Abstract
In this paper, we investigate inter-vehicle networks offering an application of safety driving support. For appropriately evaluating the efficiency of inter-vehicle communication systems to support such an application, it is of paramount importance to make extensive evaluations under realistic accident model. In this paper, assuming realistic intersection collisions scenarios, we provide simulation results of an inter-vehicle network based on an experimental guide-line defined for inter- vehicle communications system in Japan. Besides the guideline system, we also present our newly developed inter-vehicle communication system based on code division multiple access (CDMA) scheme. Our numerical results show that the proposed CDMA based system can effectively combat hidden-terminal problem as well as high level of congestion around an intersection, and is the only system to satisfy the requirements set by the application for safety driving support.
