  • Sensitivity of Aquarius active and passive measurements temporal covariability to land surface characteristics 

    Piles Guillem, Maria; McColl, Kaighin A.; Entekhabi, Dara; Das, Narendra; Pablos Hernández, Miriam (Institute of Electrical and Electronics Engineers (IEEE), 2015-03-16)
    Article
    Open Access
    Active and passive microwave observations over land are affected by surface characteristics in different ways. L-band radar backscatter and radiometer measurements each have distinct advantages and problematic issues when ...
  • First polarimetric GNSS-R measurements from a stratospheric flight over boreal forests 

    Carreño Luengo, Hugo; Amézaga Sarries, Adrià; Vidal Mateu, David; Olivé Muñiz, Roger; Muñoz Martin, Joan Francesc; Camps Carmona, Adriano José (2015-01-01)
    Article
    Open Access
    The first-ever dual-frequency multi-constellation Global Navigation Satellite Systems Reflectometry (GNSS-R) polarimetric measurements over boreal forests and lakes from the stratosphere are presented. Data were collected ...
  • Using annotations on Mechanical Turk to perform supervised polarity classification of Spanish customer comments 

    Ruiz Costa-Jussà, Marta; Grivolla, Jens; Mellebeek, Bart; Benavent, Francesc; Codina, Joan; Codina, Joan; Banchs, Rafael (2014-12-01)
    Article
    Restricted access - publisher's policy
    One of the major bottlenecks in the development of data-driven AI Systems is the cost of reliable human annotations. The recent advent of several crowdsourcing platforms such as Amazon’s Mechanical Turk, allowing requesters ...
  • Optimal virtual slice composition toward multi-tenancy over hybrid OCS/OPS data center networks 

    Pagès Cruz, Albert; Pérez Sanchis, Miguel; Peng, Shuping; Perelló Muntan, Jordi; Simeonidou, Dimitra; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2015-10-01)
    Article
    Open Access
    Multi-tenancy is a key feature of modern data centers. It allows for the existence of multiple independent virtual infrastructures, called virtual slices, on top of the same physical infrastructure, each of them specially ...
  • SDN-enabled OPS with QoS guarantee for reconfigurable virtual data center networks 

    Miao, Wang; Agraz Bujan, Fernando; Peng, Shuping; Spadaro, Salvatore; Bernini, Giacomo; Perelló Muntan, Jordi; Zervas, Georgios; Nejabati, Reza; Ciulli, Nicola; Simeonidou, Dimitra; Dorren, Harm; Calabretta, Nicola (Institute of Electrical and Electronics Engineers (IEEE), 2015-07-01)
    Article

    Optical packet switching (OPS) can enhance the performance of data center networks (DCNs) by providing fast and large-capacity switching capability. Benefiting from the software-defined networking (SDN) control plane, which ...
  • On the use of radio environment maps for interference management in heterogeneous networks 

    Pérez Romero, Jordi; Zalonis, Andreas; Boukhatem, Lila; Kliks, Adrian; Koutlia, Aikaterini; Dimitriou, Nikos; Kurda, Reben (2015-08-01)
    Article
    Open Access
    This article addresses the use of REMs to support interference management optimization in heterogeneous networks composed of cells of different sizes and including both cellular and non-cellular (e.g. WiFi) technologies. ...
  • Cooperative energy harvesting-adaptive MAC protocol for WBANs 

    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 ...
  • Multi-tenant software-defined hybrid optical switched data centre 

    Peng, Shuping; Guo, Bingli; Jackson, Chris; Najabati, Reza; Agraz Bujan, Fernando; Spadaro, Salvatore; Bernini, Giacomo; Ciulli, Nicola; Simeonidou, Dimitra (2015-08-01)
    Article
    Open Access
    We introduce a holistic solution for software-defined optical data centres (DC). Hybrid optical circuit/packet switching technologies are employed in the data plane, while a software-defined networking (SDN) controller ...
