    En este trabajo se presenta un estudio comparativo de diversos métodos para calcular la probabilidad de error en un sistema de comunicación digital por fibra óptica. Los procedimientos utilizados permiten determinar el ...
  • Analysis of the hidden and exposed terminal effects in wireless networks with cooperative ARQ 

    Alonso Zárate, Luis Gonzaga; Kormentzas, George; Verikoukis, Christos (Springer, 2010)
    Conference report

    Cooperative Automatic Retransmission Request (C-ARQ) schemes allow those users which overhear a transmission to act as spontaneous relays when a packet has been received with errors at destination. When these users ...
  • Energy efficient base station maximization switch off scheme for LTE-advanced 

    Bousia, Alexandra; Kartsakli, Elli; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2012)
    Conference report
    Restricted access - publisher's policy
    In this paper, we introduce a solution to a maximization problem for switching off Base Stations in an LTE-Advanced wireless network. Our scheme exploits the existence of idle periods in a cellular network during “night ...
  • Energy-efficient contention-aware channel selection in cognitive radio Ad-Hoc networks 

    Mesodiakaki, Agapi; Adelantado, Ferran; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2012)
    Conference report
    Restricted access - publisher's policy
    In this paper, we propose a novel contention-aware channel selection algorithm that focuses on throughput and energy efficiency improvement in Cognitive Radio Ad-Hoc Networks (CRAHNs). Specifically, we study the operation ...
  • Energy efficiency analysis of a cooperative scheme for wireless local area networks 

    Predojev, Tatjana; Alonso Zárate, Jesús; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2012)
    Conference report
    Restricted access - publisher's policy
    The Persistent Relay Carrier Sensing Multiple Access (PRCSMA) Protocol has been proposed in the literature as a Medium Access Control (MAC) protocol suitable for Cooperative Automatic Retransmission Request (C-ARQ) schemes. ...
  • Energy analysis of distributed neighbour discovery algorithms based on frame slotted-ALOHA for cooperative networks 

    Vázquez Gallego, Francisco; Alonso Zárate, Jesús; Alonso Zárate, Luis Gonzaga (2012)
    Conference report
    Restricted access - publisher's policy
    The design of communications protocols that exploit the availability of both cellular and short-range radio access interfaces in a same terminal can be exploited to improve the energy efficiency of wireless communications ...
  • Dynamic energy efficient distance-aware base station switch on/off scheme for LTE-advanced 

    Kartsakli, Elli; Bousia, Alexandra; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2012)
    Conference report
    Restricted access - publisher's policy
    Reducing the energy consumption in wireless networks has become a significant problem, not only because of its great impact on the global energy crisis, but also because it represents a noteworthy cost for telecommunication ...
  • Introduction of MPR information for enhanced multi-cluster scheduling in LTE-A uplink 

    Lema Rosas, María Ángel; García Lozano, Mario; Ruiz Boqué, Sílvia; González González, David (2013)
    Conference report
    Restricted access - publisher's policy
    Against previous Long Term Evolution (LTE) re-leases, LTE-Advanced (LTE-A) allows the use of non-contiguous resource allocation in the uplink (UL). This feature leads to an increase in spectral efficiency thanks to link ...
  • Cooperative multicast exploiting physical layer network coding: a performance analysis 

    Miliotis, Vasileios; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report
    Restricted access - publisher's policy
    In this paper, a novel cooperative scheme based on Physical layer Network Coding (PNC) for short range communication (SRC) networks is proposed. We present a scenario of overlapping networks with multicast traffic and ...
