ITS services are quickly evolving due to the convergence of ICT technologies. WAVE technology based on IEEE802.11p specification has been introduced for the high speed vehicle communication and applied into the transportation system for driving safety and convenience. Recently, WAVE technology as a inter vehicle communication is used for cooperative driving application. In this paper, the implemented inter vehicle communication system is introduced and suggested as a solution for V2X communication. The performance of the implemented inter vehicle communication system is tested and analyzed under various conditions.
