    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)
    Conference report
    Open Access
    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 ...

    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 

    Torró Vilert, Albert (Universitat Politècnica de Catalunya, 2011-05-25)
    Master thesis
    Open Access
    This project focuses on the Cognitive Radio Technology initially proposed by Joseph Mitola at the end of 90s. The concept of Cognitive Radio introduces the idea that nowadays telecommunications systems must be aware of the ...
