    • Impact of correlated log-normal shadowing on two-way network coded cooperative wireless networks 

      Lalos, Aristeidis; Di Renzo, Marco; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2013-09)
      Article
      Accés restringit per política de l'editorial
      In this letter, we provide a novel theoretical framework for studying the effects of correlated shadowing, in the number of relays that are capable of helping two nodes (sources) to exchange their messages. The relays use ...
    • Machine-to-machine (M2M) communications for e-health applications 

      Kartsakli, Elli; Lalos, Aristeidis; Antonopoulos, Angelos; Tennina, Stefano; Di Renzo, Marco; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (Elsevier, 2015)
      Capítol de llibre
      Accés obert
      The emerging technology of machine-to-machine (M2M) communications is bringing a paradigm shift in healthcare delivery. A broad range of e-health applications can be conceived, with considerable benefits for both patients ...
    • On the impact of shadowing on the performance of cooperative medium access control protocols 

      Di Renzo, Marco; Alonso Zárate, Jesús; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (IEEE, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Accurate representation of the physical layer is instrumental for a sound design and optimization of Medium Access Control (MAC) protocols for cooperative wireless networks. However, the vast majority of MAC protocols ...
    • Performance analysis of antenna subset selection in space shift keying systems 

      Ntontin, Konstantinos; Di Renzo, Marco; Pérez Neira, Ana Isabel; Verikoukis, Christos (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, we provide a performance analysis of closed-loop antenna subset selection in Space Shift Keying (SSK) systems. In particular, we provide a closed-form formula for the Symbol Error Rate (SER) of such systems, ...
    • Performance analysis of multistream spatial modulation with maximum-likelihood detection 

      Ntontin, Konstantinos; Di Renzo, Marco; Pérez Neira, Ana Isabel; Verikoukis, Christos (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, we provide a theoretical analysis of the optimal Maximum-Likelihood (ML) detector for the recently proposed multistream Spatial Modulation (SM) concept for multiple-input-multiple-output (MIMO) systems. ...
    • Reliable MAC design for ambient assisted living: moving the coordination to the cloud 

      Kartsakli, Elli; Antonopoulos, Angelos; Lalos, Aristeidis; Tennina, Stefano; Di Renzo, Marco; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2015-01)
      Article
      Accés restringit per política de l'editorial
      Ambient Assisted Living (AAL) technologies constitute a new paradigm that promises quality of life enhancements in chronic-care patients and elderly people. From a communication perspective, they involve heterogeneous ...
    • RLNC-aided cooperative compressed sensing for energy efficient vital signal telemonitoring 

      Lalos, Aristeidis; Antonopoulos, Angelos; Kartsakli, Elli; Di Renzo, Marco; Tennina, Stefano; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (2015-07-01)
      Article
      Accés obert
      Wireless body area networks (WBANs) are composed of sensors that either monitor and transmit vital signals or act as relays that forward the received data to a body node coordinator (BNC). In this paper, we introduce an ...
    • Towards the performance and energy efficiency comparison of spatial modulation with conventional single-antenna transmission over generalized fading channels 

      Ntontin, Konstantinos; Di Renzo, Marco; Pérez Neira, Ana Isabel; Verikoukis, Christos (2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, we present a performance and energy efficiency comparison of the recently devised single RF Multiple- Input-Multiple-Output (MIMO) concept of Spatial Modulation (SM) with the conventional single-antenna ...
    • WSN4QoL: a WSN-oriented healthcare system architecture 

      Tennina, Stefano; Di Renzo, Marco; Kartsakli, Elli; Graziosi, Fabio; Lalos, Aristeidis; Antonopoulos, Angelos; Mekikis, Prodromos Vasileios; Alonso Zárate, Luis Gonzaga (2014-05-06)
      Article
      Accés obert
      People worldwide are getting older and this fact has pushed the need for designing new, more pervasive, and possibly cost effective healthcare systems. In this field, distributed and networked embedded systems, such as ...
