    In the coming years, planning future mobile networks will be infinitely more complex than nowadays. Future networks are expected to present multiple Network Management (NM) challenges to operators, such as managing network ...
  • Self coordination among SON functions in LTE heterogeneous networks 

    Moysen Cortes, Jessica; Giupponi, Lorenza (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Restricted access - publisher's policy
    In a self-organized Long Term Evolution (LTE) network, different Self-Organizing Network (SON) functions or different instances of the same SON function can execute parallel actions, which interact or collide among each ...
  • Predicting QoS in LTE HetNets based on location-independent UE measurements 

    Moysen Cortes, Jessica; Giupponi, Lorenza; Baldo, Nicola; Mangues Bafalluy, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Restricted access - publisher's policy
    This paper aims to find patterns of knowledge from physical layer data coming from Heterogeneous Long Term Evolution (LTE) networks. We discuss how the collected data is employed in such a manner that improves Minimization ...
  • On the potential of ensemble regression techniques for future mobile network planning 

    Moysen Cortes, Jessica; Giupponi, Lorenza; Mangues Bafalluy, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference report
    Restricted access - publisher's policy
    Planning of current and future mobile networks is becoming increasingly complex due to the heterogeneity of deployments, which feature not only macrocells, but also an underlying layer of small cells whose deployment is ...
  • Bluetooth Low Energy sensor networks for railway applications 

    Hernandez Solana, Angela; Valdovinos, Antonio; Pérez Díaz de Cerio, David; Valenzuela González, José Luis (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference lecture
    Open Access
    This paper analyzes the viability of Bluetooth Low Energy (BLE) as the enabling technology in railway scenarios to allow sensor data transmission from ground to train. This proposal is based on using the broadcasting ...
  • Combining distributed queuing with energy harvesting to enable perpetual distributed data collection applications 

    Vázquez-Gallego, Francisco; Tuset-Peiro, Pere; Alonso Zárate, Luis Gonzaga; Alonso Zárate, Jesús (Wiley-Blackwell, 2017-05-12)
    Article
    Open Access
    This paper presents, models, and evaluates energy harvesting–aware distributed queuing (EH-DQ), a novel medium access control protocol that combines distributed queuing with energy harvesting (EH) to address data collection ...
  • Energy and spectrum efficient user association in millimeter wave backhaul small cell networks 

    Mesodiakaki, Agapi; Adelantado Freixer, Ferran; Alonso Zárate, Luis Gonzaga; Di Renzo, Marco; Verikoukis, Christos (2017-02)
    Article
    Open Access
    Macrocells are expected to be densely overlaid by small cells (SCs) to meet increasing capacity demands. Due to their dense deployment, some SCs will not be connected directly to the core network, and thus, they may forward ...
  • Cooperation incentives for multi-operator C-RAN energy efficient sharing 

    Vincenzi, Matteo; Antonopoulos, Angelos; Kartsakli, Elli; Vardakas, John; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
