  • Cross-Layer radio resource allocation: the journey so far and the road ahead 

    Corvino, Virginia; Giupponi, Lorenza; Pérez Neira, Ana Isabel; Verdone, Roberto; Tralli, Velio (2009)
    Conference report
    Open Access
    The cross-layer concept originated almost ten years ago with the aim of taking the most advantage from the difficult wireless media to break the barriers imposed by the layered transmission. One of the domains where ...
  • Evaluation of spectrum opportunities in the GSM band 

    Carniani, Andrea; Giupponi, Lorenza; Verdone, Roberto; Pérez Neira, Ana Isabel (2009)
    Conference report
    Open Access
    In this paper we explore the possibility of exploiting underutilized channels in the GSM bands. The secondary (unlicensed) users of the spectrum are the nodes of an overlay cognitive ad-hoc network, which opportunistically ...
  • Fuzzy-based spectrum handoff in cognitive radio networks crowncom 

    Giupponi, Lorenza; Pérez Neira, Ana Isabel (2008)
    Conference report
    Open Access
    This paper focuses on spectrum handoffs in a cognitive radio network where secondary (unlisenced) users (i.e. cognitive radios) opportunistically use frequency channels as long as the aggregate interference caused at ...
