“…Furthermore, we also assume that all links experience independent and identically distributed quasistatic Nakagami-m fading. In this work, we assume that relay selection process has been conducted before data transmission (The details about the PRS process can be referred to [9]- [11]). Then, under conditional DF scheme, the information transmission process can be divided into two phases; 1) S sends the information to R and D;…”

“…In [8]- [9], the authors proposed a partial relay selection (PRS) scheme for dual-hop fixed-gain relay systems where the optimal source-relay link (OSRL) was employed in the first-hop transmission. Under optimal sourcerelay-destination link (OSRDL) scheme, the best source-relaydestination link was selected as the data transmission link [10]- [11]. However, none of these works has considered EH in multiple-relay systems.…”

Abstract-This paper considers a dual-hop wireless powered cooperative system with multiple relays, which consists of a source (S), a destination (D) and multiple relay candidates. These relay candidates can harvest energy from the interference signals to transfer the decoded data to D. Two classic relay selection schemes, optimal source-relay link and optimal source-relaydestination link schemes, are considered to choose a best relay to aid the transmission between S and D under conditional decodeand-forward scheme. The closed-form expressions of the outage probability for the two considered relay selection schemes have been derived and verified over independent Nakagami-m fading channels.

Summary This paper evaluates the secrecy performance for the amplify‐and‐forward (AF) protocol with partial relay selection (PRS) schemes in the scenario of multiple independent but not necessarily identically distributed eavesdroppers. The secrecy performances of the first‐hop and second‐hop PRS schemes are revisited. Given the secrecy data rate, an efficient PRS scheme is presented, which selects the relay based on the instantaneous channel state information (CSI) of either the first or second hop according to the statistical CSI of two hops. The proposed PRS scheme provides the trade‐off between the two‐hop and one‐hop PRS criteria. Results show that the secrecy outage probability (SOP) performance of the proposed scheme is close to that of the conventional opportunistic relaying in the medium main‐to‐eavesdropper ratio (MER) regions. As for the intercept probability, the second‐hop scheme achieves the highest diversity order among PRS schemes and its performance depends on the overall eavesdroppers' behavior not on individual effects of the specific relay. The proposed criterion also outperforms the first‐hop PRS scheme. Simulation results finally substantiate the accuracy of the theoretical analysis.

In this paper, the selective cooperation with untrusted relays is studied for wireless multipair two‐way relay networks. We first investigate the feasibility of secure transmission in the presence of cooperative but untrusted relays and then formulate a general optimization problem of secrecy sum‐rate maximization under the constraints of relay selection. By decomposing the original problem into solvable subproblems, we develop a low‐complexity greedy algorithm for selective cooperation, in which the untrusted relays are selected as cooperators or the potential eavesdroppers according to the overall contributions to the secrecy sum rate. Simulation results reveal that the proposed greedy algorithm for selective cooperation with untrusted relays achieves performance gain both in instantaneous and average secrecy sum rate and that the algorithm can converge quickly with the iterations.
