  • Cooperative download in vehicular environments 

    Trullols Cruces, Óscar; Fiore, Marco; Barceló Ordinas, José María (2011-05-12)
    Article
    Restricted access - publisher's policy
    We consider a complex (i.e., nonlinear) road scenario where users aboard vehicles equipped with communication interfaces are interested in downloading large files from road-side Access Points (APs). We investigate the ...
  • Coordinated detection of forwarding faults in wireless community networks 

    López, Ester; Navarro Moldes, Leandro (2018-05-01)
    Article
    Restricted access - publisher's policy
    Wireless Community Networks (WCN) are crowdsourced networks where equipment is contributed and managed by members from a community. WCN have three intrinsic characteristics that make forwarding faults more likely: inexpensive ...
  • A lightweight service placement approach for community network micro-clouds 

    Selimi, Mennan; Cerdà Alabern, Llorenç; Freitag, Fèlix; Veiga, Luis; Sathiaseelan, Arjuna; Crowcroft, Jon (2018-02-28)
    Article
    Open Access
    Community networks (CNs) have gained momentum in the last few years with the increasing number of spontaneously deployed WiFi hotspots and home networks. These networks, owned and managed by volunteers, offer various ...
  • A stochastic approach for modeling message dissemination in opportunistic networks 

    Orozco, Javier; Santos, Rodrigo; Meseguer Pallarès, Roc; Ochoa, Sergio (2017-11)
    Article

    The opportunistic networks have shown to be an interesting communication infrastructure for supporting mobile collaborative systems in several application scenarios like disaster relief efforts, hospital work and tourism. ...
  • Real-time communication support for underwater acoustic sensor networks 

    Santos, Rodrigo; Orozco, Javier; Micheletto, Matías; Ochoa, Sergio; Meseguer Pallarès, Roc; Millán, Pere; Molina Clemente, Carlos Maria (MDPI AG, 2017-07-14)
    Article
    Open Access
    Underwater sensor networks represent an important and promising field of research due to the large diversity of underwater ubiquitous applications that can be supported by these networks, e.g., systems that deliver tsunami ...
  • 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
    Open Access
    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
    Open Access
    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
    Restricted access - publisher's policy
    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
    Open Access
    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
    Open Access
    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
    Open Access
    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
    Open Access
    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 ...
