“…For instance, to obtain 10 −2 IP, the required outage values for M = 6 and M = 1 are around 10 −2 and 10 0 , respectively. These observations are consistent with the analytical derivations, which are (21), (27), and the derived asymptotic expressions. Figure 7 presents the security trade-off analysis of the HD-based and FD-based selection strategies in OWR mode.…”

“…Ozduran 26 also proposes alternative relay selection strategies, which are based on the leakage rate (LR), for enhancing the PHY security of a dual hop multiple HD/FD wireless relaying network. The work of Ozduran 27 and its extended version 28 extend another work 26 by considering the more realistic scenario and investigate the channel estimation error and feedback delay effects on the LR-based selection strategies. This paper extends the works of Ozduran [26][27][28] by taking into consideration the one-way information exchange traffic analysis as well as providing AR performance comparisons and optimization.…”

This paper investigates the leakage rate based untrustworthy relay selection strategies, which are based on the untrustworthy relay terminals operate in half-duplex, full-duplex, and hybrid modes. The investigation considers a dual-hop one/two-way half/full-duplex wireless relaying network in the system model. The investigation also considers that a finite number of friendly jammers affect the untrustworthy relay terminals. According to analytical, asymptotic, and Monte Carlo simulation results, the LR-based untrustworthy relay selection strategies achieve cooperative diversity order in high-signal-to-noise ratio.However, friendly jammers and loop interference severely affect the system performance and degrade the achievable diversity order from M to 0 and also cause system coding gain losses. In addition, friendly jammers and loop interference also degrade the system achievable rate performance and cause saturation in high SNRs.Trans Emerging Tel Tech. 2019;30:e3755.wileyonlinelibrary.com/journal/ett

“…Furthermore, the performance of FD-TWR networks with best relay selection in the presence of CEE have been analyzed in the works of Ozduran et al 33 and Ozduran. 34 Apart from CEE, due to the aggressive reuse of frequency channels, the cellular TWR systems will inevitably be subjected to cochannel interference (CCI). It can limit the system performance and hence should be considered while designing the system.…”

This paper considers a full-duplex (FD) cellular multiuser two-way multirelay network, wherein one N a -antenna base station communicates bidirectionally with M single-antenna users via L single-antenna amplify-and-forward relays. A practical scenario where cochannel interference (CCI) and channel estimation error (CEE) present in the network is considered for the investigation.Considering the CEE and interferers at the relays, we formulate the Nth worst relay selection scheme, which consists the best relay selection as a special case.With such relay selection strategy, we derive the tight lower bound (LB) expressions for the overall outage probability, average bit error rate, and ergodic sum rate with CEE and CCI under Rayleigh fading. Furthermore, we deduce the asymptotic expressions for the overall outage probability and average bit error rate at high signal-to-noise ratio. Based on the asymptotic outage expression, we present some practical cases of interest, from which the impacts of CCI, CEE, and residual self-interference (RSI) (imposed on the FD nodes) on system diversity order are presented. It is shown via the numerical results that CEE, CCI, and RSI have detrimental impact on the system performance. Our results also reveal that the impacts of CEE, CCI, and RSI can be alleviated by increasing the number of relays. We also obtain some insights on the self-interference cancelation requirements for the FD mode. The numerical and simulation results verify our theoretical analysis.Trans Emerging Tel Tech. 2019;30:e3672.wileyonlinelibrary.com/journal/ett
