Vehicular ad hoc network (VANET) is a promising technology for intelligent transportation systems, where dedicated short range communication (DSRC) is usually used for inter-vehicle communications. When the vehicle density is high, the randomly access feature of the carrier sense multiple access with collision avoidance (CSMA/CA) mechanism in DSRC will lead to the increased channel contention delay. Therefore, visible light communication (VLC) can be introduced to form a heterogeneous VLC-DSRC network for delay reduction. Although VLC has no contention delay, one VLC link can only be established between two adjacent vehicles, which might increase the delay caused by multi-hop communications. In this paper, a delay-minimization link selection scheme is proposed to select appropriate links for vehicles according to actual situations and minimize average delay. Simulation results demonstrate that the proposed scheme outperforms the considered benchmarks in terms of average transmission delay.
