 This paper mainly studies on the performance of vehicle ad hoc network based on Rayleigh decay channel. Considering
the highway scenario, this paper analyzes several network performance indicators of vehicle communication with roadside units,
such as interrupt probability, packet error probability, average packet loss probability, and so on. Numerical simulation is performed
to discuss the effects of different parameters on these network performance indicators, including the size of the competition window,
the size of the packet, the number of vehicles, the speed of the vehicle, and the arrival rate of the packet. Simulation results show
that the proposed network performance analysis model is valid. This model can be used to analyze the influence of various parame-
ters on the performance of the off-road communication network in highway scenarios, and provide reference for designing a reason-
able roadside unit deployment scheme.
