    Esteves, Volker; Antonopoulos, Angelos; Kartsakli, Elli; Puig Vidal, Manel; Miribel Català, Pere Lluís; Verikoukis, Christos (2015-06-01)
    Article
    Open Access
    In this paper, we introduce a cooperative medium access control (MAC) protocol, named cooperative energy harvesting (CEH)-MAC, that adapts its operation to the energy harvesting (EH) conditions in wireless body area networks ...
  • Provisioning vehicular services and communications based on a bluetooth sensor network deployment 

    Pérez Díaz de Cerio, David; Valenzuela González, José Luis (2015-06-01)
    Article
    Open Access
    It is very common to rule out Bluetooth as a suitable technology for vehicular communications. The reasons behind this decision usually result from misconceptions such as accepting that Bluetooth has a short application ...
  • RLNC-aided cooperative compressed sensing for energy efficient vital signal telemonitoring 

    Lalos, Aristeidis; Antonopoulos, Angelos; Kartsakli, Elli; Di Renzo, Marco; Tennina, Stefano; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2015-07-01)
    Article
    Open Access
    Wireless body area networks (WBANs) are composed of sensors that either monitor and transmit vital signals or act as relays that forward the received data to a body node coordinator (BNC). In this paper, we introduce an ...
  • MPR-aware scheduler for carrier aggregation transmissions in LTE uplink 

    Lema Rosas, María Ángel; García Lozano, Mario; Ruiz Boqué, Sílvia (2015-09-01)
    Article
    Restricted access - publisher's policy
    Unlike previous Long Term Evolution (LTE) releases, LTE - Advanced (LTE-A) allows the use of non-contiguous resource allocation in the uplink (UL). This feature leads to increase the spectral efficiency thanks to link ...
  • Energy-efficient infrastructure sharing in multi-operator mobile networks 

    Antonopoulos, Angelos; Kartsakli, Elli; Bousia, Alexandra; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2015-05-01)
    Article
    Open Access
    Network infrastructure sharing and base station switching off mechanisms have been recently introduced as promising solutions toward energy and cost reduction in cellular networks. Although these techniques are usually ...
  • Attitude estimation for in-service base station antenna using downlink channel fading statistics 

    Ling, Cen; Yin, Xuefeng; Yongyu, He; Ruiz Boqué, Sílvia (2015-01-01)
    Article
    Open Access
    Amaximum-likelihood-estimation method is proposed for extracting the attitude of a sectoring base station (BS) antenna by using the received signal strengths observed by multiple user equipments (UEs) in this contribution. ...
  • Energy analysis of contention tree-based access protocols in dense machine-to-machine area networks 

    Vázquez-Gallego, Francisco; Alonso Zárate, Luis Gonzaga; Alonso-Zárate, Jesús (2015-04-23)
    Article
    Open Access
    Machine-to-Machine (M2M) area networks aim at connecting an M2M gateway with a large number of energy-constrained devices that must operate autonomously for years. Therefore, attaining high energy efficiency is essential ...
  • Power minimization of cooperative beamforming networks with spectrum sharing 

    Ling, Cen; Yin, Xuefeng; Ruiz Boqué, Sílvia; García Lozano, Mario (2015-03-13)
    Article
    Open Access
    Cooperative communication with spectrum sharing has been proved to be an efficient way to reduce energy consumption. In this work, an optimal power allocation algorithm is proposed for mobile cooperative beamforming networks, ...
  • HEH-BMAC: hybrid polling MAC protocol for WBANs operated by human energy harvesting 

    Ibarra, Ernesto; Antonopoulos, Angelos; Kartsakli, Elli; Verikoukis, Christos (2015-02-01)
    Article
    Open Access
    This paper introduces human energy harvesting medium access control (MAC) protocol (HEH-BMAC), a hybrid polling MAC suitable for wireless body area networks powered by human energy harvesting. The proposed protocol combines ...
  • A traffic aware energy saving scheme for multicarrier HSPA+ 

    Jada, Maliha Urooj; García Lozano, Mario; Hämäläinen, Jyri (Springer, 2015-02-16)
    Article
    Open Access
    In the near future, an increase in cellular network density is expected to be one of the main enablers for the newly introduced challenging capacity goals. This development will lead to an increase in the network energy ...
