    • Dimensioning cellular networks with fixed relay stations 

      Vidal Manzano, José; Marina, Ninoslav; Host-Madsen, Anders (2008)
      Text en actes de congrés
      Accés obert
      We analyze the downlink spectral efficiency of multicellular wireless networks where in each cell in addition to the base station (BS) a certain number of relay stations (RS) are deployed. It is observed that by introducing ...

    • Route change latency in low-power and lossy wireless networks using RPL and 6LoWPAN neighbor discovery 

      Kermajani, Hamidreza; Gómez Montenegro, Carlos (2011)
      Text en actes de congrés
      Accés obert
      The IETF ROLL WG is currently in the final steps of the specification of RPL, a new routing protocol for low power and lossy networks (e.g. wireless sensor networks). RPL may use layer two- and layer three-based mechanisms ...

    • Upper nound on outage capacity of orthogonal relay networks 

      Pérez Neira, Ana Isabel; Gómez Vilardebó, Jesús (2006)
      Text en actes de congrés
      Accés obert
      We consider the orthogonal multiple relay channel at the low SNR regime.The source transmits to the destination and all the possible relays in one channel and the relays transmit in different and orthogonal channels ...

    • User allocation algorithm with rate guarantees for multi-rate mobile networks with Backhaul Constraints 

      Galeana Zapién, Hiram; Lainz, Anna; Ferrús Ferré, Ramón Antonio (2009-04)
      Text en actes de congrés
      Accés obert
      The optimization of the base station (BS) assignment problem in mobile access networks is a primary task towards enabling efficient utilization of network resources. So far, this problem has been mainly studied in terms ...
