    • A cross-layer energy-saving mechanism for an enhancement of 802.11 WLAN systems 

      Begoña, Otal; Alonso Zárate, Luis Gonzaga (Institute of Electrical and Electronics Engineers (IEEE), 2004)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Most multiple access collision avoidance-based (MAC) protocols for WLAN systems have been using fixed transmission power and have not considered energy-saving techniques targeted on channel estimation models. In order to ...
    • A new medium access protocol based on distributed queues for a CDMA environment 

      Alonso Zárate, Luis Gonzaga; Agustí Comes, Ramon; Sallent Roig, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 1999)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper presents and analyses a new stable near-optimum random access protocol. The proposed access scheme is adapted for being used in a CDMA environment. It is based on distributed queues and a collision resolution ...
    • A novel MAC protocol for dynamic ad hoc wireless networks with dynamic self-configurable master-slave architecture 

      Alonso Zárate, Jesús; Alonso Zárate, Luis Gonzaga (Suvisoft IEEE catalog number 04TH8754C, 2004)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      This paper proposes and analyses a novel MAC protocol for wireless ad hoc networks that makes use of distributed queues to achieve an efficient use of the radio channel. The protocol includes a dynamic self-configurable ...
    • Distributed point coordination function for wireless ad hoc networks 

      Crespo, Cristian; Alonso Zárate, Jesús; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2008)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper we describe a new MAC protocol for ad hoc networks called distributed point coordination function (DPCF). It constitutes an extension of the PCF of the IEEE 802.11 standard to operate over infrastructureless ...
    • Dynamic self-configurable master-slave architecture for AD HOC wireless networks with a distributed MAC scheme 

      Alonso Zárate, Jesús; Alonso Zárate, Luis Gonzaga (Institute of Electrical and Electronics Engineers (IEEE), 2004)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      This paper proposes a distributed self-configurable architecture designed for wireless mobile ad hoc networks (MANET). In this kind of network, nodes move around varying constantly the topology of the network, so it is ...
    • Fairness enhancement in a self-configuring cluster-based wireless ad hoc network 

      Alonso Zárate, Jesús; Verikoukis, Christos; Alonso Zárate, Luis Gonzaga (Institute of Electrical and Electronics Engineers (IEEE), 2005)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      In this paper we analyze an unfairness problem arisen when implementing the self-configuring clusterbased DQCA AD HOC MAC protocol in a near-static topology. When there is a low relative mobility among terminals and ...
    • Multiuser MAC protocols for 802.11n wireless networks 

      Kartsakli, Elli; Zorba Barah, Nizar; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2009)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The emerging 802.11n standard establishes the integration of MIMO technology in WLANs with the goal of achieving high data rates. However there are still many open issues regarding MAC protocol design for MIMO based systems, ...
    • Performance analysis of a distributed queuing MAC protocol for Ad-Hoc networks with different mobility conditions 

      Alonso Zárate, Jesús; Verikoukis, Christos; Alonso Zárate, Luis Gonzaga (King' s College London, 2005)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      This paper analyses the performance of the DQCA AD HOC MAC protocol for scenarios where the communication nodes have different mobility conditions, corresponding to different applications such as sensor networks, ...
    • Performance evaluation of directional antenna-assisted MAC protocols in the presence of mobility 

      Alonso Zárate, Luis Gonzaga; Verikoukis, Christos; Koutsopoulos, Iordanis (National Technical University of Athens, 2006)

    • WLAN throughput improvement via distributed queuing MAC 

      Alonso Zárate, Luis Gonzaga; Ferrús Ferré, Ramón Antonio; Agustí Comes, Ramon (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-04)
      Article
      Accés obert
      This paper analyzes the performance of a MAC scheme for wireless local area networks (WLANs) that makes use of distributed queues to improve radio channel utilization. Analytical values for the maximum throughput performance ...
