    Reducing the energy consumption of data centers and the Cloud is very important in order to lower CO_2 footprint and operational cost (OPEX) of a Cloud operator. To this extent, it becomes crucial to minimise the energy ...
  • A modification of DYMO routing protocol with knowledge of nodes’ position: proposal and evaluation 

    Zola, Enrica Valeria; Barceló Arroyo, Francisco; Martín Escalona, Israel (Springer, 2015)
    Conference report
    Restricted access - publisher's policy
    Knowledge of the physical location of the nodes is known to improve performance in wireless networks. This is especially true in MANETs, where routing protocols face a continuously changing topology. In the past, routing ...
  • An empirical overview of the No Free Lunch Theorem and its effect on Real-World Machine Learning Classification 

    Gomez Guillen, David; Rojas Espinosa, Alfonso (2016-01-01)
    Open Access
    A sizable amount of research has been done to improve the mechanisms for knowledge extraction such as machine learning classification or regression. Quite unintuitively, the no free lunch (NFL) theorem states that all ...
  • Mobility patterns: implications on network parameters and handover 

    Zola, Enrica Valeria (2013)
    Conference lecture
    Restricted access - publisher's policy
    The purpose of a wireless network is to provide coverage to mobile users (MU). Knowledge about the pattern followed by MU in a given scenario may help network planning to guarantee service along the pathway followed by ...

    Zola, Enrica Valeria; Barceló Arroyo, Francisco; Kassler, Andreas (2014-11-01)
    Restricted access - publisher's policy
    The deployment of a large number of access points in public areas presents a new paradigm in which a given station may be served by more than one access point at a time. Recently, a network model has been proposed to derive ...
  • Collaborative positioning in ad hoc networks using passive time-differences of arrival 

    Martín Escalona, Israel; Barceló Arroyo, Francisco; Zola, Enrica Valeria; Ciurana Adell, Marc (Bentham Science Publishers, 2015-04-08)
    Restricted access - publisher's policy
    Accuracy and scalability contribute to the quality of location solutions in wireless networks. While accuracy is a parameter addressed in all location technologies, scalability is often relegated. However, scalability ...
