  • A near-optimum MAC protocol based on the distributed queueing random access protocol (DQRAP) for a CDMA mobile communication system 

    Alonso Zárate, Luis Gonzaga; Agustí Comes, Ramon; Sallent Roig, José Oriol (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2000-09)
    Article
    Open Access
    This paper presents and analyzes a new near-optimum medium access control (MAC) protocol. The proposed access scheme is suitable for a CDMA mobile communication environment, and keeps under control and upper bounded the ...
  • Análisis de un mecanismo de ahorro de energía mediante lógica fuzzy para la mejora de sistemas WLAN 802.11 

    Otal, B; Alonso Zárate, Luis Gonzaga (Univ. Jaen, 2004)
    Conference lecture

    La mayoría de los protocolos de acceso al medio, los llamados protocolos MAC (Medium Access Control), para sistemas WLAN (Wireless Local Area Network), fijan una potencia de transmisión constante sin considerar técnicas ...
  • Multiuser MAC protocols for 802.11n wireless networks 

    Kartsakli, Elli; Zorba Barah, Nizar; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2009)
    Conference lecture

    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, ...
  • The M/D/C queue with priority: application to trunked mobile radio systems 

    Barceló Arroyo, Francisco; Casares Giner, Vicente; Paradells Aspas, Josep (IEE, 1996-08)
    Article
    Restricted access - publisher's policy
    A procedure is presented for estimating the mean waiting time in an M/D/C queue with two levels of nonpre-emptive priority. The approximation gives a maximum relative error of 10% for heavy load and is greater than the ...
  • 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
    Open Access
    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 ...
