The quality of message transmission in a wireless automotive network is considered as a key component of the reliability of intelligent transport systems (ITS) with an emphasis on communication technology between VANET automotive network objects. Analysis of the results of previous studies of the quality of communication according to the IEEE 802.11p standard revealed its inability to support the maintenance of modern automotive applications. The peculiarities of data transmission in the network according to the IEEE 802.11bd standard, which is recommended in the latest report of the European CCAM platform [1] for the exchange of "Vehicle-Vehicle" and "Vehicle-Іnfrastructure" messages, have been studied. Analytical modeling of network service quality according to the IEEE 802.11bd standard using Markov chains was carried out. The simulation results confirmed the hypothesis that the IEEE 802.11bd message transmission protocol provides high quality communication in the VANET network. Keywords: intelligent transport system, car network, analytical model, IEEE 802.11 bd, quality, dedicated communication, network maintenance.Downloads
