This paper studies the physical layer security of uplink (UL) transmission in simultaneous wireless information and power transfer (SWIPT) deployed in wireless sensor networks (WSNs). Firstly, we model the random network as Poisson cluster process (PCP) to focus on the case where eavesdroppers hide around certain targets to intercept the confidential information successfully. Then, the communication...
This paper investigates the secrecy outage performance of amplify-and-forward (AF) relaying cooperative cognitive radio networks (CCRNs) over Rayleigh fading channels. Specifically, collaborative distributed beamforming is employed at relays to avoid interfering the primary users. Moreover, passive eavesdropping scenario is considered in this work, while the channel state information of the eavesdropping...
This work investigates the secure transmission in the wireless information and power transfer system where a source node communicates with a wireless-powered full-duplex destination node in the presence of a passive eavesdropper. In particular, we propose such a two-phase time-sharing (TS) secure communication protocol: in the first phase, energy harvesting is conducted from the source node to the...
