摘要: In this paper, we propose to apply Contention-Based Forwarding (CBF) Vehicular Ad Hoc Networks (VANETs). CBF is a greedy position-based forwarding algorithm that does not require proactive transmission of beacon messages. performance analyzed using realistic movement patterns vehicles on highway. We show by means simulation as well traditional routing (PBR) achieve delivery rate almost 100 given connectivity exists. However, has much lower overhead than PBR since can high ratios only implicitly trial-and-error next-hop selection strategy. With CBF, better total throughput be achieved. further discuss several optimizations for its use in VANETs, particular new position-encoding scheme naturally allows communication paradigms such `street geocast` and flooding`. The discussions viewed concept convergence intelligent flooding, geocast, multi-hop the area inter-vehicle communication.
