“…Ai et al [31] analyzed the average secrecy capacity for V2V communications under a double Rayleigh fading channels and considered the impacts of fading, path loss, and eavesdropper location. Wang et al [32] established an analysis framework to explore the optimal secrecy throughput of a V2V network based on a maximum SIN association scheme. Wang et al further investigated the potential of AN techniques in safeguarding security for C-V2X networks in [33].…”

“…However, AN may be rather harmful to other nearby legitimate nodes in wireless networks because jamming signals raise interference. In this regard, through applying stochastic geometry theory, network-wide secrecy performances have been analytically quantified in various scenarios, e.g., the millimeter wave ad hoc network [ 38 ], three dimensional IoT networks [ 39 ], covert communication in D2D networks [ 40 ], vehicular networks [ 41 ], and uncoordinated random jamming in wireless sensor networks [ 42 ]. Further, several studies investigated the effect of an FD jamming approach, where FD nodes receive informative data from their transmitter while simultaneously sending AN for confounding Eves [ 19 , 20 ], in terms of strengthening network-wide secrecy performances in wireless distributed networks [ 21 , 22 ], under stochastic geometry frameworks.…”

With the increasing demand for data exchange between nearby devices in proximity-based services, enhancing the security of wireless mutual broadcast (WMB) networks is crucial. However, WMB networks are inherently vulnerable to eavesdropping due to the open broadcast nature of their communication. This paper investigates the improvement of secrecy performance in random-access-based WMB (RA-WMB) networks by integrating physical layer security (PLS) techniques with hybrid duplex (HBD) operations under a stochastic geometry framework. The HBD method balances half-duplex (HD) receiving and full-duplex (FD) transceiving, utilizing self-interference cancellation (SIC) to enhance PLS performance. Key operational parameters, including transmission probability (TxPr), friendly jammer density, and conditions for FD operation, are designed to maximize secrecy performance. The analytical and numerical results demonstrate significant improvements in PLS performance, with SIC playing a critical role, particularly in scenarios with dense legitimate nodes, and with TxPr adjusted to balance HD receiving and FD transceiving based on SIC imperfections. The proposed design principles provide a comprehensive framework for enhancing the security of WMB networks, addressing the complex interplay of interference and SIC in various network configurations.
