent optical switch networks, the backbone
network tends to be a multi-granularity transport one. In a multi-granularity transport network …

Energy consumption of large-scale networks has become a primary concern in a society
increasingly dependent on information technology. Novel solutions that contribute to …

Energy consumption and energy efficiency of telecommunication networks are important for
network operators regarding both, cost and sustainability aspects. Among several options …

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

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 …
