  • Performance analysis of a hybrid ARQ system in half duplex transmission at 2400 BPS 

    Dalmau Royo, Jordi; Serrat Fernández, Juan (IEEE IEEE, 1991)
    Text en actes de congrés
    Accés obert
    Hybrid ARQ/FEC protocols have been proposed to provide high data link integrities whilst keeping at the same time a high mean throughput rate. Nevertheless, hybrid ARQ strategies offer a lot of choices and none of them can ...
  • A stochastic optimization model for the placement of road site units 

    Urquiza Aguiar, Luis; Tripp Barba, Carolina; Aguilar Igartua, Mónica (Springer, 2015)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    In this paper, we propose a simple and scalable optimization model for the deployment of road site units (RSUs). The model takes advantage of the inherent stochasticity provided by the vehicles’ movements by using mobility ...
