    This paper proposes a Cooperative ARQ protocol to be used in delay-tolerant vehicular networks. The proposed scheme has been implemented and evaluated through an experimental testbed, showing that packet losses in ...
  • A cooperative vehicular network framework 

    Trullols Cruces, Óscar; Morillo Pozo, Julián David; Barceló Ordinas, José María; García Vidal, Jorge (2009)
    Conference lecture
    Open Access
    Vehicular Ad Hoc Networks are networks characterized by intermittent connectivity and rapid changes in their topology. This paper addresses car-to-road communications in which vehicles use Access Points (AP) in a Delay ...
  • A Max coverage formulation for information dissemination in vehicular networks 

    Trullols Cruces, Óscar; Barceló Ordinas, José María; Fiore, Marco; Casetti, Claudio; Chiasserini, Carla-Fabiana (IEEE Press. Institute of Electrical and Electronics Engineers, 2009)
    Conference lecture
    Open Access
    We consider that a given number of Dissemination Points (DPs) have to be deployed for disseminating information to vehicles travelling in an urban area. We formulate our problem as a Maximum Coverage Problem (MCP) so as ...

  • Evaluation of a cooperative ARQ protocol for delay-tolerant vehicular networks 

    Morillo Pozo, Julián David; Trullols Cruces, Óscar; Barceló Ordinas, José María; García Vidal, Jorge (2008-10-16)
    Part of book or chapter of book
    Open Access
    This paper evaluates a Cooperative ARQ protocol to be used in delay-tolerant vehicular networks. The scenario consists in cars downloading information from Access Points along a road. The key difference between proposed ...
  • Exact decoding probability under random linear network coding 

    Trullols Cruces, Óscar; Barceló Ordinas, José María; Fiore, Marco (2011-01)
    Article
    Open Access
    In this letter, we compute the exact probability that a receiver obtains N linearly independent packets among K ≥ N received packets, when the sender/s use/s random linear network coding over a Galois Field of size q. Such ...
  • Generation and analysis of a large-scale urban vehicular mobility dataset 

    Uppoor, Sandesh; Trullols Cruces, Óscar; Fiore, Marco; Barceló Ordinas, José María (2014-05)
    Article
    Restricted access - publisher's policy
    The surge in vehicular network research has led, over the last few years, to the proposal of countless network solutions specifically designed for vehicular environments. A vast majority of such solutions has been evaluated ...
  • Impact of the infrastructure in mobile opportunistic networks 

    Trullols Cruces, Óscar; Morillo Pozo, Julián David; Barceló Ordinas, José María (2011)
    Conference report
    Restricted access - publisher's policy
    Epidemic modeling has been used to analyze many disciplines such as biology, ecology and medicine. In the last years, it also has been applied to networking paradigms such as social networks, virus spreading in Internet ...
  • Information dissemination in mobile networks 

    Trullols Cruces, Óscar (Universitat Politècnica de Catalunya, 2014-07-17)
    Doctoral thesis
  • Information dissemination in VANETs: deployment strategies for maximizing coverage 

    Trullols Cruces, Óscar; Barceló Ordinas, José María; Fiore, Marco; Casetti, Claudio; Chiasserini, Carla-Fabiana (2009)
    Conference lecture
    Open Access
    We consider that a given number of Dissemination Points (DPs) have to be deployed for disseminating information to vehicles travelling in an urban area. We formulate our problem as a Maximum Coverage Problem (MCP) so as ...
  • Power saving trade-offs in delay/disruptive tolerant networks 

    Trullols Cruces, Óscar; Morillo Pozo, Julián David; Barceló Ordinas, José María; García Vidal, Jorge (IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
    Conference lecture

    Wireless nodes such as smart-phones in which the WiFi wireless card is continuously on, consume battery energy in just a few hours. Moreover, in many scenarios, an always-on wireless card is useless because there is often ...
  • RSU deployment for content dissemination and downloading in intelligent transportation systems 

    Reineri, Massimo; Casetti, Claudio; Chiasserini, Carla-Fabiana; Fiore, Marco; Trullols Cruces, Óscar; Barceló Ordinas, José María (IGI Global, 2012-10-01)
