      Cross-Layer optimization is an emerging research topic. This paper proposes two novel cross-layer mechanisms to be included in a WLAN system where a near-optimum distributed MAC protocol is used. Their performance in terms ...

    • Cross-layer enhancement for WLAN systems with heterogeneous traffic based on DQCA

      Voice transmission over WLAN and cross-layer optimization are emerging research topics. This paper proposes two novel cross-layer mechanisms for a WLAN system where the offered traffic is of mixed nature (voice and data) ...

    • Enhanced operation of DQMAN based wireless ad hoc networks 

      Alonso Zárate, Jesús; Kartsakli, Elli; Cateura, A; Verikoukis, Christos; Alonso Zárate, Luis Gonzaga (Institute of Electrical and Electronics Engineers (IEEE), 2007-10-01)

      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)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      This paper proposes a novel Cross-Layer optimization mechanism for WLAN systems and analyses its performance in terms of throughput and mean packet delay. The proposed scheme makes use of a MAC-PHY interaction and a ...
