In this paper, we study physical layer security (PLS) of wireless networks in presence of one eavesdropper. Assume that the channel state information (CSI) of the eavesdropper cannot be obtained at the transmitter, such as CSI can be then estimated through the CSI of a torch node. In addition, a practical issue of wireless nodes, i.e., hardware impairment (HI), is considered at the source node of the network. System performances in terms of secrecy outage probability, probability of non-zero secrecy capacity and ergodic secrecy capacity are then investigated over Rayleigh fading channels. In particular, the closed-form expressions of the secrecy outage probability and probability of non-zero secrecy capacity are provided. Analytical results are then validated by Monte-Carlo simulation. Numerical results reveal the effects of the HI and the advantages of the use of the torch node in PLS of wireless communications.
