Vehicular ad hoc networks (VANETs) are an important part of the next generation of intelligent transportation. For multimedia information transmissions, VANETs require high speed and a low-delay link between the vehicles. This paper focuses on a connectivity analysis of VANET high-speed and low-delay connections under different traffic densities and adverse weather conditions. In this paper, a channel measurement at 5.9 GHz under two kinds of traffic densities is first carried out. Then, the measured data for the path loss are used in the VANET model for the connectivity probability. Finally, we consider the influence of adverse weather conditions on the wireless signal and simulate the influence on the high-speed and low-delay data connectivity of VANETs. The results show that adverse weather will have a certain impact on vehicle-to-vehicle (V2V) communication.
