  • A DRAM/SRAM memory scheme for fast packet buffers 

    García Vidal, Jorge; March, Maribel; Cerdà Alabern, Llorenç; Corbal San Adrián, Jesús; Valero Cortés, Mateo (2006-05)
    Article
    Accés obert
    We address the design of high-speed packet buffers for Internet routers. We use a general DRAM/SRAM architecture for which previous proposals can be seen as particular cases. For this architecture, large SRAMs are needed ...
  • Advances in wireless community networks with the community-lab testbed 

    Navarro Moldes, Leandro; Baig Viñas, Roger; Barz, Christoph; Bonicioli, Joseph; Braem, Bart; Freitag, Fèlix; Vilalta i Balaguer, Ivan (2016-07)
    Article
    Accés obert
    Beyond traditional telecom providers, citizens and organizations pool their own resources and coordinate in order to build local network infrastructures to address the digital divide in many parts of the world. These ...
  • Leveraging deployment models on low-resource devices for cloud services in community networks 

    Silvestre Apolonia, Nuno Miguel; Freitag, Fèlix; Navarro Moldes, Leandro (2016-07)
    Article
    Accés restringit per política de l'editorial
    Community networks are crowd-sourced IP networks that evolved into regional-scale computing platforms. This has led to adapting the cloud computing model for services that can operate and use computing resources inside a ...
  • guifi.net, a crowdsourced network infrastructure held in common 

    Baig Viñas, Roger; Roca Tió, Ramon; Freitag, Fèlix; Navarro Moldes, Leandro (2015-10-29)
    Article
    Accés obert
    The expression “crowdsourced computer networks” refers to a network infrastructure built by citizens and organisations who pool their resources and coordinate their efforts to make these networks happen. “Community networks” ...
  • Sustainability and participation in the digital commons 

    Franquesa Griso, David; Navarro Moldes, Leandro (2017-05-01)
    Article
    Accés obert
    In this forum we highlight innovative thought, design, and research in the area of interaction design and sustainability, illustrating the diversity of approaches across HCI communities.
  • Enhanced geometries of macroporous silicon photonic crystals for optical gas sensing applications 

    Cardador Maza, David; Vega d'Aurelio, Davide; Segura García, Daniel; Todorov Trifonov, Trifon; Rodriguez, Albert (2017-07-01)
    Article
    Accés obert
    A macroporous silicon photonic crystal is designed and optimized theoretically for its use in gas sensing applications and IR optical filters. Light impinges perpendicularly onto the sample surface (vertical propagation) ...
  • Game theory framework for MAC parameter optimization in energy-delay constrained sensor networks 

    Doudou, Messaoud; Barceló Ordinas, José María; Djenouri, Djamel; García Vidal, Jorge; Bouabdallah, Abdelmadjid; Badache, Nadjib (2016-05)
    Article
    Accés obert
    Optimizing energy consumption and end-to-end (e2e) packet delay in energy-constrained, delay-sensitive wireless sensor networks is a conflicting multiobjective optimization problem. We investigate the problem from a game ...
  • Reputation-based joint scheduling of households appliances and storage in a microgrid with a shared battery 

    Alskaif, Tarek; Luna, Adriana C.; Guerrero Zapata, Manel; Guerrero, Josep M.; Bellalta Jimenez, Boris (2017-03-01)
    Article
    Accés restringit per política de l'editorial
    Due to the decreasing revenues from the surplus renewable energy injected into the grid, mechanisms promoting self-consumption of this energy are becoming increasingly important. Demand response (DR) and local storage are ...
  • Energy efficiency of MAC protocols in low data rate wireless multimedia sensor networks: A comparative study 

    Alskaif, Tarek; Bellalta Jimenez, Boris; Guerrero Zapata, Manel; Barceló Ordinas, José María (Elsevier, 2017-03-01)
    Article
    Accés restringit per política de l'editorial
    Some new application scenarios for Wireless Sensor Networks (WSNs) such as urban resilience, smart house/building, smart agriculture and animal farming, among others, can be enhanced by adding multimedia sensors able to ...
  • Providing behaviour awareness in collaborative project courses 

    Medina Medina, Esunly; Meseguer Pallarès, Roc; Ochoa, Sergio; Medina, Humberto (2016-10-01)
    Article
    Accés obert
    Several studies show that awareness mechanisms can contribute to enhance the collaboration process among students and the learning experiences during collaborative project courses. However, it is not clear what awareness ...
