  • 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 ...
  • A distributed power sharing framework among households in microgrids: a repeated game approach 

    Alskaif, Tarek; Guerrero Zapata, Manel; Bellalta Jimenez, Boris; Nilsson, Anders (2017-01-01)
    Article
    Accés restringit per política de l'editorial
    In microgrids, the integration of distributed energy resources (DERs) in the residential sector can improve power reliability, and potentially reduce power demands and carbon emissions. Improving the utilization of renewable ...
  • A new approach to role and position detection in networks 

    Vega d'Aurelio, Davide; Magnani, Matteo; Montesi, Danilo; Meseguer Pallarès, Roc; Freitag, Fèlix (2016-06)
    Article
    Accés restringit per política de l'editorial
    We rethink and extend the concepts of position and role in a network, basing them on various well-known measures that were not previously associated with these concepts, such as geodesic distance and modularity. The ...
  • A MAC protocol to support monitoring of underwater spaces 

    Santos, Rodrigo; Orozco, Javier; Ochoa, Sergio; Meseguer Pallarès, Roc; Eggly, Gabriel; Pistonesi, Marcelo (2016-06-27)
    Article
    Accés obert
    Underwater sensor networks are becoming an important field of research, because of their everyday increasing application scope. Examples of their application areas are environmental and pollution monitoring (mainly oil ...

    Selimi, Mennan; Freitag, Fèlix; Cerdà Alabern, Llorenç; Veiga, Luis (Wiley, 2015-09-20)
    Article
    Accés obert
    Community networks are self-organized and decentralized communication networks built and operated by citizens, for citizens. The consolidation of today's cloud technologies offers now, for community networks, the possibility ...
  • Mobile Autonomous Sensing Unit (MASU): a framework that supports distributed pervasive data sensing 

    Medina Medina, Esunly; López Nuevo, David Andrés; Meseguer Pallarès, Roc; Ochoa, Sergio; Royo Vallés, María Dolores; Santos, Rodrigo (2016-07)
    Article
    Accés obert
    Pervasive data sensing is a major issue that transverses various research areas and application domains. It allows identifying people’s behaviour and patterns without overwhelming the monitored persons. Although there are ...
