    Machine-to-Machine (M2M) networks must be energy-ef¿cient to operate autonomously for years, or even decades. In this paper, we consider a synchronized duty-cycled M2M network composed of a huge number of dormant ...
  • Constant false alarm rate control for frecuency hopping Spread Spectrum Systems 

    Agustí Comes, Ramon; Olmos Bonafé, Juan José (1989)
    Conference report
    Open Access
    A control scheme suitable for setting the false alarm rate to a fixed value in frequency hopping spread spectrum communications is proposed. the scheme performance is determined in the presence of partial band interference. ...
  • Radioenlaces digitales de gran capacidad: comportamiento del lazo recuperador de portadora en presencia de desvanecimientos selectivos 

    Olmos Bonafé, Juan José; Agustí Comes, Ramon; Casadevall Palacio, Fernando José (Consejo Superior de Investigaciones Científicas (CSIC), 1986)
    Conference report
    Open Access
    It's a known fact that in high capacity digital radio links the main cause for outage is selective fading due to multipath propagation. In this paper we present the performance of a 16QAM system which includes a high quality ...
  • Opportunistic scheduling using an enhanced channel state information update scheme for WLAN systems with DQCA 

    Higuera Portilla, Jorge Eduardo; Kartsakli, Elli; Valenzuela González, José Luis; Alonso Zárate, Luis Gonzaga (Institute of Electrical and Electronics Engineers (IEEE), 2007)

    This paper studies the feasibility of using low-power wireless technologies such as Bluetooth, IEEE 802.15.4 and ZigBee in high-speed railway scenarios that involve bidirectional ground-to-train communication. The presented ...
  • Interference coordination method for CSI improvement in LTE uplink with carrier aggregation 

    Lema Rosas, María Ángel; García Lozano, Mario; Ruiz Boqué, Sílvia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    Carrier Aggregation is an important feature in Long Term Evolution Advanced (LTE-A). It allows operators to provide larger operational bandwidths without the need of having a contiguous, large piece of spectrum. However, ...
  • Trimming the power consumption of domestic Wi-Fi networks: how much power does your router need? 

    Pérez Díaz de Cerio, David; González Rodríguez, Marta; Valenzuela González, José Luis; González Arbesú, José María (2015)
    Conference report

    This work is part of a project where the goals are: designing energetically-optimum domestic WiFi routers; obtaining real and accurate power consumed models as a function of router configuration, and providing the ...
  • Massive access in the random access channel of LTE for M2M communications: an energy perspective 

    Laya, Andrés; Alonso-Zárate, Jesús; Alonso Zárate, Luis Gonzaga; Chatzimisios, Periklis (2015)
    Conference report
    Restricted access - publisher's policy
    The capacity limits of the Random Access Channel (RACH) of Long Term Evolution (LTE) for highly dense Machineto-Machine communications are studied in this paper. We consider the case study when a high number of devices ...
  • Reservation dynamic frame slotted-ALOHA for wireless M2M networks with energy harvesting 

    Vázquez-Gallego, Francisco; Alonso-Zárate, Jesús; Alonso Zárate, Luis Gonzaga (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Restricted access - publisher's policy
    We consider a wireless Machine-to-Machine (M2M) area network where a gateway periodically collects data from a group of end-devices equipped with energy harvesters. While the use of energy harvesters ideally provides ...
  • Combating selfish misbehavior with reputation based uplink offloading for IP flow mobility 

    Miliotis, Vasileios; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2015)
    Conference report
    Restricted access - publisher's policy
    In this paper we focus on the uplink offloading based on IP Flow Mobility (IFOM). With IFOM a User Equipment (UE) is able to maintain concurrently two data streams, one through LTE and the other through WiFi. We propose a ...
  • On the mobility of moderate speed users in ultra dense small cell deployments with mmW 

    Joud, Mohammad; García Lozano, Mario; Ruiz Boqué, Sílvia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference lecture
    Restricted access - publisher's policy
    This paper deals with mobility robustness in a context of ultra-dense deployments operating at the millimeter wave (mmW) band. In order to increase the threshold speed of user equipments (UEs) allowed at the small cell ...
