Cooperative download in vehicular environments
Trullols Cruces, Óscar; Fiore, Marco; Barceló Ordinas, José María (2011-05-12)
Article
Accés restringit per política de l'editorialWe consider a complex (i.e., nonlinear) road scenario where users aboard vehicles equipped with communication interfaces are interested in downloading large files from road-side Access Points (APs). We investigate the ... -
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)
Capítol de llibre
Accés obertThis 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
Accés obertIn 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
Accés restringit per política de l'editorialThe 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 ... -
