Abstract
In order to appropriately evaluate performance of inter-vehicle communication systems which support safety driving, it is important to perform evaluation under realistic accident scenarios with suitable application requirements. In this paper, assuming realistic intersection collision scenarios, we perform simulation evaluation of CSMA based inter-vehicle networks based on experimental guide-line defined by ITS Info-communications Forums. We compare performance of CSMA based systems with that of our proposed MM-SA (Multi-Carrier Multi-Code Spread Aloha) system employing CDMA (Code Division Multiple Access) scheme. The simulation results show that MM-SA has superior performance to CSMA based systems thanks to high robustness to high level of interference as well as to hidden terminal problem.
