Modelling the packet delivery of V2V messages based on the macroscopic traffic parameters

In this paper, we present an analytical model for estimating the Packet Delivery Ratio (PDR) in vehicular communication using IEEE 802. 11p protocol for a highway scenario based on the macroscopic traffic parameters. We also consider the effects of Decentralised Congestion Control (DCC) based on Transmit Rate in improving the PDR. The model is validated using a simulation environment based on Artery and its estimation of the PDR is found to be within 1 % deviation of the PDR calculated from the simulation environment. We also show a use case of our model in identifying the correct DCC parameters at which the DCC will be activated based on the macroscopic traffic parameters.
