A Simulation-based Study on the Environment-Specific Propagation Model for Vehicular Communications

Abstract

Vehicle-to-Vehicle (V2V) communication environment vary significantly in radio channel characteristics. Therefore, simulation-based studies on V2V propagation models that consider random and time-varying characteristics of surrounding environment are highly sought-after. This paper includes a detailed overview of the existing V2V channel modeling techniques. Followed by the details on what information is required to perform large-scale simulations of the environment-specific vehicular channel model. Next, the authors propose a simulation model which combines data from several sources such as 2.5D building geometry data and vehicular mobility traces to create a realistic simulation environment. Finally, the given reference scenario has been assessed regarding several performance metrics and parameter settings using a publicly available geometry-based V2V propagation model. The simulation results show that building and vehicle obstructions significantly attenuate the signal thus resulting in lower received signal strength, lower packet delivery ratio, and shorter effective transmission range.
