Wireless Peer Discovery in Heterogeneous Half-/Full-Duplex Networks

Secrecy Performance Enhancement Using Self-Interference Cancellation in Wireless Mutual Broadcast Networks for Proximity-Based Services

“…Like any wireless network with performance limited by mutual interference [27], interference in WMB networks similarly impairs system performance. Stochastic geometry facilitates the mathematical tractability of wireless network performances through stochastically modeling the spatial radio interaction among devices [27], and several literatures have quantified and improved network-wide performances of WMB [24,[28][29][30][31][32][33][34][35][36], under stochastic geometry frameworks. The works in [28,29] mathematically quantified the average number of successfully discovered nodes, and they proposed the design principles for improving performance.…”

“…Each legitimate node either receives BMs from other nodes without SIC, or simultaneously transmits its own BM while receiving BMs from other nodes using SIC. The model assumes that all nodes are synchronized for this operation [ 28 , 29 , 33 , 35 ]. In this network, a legitimate node works in either of the following three modes: RxOnly (denoted by ): A node only gathers BMs broadcast by other legitimate nodes and it does not transmit any signal.…”

“…The work in [ 31 ] studied the resource allocation method to mitigate interference through geo-location-based access in V2V WMB networks, and it demonstrated the performance gain through modeling vehicular networks based on stochastic geometry. The study on WMB has been further extended in conjunction with various issues including low power design [ 32 ], full duplex [ 33 , 34 ], and energy harvesting [ 35 ], in terms of network-wide performances. The works in [ 33 , 34 ] demonstrated that SIC significantly affects RA-WMB performance depending on the level of residual self-interference (RSI).…”

The works in [ 33 , 34 ] demonstrated that SIC significantly affects RA-WMB performance depending on the level of residual self-interference (RSI). In particular, the work of [ 34 ] showed that adjusting the proportions of simultaneous transceiving nodes and receiving-only nodes may improve RA-WMB performance compared to a scenario where all nodes are simultaneously transceiving with SIC, especially at high RSI levels.…”
