Design and implementation of a VANET application complying with WAVE protocol

The Wireless Access in Vehicular Environment (WAVE) protocol is capable of providing safety, seamless and effective communication for the Vehicular Ad-hoc Network (VANET). Although some companies have launched the products of PHY and MAC layer modules, there is no mature system-level WAVE product. Obviously, a well-performed application layer program design complying with the WAVE protocol is essential to the low-latency and low-overhead VANET. In this paper, we present the design and its implementation of such a program which includes the basic Intelligent Transportation System (ITS) functionality, especially the two safety sub-applications: Emergency Electronic Brake Lights and Intersection Collision Warning. In order to run the program in a traffic scenario, we also develop a traffic simulator. The conducted tests show that the developed application provides efficient communication and performs well.
