  Abstract: In this paper, we investigate the impact of saturation nonlinear energy harvesting (EH)
  and activation threshold on the multiuser wireless powered sensor networks (WPSNs) from the
  physical layer security (PLS) perspective. In particular, for improving the secrecy performance,
  the generalized multi
