(English Abstract)
We conduct the network performance analysis for infrastructure-to-vehicle communications with the empirical trajectory data from NGSIM (Next Generation Simulation), and the default parameters from IEEE 802.11p standard are applied for EDCA (Enhanced Distributed Channel Access) setup. Different contending node ratios for ACs (Access Categories) are considered, and we analyze the network performance in terms of the average network system throughput and the expected node throughput at the access categories. We use multiple data rates for 10MHz channel, and simulation results include the network performance with modified parameter values. Simulation results show that the parameter should be controlled based on the number of contending nodes and the setup of CW(Contention Window) of high priority AC is the critical factor with regard to the transmission performance.
