  • Scalability of passive and active solutions for time-based ranging in IEEE 802.11 networks 

    Martín Escalona, Israel; Malpartida, Marta; Zola, Enrica Valeria; Barceló Arroyo, Francisco (Springer, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Wireless positioning systems have become popular in recent years. Outdoor positioning has been addressed successfully, but location indoors still presents some open issues. One of them is related with the scalability of ...
  • Energy efficient virtual machine consolidation under uncertain input parameters for Green Data Centers 

    Zola, Enrica Valeria; Kassler, Andreas (2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Reducing the energy consumption of data centers and the Cloud is very important in order to lower CO_2 footprint and operational cost (OPEX) of a Cloud operator. To this extent, it becomes crucial to minimise the energy ...
  • A modification of DYMO routing protocol with knowledge of nodes’ position: proposal and evaluation 

    Zola, Enrica Valeria; Barceló Arroyo, Francisco; Martín Escalona, Israel (Springer, 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Knowledge of the physical location of the nodes is known to improve performance in wireless networks. This is especially true in MANETs, where routing protocols face a continuously changing topology. In the past, routing ...
  • Mobility patterns: implications on network parameters and handover 

    Zola, Enrica Valeria (2013)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    The purpose of a wireless network is to provide coverage to mobile users (MU). Knowledge about the pattern followed by MU in a given scenario may help network planning to guarantee service along the pathway followed by ...
  • Easy Communicator: una experiencia de aprendizaje-servicio para el aprendizaje de todos 

    Guasch Murillo, Daniel; Martín Escalona, Israel (Editorial Universidad de Granada, 2015)
    Text en actes de congrés
    Accés obert
    Desde la Cátedra de Accesibilidad de la Universidad Politécnica de Cataluña se coordina el proyecto Easy Communicator con la doble finalidad de proporcionar a los estudiantes de ingeniería experiencia en el desarrollo de ...
  • A topic on simulation in telecommunications engineering 

    Barceló Arroyo, Francisco; Martín Escalona, Israel; Zola, Enrica Valeria (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Topics on network simulation are often offered as elective topics or short seminars of programs on computer sciences and telecommunications engineering. In other programs simulation is offered as part of a general core ...
  • Expected bit rate for terminals moving according to the random waypoint model in a WLAN cell 

    Zola, Enrica Valeria; Barceló Arroyo, Francisco; Kassler, Andreas; Dely, Peter (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    The IEEE 802.11 standard defines the different bit rates and modulation schemes to which a WLAN device may adapt according to the channel quality. User mobility may also have an impact on the available bit rate. This paper ...
  • Simulation of cell signalling communications using event-driven algorithms 

    Huertas Gonzalez, Daniel; Rojas Espinosa, Alfonso (2014)
    Text en actes de congrés
    Accés obert
    In this paper we present two implementations of event-driven algorithms for simulating molecular dynamics using the Omnet++ Simulation Framework and its Future Event Set (FES) implementation. The first one uses a cell-linked ...
  • Software-based system for measuring location observables in IEEE 802.11 networks 

    Martín Escalona, Israel; Barceló Arroyo, Francisco; Zola, Enrica Valeria (2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Several techniques have been proposed for positioning nodes over IEEE 802.11 networks, but only few consist in time-based multilateration, mainly due to the protocol stack not supporting accurate timestamps. One frequent ...
  • Software based measurement of round trip time observables for location in IEEE 802.11 networks 

    Martín Escalona, Israel; Barceló Arroyo, Francisco; Zola, Enrica Valeria (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Time-based multilateration in IEEE 802.11 networks usually involves custom hardware designs, which tend to slow down the implementation and deployment of the location system. This paper presents software for calculating ...
