BSM Emulator - advanced vehicle safety application testbed

The emerging IEEE 1609/802.11p network protocol suite [1][2][3][4][5][6][7] enables a variety of vehicular applications [8]. For example, applications based on SAE J2735 Basic Safety Messages (BSMs) [9] have been developed to avoid vehicle collisions and enhance driving safety. Evaluation of applications to be deployed is usually conducted with field trials, which are costly and labor intensive. In this paper, we develop and implement a network emulation platform (called the BSM Emulator) for the new IEEE 802.11p/1609 network. The BSM Emulator can generate SAE J2735 BSMs with different MAC addresses, emulating the existence and the behaviors of multiple OBUs and vehicles. By using this tool, one IEEE 802.11p/1609 device can imitate the BSM broadcast behaviors of multiple vehicles around an intersection, greatly facilitating field trials of vehicular networks/applications and reducing the cost of conducting field trials. To the best of the authors´ knowledge, this paper is the first work that develops and implements an integrated environment for the emulation of IEEE 802.11p/1609 network and SAE J2735 related vehicular applications.
