    Report de recerca
    Accés obert
    We describe herein the envisioned improvements of the REMs due to advanced sensing and processing. In relation to that, we also discuss the underlying modelling assumptions. Finally, we comment on how REMs can be of use ...
  • Reinforcement learning for load management in DiffServ-MPLS mobile networks 

    Vucevic, Nemanja; Pérez Romero, Jordi; Sallent Roig, José Oriol; Agustí Comes, Ramon (2009)
    Text en actes de congrés
    Accés obert
    Cognitive networks are envisaged to provide optimized resource usage in future. While heterogeneity and resource scarcity draw research attention to the wireless part, the rest of the network (mobile backhaul) is rarely ...

  • Spectrum sharing in cognitive radio networks with imperfect sensing: a discrete-time Markov model 

    Gelabert Doran, Xavier Bernardi; Sallent Roig, José Oriol; Agustí Comes, Ramon; Pérez Romero, Jordi (2010-10)
    Accés restringit per política de l'editorial
    An efficient and utmost utilization of currently scarce and underutilized radio spectrum resources has stimulated the introduction of what has been coined Cognitive Radio (CR) access methodologies and implementations. While ...
  • Study of admission and control system in a centralized cognitive radio network for heterogeneous wireless frequency devices
