    In this paper, we evaluate a novel contention-aware channel selection algorithm that focuses on energy efficiency improvement of a secondary network (SN) in a scenario where other non-cooperating SNs are also using the ...
  • Energy-efficient user association in cognitive heterogeneous networks 

    Mesodiakaki, Agapi; Adelantado Freixer, Ferran; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2014-07)
    Article
    Restricted access - publisher's policy
    Due to the ever increasing data traffic demands, which are directly connected to increased energy consumption, it becomes challenging for operators to achieve capacity enhancement while limiting their electric bill. To ...
  • Nonuniform traffic distribution model in reverse link of multilaterate/multiservie WCDMA/based systems 

    Adelantado Freixer, Ferran; Pérez Romero, Jordi; Sallent Roig, José Oriol (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-09)
    Article
    Open Access
    This paper focuses on the modeling of the reverse link of a wideband code division multiple access system in a nonhomogeneous environment with a single cell. Multiple traffic spatial and service nonuniformities are considered ...
  • Using simulation to provide alternative solutions to the flowshop sequencing problem 

    Juan Pérez, Angel Alejandro; Guix, Antoni; Adelantado Freixer, Ferran; Fonseca Casas, Pau; Ruiz García, Rubén (2010)
    Conference report
    Open Access
    In this paper we present SS-GNEH, a simulation-based algorithm for the Permutation Flowshop Sequencing Problem (PFSP). Given a PFSP instance, the SSGNEH algorithm incorporates a randomness criterion to the classical NEH ...
