    • A multiobjective wavelength routing approach combining network and traffic engineering with energy awareness 

      Palmieri, Francesco; Ricciardi, Sergio; Fiore, Ugo; Castiglione, Aniello; Careglio, Davide (2017-12-01)
      Article
      Open Access
      In modern optical networks, infrastructure management is faced with the challenge of using expensive equipment and communication resources as efficiently as possible. This now includes keeping power consumption costs at a ...

    • Energy-oriented denial of service attacks: an emerging menace for large cloud infrastructures 

      Palmieri, Francesco; Ricciardi, Sergio; Fiore, Ugo; Ficco, Massimo; Castiglione, Aniello (2015-05-01)
      Article
      Open Access
      This work analyzes a new and very subtle kind of security threat that can affect large-scale cloud-based IT service infrastructures, by exploiting the computational resources of their component data center to waste as much ...

    • Energy-oriented models for WDM networks 

      Ricciardi, Sergio; Careglio, Davide; Palmieri, Francesco; Fiore, Ugo; Santos Boada, Germán; Solé Pareta, Josep (2010)
      Conference report
      Open Access
      A realistic energy-oriented model is necessary to formally characterize the energy consumption and the consequent carbon footprint of actual and future high-capacity WDM networks. The energy model describes the energy ...

    • Evaluating energy savings in WoL-enabled networks of PCs 

      Ricciardi, Sergio; Santos Boada, Germán; Careglio, Davide; Palmieri, Francesco; Fiore, Ugo (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Restricted access - publisher's policy
      In this paper we present EnergySave, a smart energy-saving system that, by leveraging the consolidated WoL (Wake on LAN) technology, allows the remote wake-up of PCs from a centralized management server, providing easy and ...

    • Evaluating network-based DoS attacks under the energy consumption perspective: new security issues in the coming green ICT area 

      Palmieri, Francesco; Ricciardi, Sergio; Fiore, Ugo (2011)
      Conference report
      Restricted access - publisher's policy
      In the green Information and Communication Society (ICS), new form of Denial of Service (DoS) attacks may be put in place: exploiting the computational and storage resources of datacenters with the aim of consuming as much ...

    • Modeling energy consumption in next-generation wireless access-over-WDM networks with hybrid power sources 

      Ricciardi, Sergio; Palmieri, Francesco; Fiore, Ugo; Castiglione, Aniello; Santos Boada, Germán (2013-09)
      Article
      Restricted access - publisher's policy
      Energy consumption is now one of the most important issues for network carriers, since the majority of the energy needed for their operation is consumed in the wireless access and optical transport networks. The continuous ...

    • Planning and operational energy optimization solutions for smart buildings 

      Sembroiz Ausejo, David; Careglio, Davide; Ricciardi, Sergio; Fiore, Ugo (2019-02)
      Article
      Open Access
      The incremented popularity of Internet of Things (IoT), thanks to improvements both in hardware and software of sensors over the last years, enables the possibility to monitor and gather any kind of data. Additionally, the ...

    • Saving energy in data center infrastructures 

      Ricciardi, Sergio; Careglio, Davide; Santos Boada, Germán; Solé Pareta, Josep; Fiore, Ugo; Palmieri, Francesco (2011)
      Conference report
      Restricted access - publisher's policy
      At present, data centers consume a considerable percentage of the worldwide produced electrical energy, equivalent to the electrical production of 26 nuclear power plants, and such energy demand is growing at fast pace due ...
