Binary-Partition-Assisted MAC-Layer Broadcast for Emergency Message Dissemination in VANETs

Impact of propagation environments on emergency message dissemination in VANETs

“…Thus, collision rate is reduced and the contention duration is stabilized. It is also shown that BPAB demonstrates a good performance in terms of the average dissemination speed compared to the other protocols, such as UMB and SB [5]. However, the further study may be needed to confirm that the binary partitioning is the optimal solution among any n-partitioning mechanisms.…”

“…Binary-Partition-Assisted Broadcast protocol (BP AB) BPAB [5] aims to reduce and makes communication delay as constant as possible regardless the size of network. BPAB achieves a good message progress speed by selecting the furthest forwarder.…”

“…In particular, researchers in both automotive industry and academic institutions [1][2][3][4][5][6][7][8][9] have been working to deploy emergency message (EM) dissemination applications over Vehicular Ad hoc Networks (VANETs).…”

“…However, the performance of the real implementation may be different from the results of simulations, as most of the existing simulators consider very basic and simple propagation models [2][3][4][5][6][7].…”

“…However, the realistic propagation models were not appropriately taken into account by such papers [2][3][4][5][6]. These simple simulations may lead to impractical and unreliable performance evaluation.…”
