    • Mean waiting time in the M/H2/s queue: application to mobile communications Systems 

      Barceló Arroyo, Francisco; Paradells Aspas, Josep; Aguilar Igartua, Mónica (Wissenschaft & Technik, 1997)
      Conference lecture
      Open Access
      In this paper a procedure to approximately calculate the mean waiting time in the M/H2/s queue is presented. The approximation is heuristic although based in the intuitive symmetry between the deterministic and balanced ...
    • Robust optimization for energy-efficient virtual machine consolidation in modern datacenters 

      Nasim, Robayet; Zola, Enrica Valeria; Kassler, Andreas (SpringerLink, 2018-04-28)
      Article
      Open Access
      Energy efficient virtual machine (VM) consolidation in modern data centers is typically optimized using methods such as Mixed Integer Programming, which typically require precise input to the model. Unfortunately, many ...
    • Optimal user association, backhaul routing and switching off in 5G heterogeneous networks with mesh millimeter wave backhaul links 

      Mesodiakaki, Agapi; Zola, Enrica Valeria; Santos, Ricardo; Kassler, Andreas (Elsevier, 2018-05-26)
      Article
      Open Access
      Next generation, i.e., fifth generation (5G), cellular networks will provide a significant higher capacity per area to support the ever-increasing traffic demands. In order to achieve that, many small cells need to be ...

    • A fast robust optimization-based heuristic for the deployment of green virtual network functions 

      Marotta, Antonio; Zola, Enrica Valeria; D'Andreagiovanni, Fabio; Kassler, Andreas (2017-10-01)
      Article
      Open Access
      Network Function Virtualization (NFV) has attracted a lot of attention in the telecommunication field because it allows to virtualize core-business network functions on top of a NFV Infrastructure. Typically, virtual network ...
    • A meta-analysis on classification model performance in real-world datasets: an exploratory view 

      Gómez Guillen, David; Rojas Espinosa, Alfonso (2018-02-22)
      Article
      Restricted access - publisher's policy
      The No Free Lunch (NFL) Theorem imposes a theoretical restriction on optimization algorithms and their equal average performance on different problems, under some particular assumptions. Nevertheless, when brought into ...
    • Implementation and performance assessment of location-based routing protocols for MANETs 

      Martín Escalona, Israel; Zola, Enrica Valeria; Perrone, Fabio; Barceló Arroyo, Francisco; Machado Sánchez, Sergio (Association for Computing Machinery (ACM), 2017)
      Conference lecture
      Restricted access - publisher's policy
      Mobile ad-hoc networking is a topic that has caught the interest of the research community for years. Although MANETs were introduced time ago, routing in such difficult environments is still an open issue. Routing protocols ...

      Open Access
      Fifth generation (5G) wireless networks will target at energy and spectrum efficient solutions to cope with the increasing demands in capacity and energy efficiency. To achieve this joint goal, dense networks of small ...
    • Impact of unreliable positioning in location-based routing protocols for MANETs 

      Martín Escalona, Israel; Perrone, Fabio; Zola, Enrica Valeria; Barceló Arroyo, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference report
      Restricted access - publisher's policy
      MANETs have been focusing the interest of researchers for several years. The new scenarios where MANETs are being deployed make that several challenging issues remain open: node scalability, energy efficiency, network ...
    • DYMO self-forwarding: a simple way for reducing the routing overhead in MANETS 

      Zola, Enrica Valeria; Barceló Arroyo, Francisco; Martín Escalona, Israel (HINDAWI, 2017-01-01)
      Article
      Open Access
      Current routing protocols in Mobile Ad hoc Networks tend to use information on the position of the nodes in order to improve their features. In fact, without this information, protocols are hardly scalable since they tend ...
