  • Cooperation reliability based on reinforcement learning for cognitive radio networks 

    Vucevic, Nemanja; Akyildiz, Ian F.; Pérez Romero, Jordi (2010)
    Conference report
    Open Access
    The primary objective of cooperation in Cognitive Radio (CR) networks is to increase the efficiency and improve the network performance. However, CR users may act destructively and decrease both their own and others’ ...
  • Dynamic cooperator selection in cognitive radio networks 

    Vucevic, Nemanja; Akyildiz, Ian F.; Pérez Romero, Jordi (Elsevier, 2012-07)

    The primary objective of cooperation in cognitive radio (CR) networks is to increase the spectrum access efficiency and improve the network performance. However, Byzantine adversaries or unintentional erroneous conduct ...
  • Joint radio resource management for LTE-UMTS coexistence scenarios 

    Vucevic, Nemanja; Pérez Romero, Jordi; Sallent Roig, José Oriol; Agustí Comes, Ramon (2009)
    Conference report
    Open Access
    Constantly increasing demand for throughput and quality in wireless communication systems leads to continuous research of wise radio resource management, because of the scarce availability of frequency bands and the ...
  • Real-time HSPA emulator for end-to-edge QoS evaluation in all-IP beyond 3G heterogeneous wireless networks 

    López Benítez, Miguel; Bernardo Álvarez, Francisco; Vucevic, Nemanja; Umbert Juliana, Anna (ICST, 2008)
    Conference lecture
    Open Access
    This paper is aimed at presenting the real-time High Speed Packet Access (HSPA) emulator that has been developed in the framework of the AROMA project. Real-time emula- tors allow reproducing realistic scenarios to test ...
  • Reinforcement learning for dynamic spectrum management in WCDMA 

    Vucevic, Nemanja; Pérez Romero, Jordi; Sallent Roig, José Oriol; Agustí Comes, Ramon (2009)
    Article
    Open Access
    Low use of licensed spectrum imposes a need for the advanced spectrum management for wise spectrum usage with the release of unneeded frequency bands for the secondary markets and opportunistic access. In this paper we ...
  • 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 ...
