    This paper presents a viewpoint of the management for the Future Internet. For this description we consider the architectural model developed by the EU IST Autonomic Internet – AUTOI – consortium for the management ...
  • A multi-user game-theoretical multipath routing protocol to send video-warning messages over mobile ad hoc networks 

    Mezher Mezher, Ahmad; Aguilar Igartua, Mónica; Cruz Llopis, Luis Javier de la; Pallarès Segarra, Esteve; Tripp Barba, Carolina; Urquiza Aguiar, Luis; Fornés Guardia, Jordi; Sanvicente Gargallo, Emilio (2015-04-17)
    Article
    Open Access
    The prevention of accidents is one of the most important goals of ad hoc networks in smart cities. When an accident happens, dynamic sensors (e.g., citizens with smart phones or tablets, smart vehicles and buses, etc.) ...
  • Estudio de la congestion en subcanales HF en un enlace entre Madrid y Barcelona

  • Algoritmo para optimizacion de la transferencia de datos libres de errores en canales H.F 

    Valle Alarcón, Rafael; Dalmau Royo, Jordi (1991)
    Conference report
    Open Access
    We present a research on error-free data transmission in H.F. radio communications. In concrete, a study on the C.C.I.T.T. recomendation V.42 and a evaluation of the optimal frame length vs. average b.e.r. of th H. F . ...
  • Comportamiento de un protocolo ARQ en canal de hf a 2400 bps 

    Serrat Fernández, Juan; Dalmau, Jordi (1991)
    Conference report
    Open Access
    Today HF communication systems rely on the concept of adaptation. In fact, the benefits of exploiting the time/frequency variant capacity of the HF channel have been reported elsewhere. Adaptive systems can play an important ...
