Simulation and Performance Evaluation of Vehicle-to-Vehicle (V2V) Propagation Model in Urban Environment

Abstract

Vehicle-to-Vehicle (V2V) communications offer support to several applications that can make the modern day travel safer, more efficient and enjoyable. However, reliable and efficient V2V application development requires better understanding and knowledge of the surrounding environment in which the vehicles operate them. The urban environment consists of open, downtown, suburban, wider and narrower spaces which vary significantly in their radio channel characteristics. Therefore studies on V2V propagation channels that take in to account random and time-varying of different environments are highly sought-after. In this paper a detailed overview of V2V propagation modeling techniques is provided. Using a case study for the city of Doha, Qatar we explained the metropolitan-area wide characterization of received signal strength. Finally, a comprehensive simulation-based evaluation is presented to measure the impact of geometry-based propagation model on V2V performance in an urban environment using the publicly available simulator. The output from the propagation model simulations is used to analyze V2V communication in terms of several communications and networking performance metrics such received signal strength, packet delivery ratio, and reliable communication range for the given data rate settings.
