Abstract EN
In vehicular ad hoc networks (VANETs), the medium access control (MAC) protocol is of great importance to provide time-critical safety applications.
Contemporary multihop broadcast protocols in VANETs usually choose the farthest node in broadcast range as the forwarder to reduce the number of forwarding hops.
However, in this paper, we demonstrate that the farthest forwarder may experience large contention delay in case of high vehicle density.
We propose an IEEE 802.11-based multihop broadcast protocol VDF to address the issue of emergency message dissemination.
To achieve the tradeoff between contention delay and forwarding hops, VDF adaptably chooses the forwarder according to the vehicle density.
Simulation results show that, due to its ability to decrease the transmission collisions, the proposed protocol can provide significantly lower broadcast delay.
