摘要

As one of the most promising communication technologies for vehicular networks,LTE-V has the advantages of wide coverage and a high transmission rate.3GPP released the technical specification of LTE-V in March 2017,launching a spate of related research and industrialization.In this paper,we propose a communication model based on Markov process to evaluate the reliability of LTE-V.We derived the Packet Delivery Rate (PDR) of LTE-V based on the model.Moreover,we use Poisson process to model the distribution of vehicles on a highway,then combine the communication model with the vehicles' distribution to derive the PDR under this scenario.To verify the correctness of the proposed model,we established a simulation program on the MATLAB platform.By comparing the simulation results and the mathematical results,we found that simulation results are a very good fit for the model.
