  • Multiobjective auction-based switching-off scheme in heterogeneous networks: to bid or not to bid? 

    Bousia, Alexandra; Kartsakli, Elli; Antonopoulos, Angelos; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2016-11-01)
    Article
    Accés obert
    The emerging data traffic demand has caused a massive deployment of network infrastructure, including Base Stations (BSs) and Small Cells (SCs), leading to increased energy consumption and expenditures. However, the network ...
  • Resource allocation techniques for heterogeneous networks under user misbehavior 

    Miliotis, Vasileios; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2016-03)
    Article
    Accés obert
    In this letter we focus on the uplink offloading with IP Flow Mobility (IFOM). With IFOM a User Equipment (UE) is able to maintain concurrently two data streams, one through LTE and the other through WiFi. We consider the ...
  • A novel multiobjective cell switch-off framework for cellular networks 

    González González, David; Hämäläinen, Jyri; Yanikomeroglu, Halim; García Lozano, Mario; Senarath, Gamini (Institute of Electrical and Electronics Engineers (IEEE), 2016-10-25)
    Article
    Accés obert
    Cell switch-off (CSO) is recognized as a promising approach to reduce the energy consumption in the next-generation cellular networks. However, CSO poses serious challenges not only from the resource allocation perspective ...
  • Comparative study of high-performance liquid chromatography and micellar electrokinetic capillary chromatography applied to the analysis of different mixtures of pesticides 

    Farran Marsà, Adriana; Ruiz Boqué, Sílvia; Serra Coma, M.Carme; Aguilar Sanjuán, Manuel (1996-06)
    Article
    Accés restringit per política de l'editorial
    High-performance liquid chromatography (HPLC) and micellar electrokinetic capillary chromatography (MECC) methods for the determination of different pesticides mixtures have been developed. These mixtures include triazine, ...

    Article
    Accés obert
    The vision of the Internet of Things (IoT) to interconnect and Internet-connect everyday people, objects, and machines poses new challenges in the design of wireless communication networks. The design of medium access ...
  • Information exchange in randomly deployed dense WSNs with wireless energy harvesting capabilities 

    Mekikis, Podromos-Vasileos; Antonopoulos, Angelos; Kartsakli, Elli; Lalos, Aristeidis; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2016-04-01)
    Article
    Accés obert
    As large-scale dense and often randomly deployed wireless sensor networks (WSNs) become widespread, local information exchange between colocated sets of nodes may play a significant role in handling the excessive traffic ...
  • Optimization of soft frequency reuse for irregular LTE macrocellular networks 

    González González, David; García Lozano, Mario; Ruiz Boqué, Sílvia; Lee, Dong Seop (2013-05-29)
    Article
    Accés restringit per política de l'editorial
    Interference management has been recognized by the industry as a key enabler for 4G systems. Emerging technologies include multicarrier systems such as LTE and WiMAX for which effective management of intercell interference ...
  • Combining cooperation and physical layer network coding to achieve reliable multicast

    Article
    Accés restringit per política de l'editorial
    A novel cooperative scheme based on Physical layer Network Coding (PNC) for short range communication (SRC) networks is presented in this paper. We investigate a scenario of overlapping networks with multicast traffic and ...
  • Performance of Fractioned and Nonfractioned Equalizers with High-Level QAM 

    Agustí Comes, Ramon; Casadevall Palacio, Fernando José; Olmos Bonafé, Juan José (1987-04-01)
    Article
    Accés obert
    This paper presents a comparative study of 16-QAM, 32QAM, 64-QAM, and 128-QAM 140 Mbit/s digital radio in the presence of multipath fading. Conventional T -spaced and fractional tapspaced equalizers have been considered ...
  • A metaheuristic-based downlink power allocation for LTE/LTE-A cellular deployments
