    • On the impact of correlated sampling processes in WSNs with energy-neutral operation 

      Matamoros, Javier; Calvo-Fullana, Miguel; Antón-Haro, Carles (Institute of Electrical and Electronic Engineers, 2015-06-12)
      Comunicació de congrés
      Accés obert
      In this paper, we consider a communication scenario where multiple EH sensor nodes collect correlated measurements of an underlying random field. The nodes operate in an energy-neutral manner (i.e. energy is used as soon ...
