      This paper presents two novel mechanisms aimed at improving the packet transmission delay distribution and the channel usage efficiency of wireless ad hoc networks when using the DQMAN (distributed queuing MAC protocol for ...
    • Estudio del rendimiento de protocolos de acceso para redes inalámbricas con antenas direccionales 

      Alonso Zárate, Jesús; Cateura, A; Kartsakli, Elli; Verikoukis, Christos; Alonso Zárate, Luis Gonzaga (Unión Científica Internacional de Radio, 2006-09-30)

      The basic feature of the emerging high throughput IEEE 802.11n standard (and other standards) is the presence of directional antennas at network nodes. In this work, we evaluate the performance of media access control ...
    • Opportunistic scheduling for WLAN systems using cross-layer techniques and a distributed MAC 

      Cateura, A; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (Institute of Electrical and Electronics Engineers (IEEE), 2005)
      Conference lecture
