  • Energy and Spectrum Efficient Parameter Estimation in Wireless Body Sensor Networks 

    Argyriou, A. (2015)
    In this letter we consider the problem of linear distributed estimation (DES) of a random parameter in a wireless body sensor network (BSN). We propose a novel architecture, and an associated optimization model, for DES ...
  • Energy aware buffer aided cooperative relay selection 

    Hadef, M.; Apostolaras, A.; O'Reillys, J.; Mourad, A.; Mouhouche, B.; Koutsopoulos, I.; Korakis, T.; Tassiulas, L. (2014)
    In this paper we evaluate an energy-aware relay selection mechanism which exploits channel state information and the availability of buffers at relays to perform flexible relaying based on a backpressure-driven optimization ...
