Secrecy outage performance for wireless-powered relaying systems with nonlinear energy harvesters
We consider a cooperative system consisting of a source node
a destination node
N
(
N
>
1) wirelesspowered relays
and an eavesdropper. Each relay is assumed to be with a nonlinear energy harvester
in which there exists a saturation threshold
limiting the level of the harvested power. For decode-and-forward and power splitting protocols
the Kth best relay is selected to assist the source-relay-destination transmission. An analytical expression for the secrecy outage probability is derived
and also verified by simulation.
