Secrecy outage probability of a two-way cooperative network with an energy harvesting untrusted AF relay

Secrecy outage analysis of energy harvesting two‐way relaying networks with friendly jammer

“…The authors in [19,20] considered an EH TWR network where two sources exchange their information through a half-duplex (HD) relay. In the system model considered in [19,20], the relay is also a potential eavesdropper [The relay which plays both roles as the pure relay and the eavesdropper is called the untrusted relay.]. Both secrecy rate and secure energy efficiency were optimised in [19] while the secrecy outage probability was analysed in [20].…”

Both secrecy rate and secure energy efficiency were optimised in [19] while the secrecy outage probability was analysed in [20]. The relay output power is minimised in [8] and the secrecy sum rate is maximised in [21] for an EH TWR network where two sources exchange their information through a FD relay.…”

“…Extending [21] to the case of multiple eavesdroppers, Lee et al [25] maximised the minimum guaranteed secrecy capacity. All these works in [8,[19][20][21][22][23][24][25] only investigated one relay. In the case of multiple relays in EH TWR networks, Khandaker et al [7] proposed a relay selection scheme to maximise the secrecy sum rate for EH TWR networks.…”

“…The above publications [7,8,[19][20][21][22][23][24][25] exposed that only [20,23] analysed the security performance of EH TWR networks. Motivated by this fact, the current paper analyses the secrecy outage probabilities of EH TWR networks where two sources exchange their information through an EH relay which operates in the amplify-and-forward (AF) manner and the exchanged information is wire-tapped by an eavesdropper but assisted by a friendly jammer.…”

“…Motivated by this fact, the current paper analyses the secrecy outage probabilities of EH TWR networks where two sources exchange their information through an EH relay which operates in the amplify-and-forward (AF) manner and the exchanged information is wire-tapped by an eavesdropper but assisted by a friendly jammer. Therefore, our work exploits the trusted relay instead of the untrusted relay in [20,23]. Furthermore, although our work and [20] analyse the same security performance metric (i.e.…”
