Vehicle-to-vehicle (peer-to-peer) communication is expected to play an important role in ITS (Intelligent Transport Systems). This paper proposes an adaptive media switching method for future vehicle-to-vehicle communication. Our method adopts an approach to select the most suitable radio communication media from several possible types based on the vehicle locations, available media and communication quality. Before the network configuration of inter-vehicle and roadside-vehicle communication changes, the vehicle detects it and then initiates the media reselection. During such media switching, our proposed HTTP-based session layer mobility avoids any interruption of communication. We conducted field tests using several experimental vehicles. The results verify that our proposed method is effective in selecting the most suitable media, and disconnection of communication during the media switching is also avoided.
