Performance Evaluation according to RSU Range in Vehicle-to-Vehicle Communications

Abstract

Recently, wireless communication technology and Intelligent Transportation System (ITS) technology in vehicles have been developed. Therefore, it becomes a vehicle and the necessary communication skills for improving safety and traffic flow for drivers has been the study of the Vehicular Ad-hoc Network (VANET) based vehicle communication technology progress. This study aims to implement a simulation of a VANET. It is a special kind of Mobile Ad-hoc Network (MANET) adapted to the communication between vehicles. It moves at high speed and is further classified into vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication methods. To develop a VANET-based vehicle wireless communication technology, it is necessary to establish a test environment and synchronize vehicle mobility in various road scenarios. However, the equipment is expensive for the built experiment environment, and the road traffic situation is difficult to predict. In this study, the simulation of VANET is intended to be tested in an urban environment, and the result can be used also to develop the Media Access Control (MAC) protocols. This paper proposes a scheme for experiments in a similar environment to actual urban traffic and analyzes the performance by dividing it into V2I and V2V nodes according to the RoadSide Unit (RSU) coverage.
