Data Transmission Between Dedicated Short Range Communication and WiMAX for Efficient Vehicular Communication

摘要

In recent years, lot of research activities undergone on vehicular communication. An intelligent transportation system (ITS) is a technology particularly used for transportation that uses moving cars as nodes in a network to create a mobile network. This technology offers an extensive range of applications including safety and non safety applications such as traffic management, road safety and infotainments. Vehicles are dynamically clustered according to different metrics such as direction of vehicles' movement, WiMAX Received Signal Strength, and inter-vehicular distance, respectively. In this work, Authors focus on the design of hybrid communication system for vehicular communication. The Dedicated Short Range Communication (DSRC) and WiMAX can be converged for the same. Authors have designed the physical layer to bridge between DSRC and WiMAX which involves all the processing performed on peak data rates of more than the vehicular communication standards. Authors successfully simulated data transmission of this system in MATLAB. By using OFDM physical layer parameters we can combine IEEE 802.11p standards and WiMAX to achieve such a performance in ITS.
