ETSI-ITS-G5 is the current vehicle-to-vehicle communication technology in Europe, which will be standardized by ETSI TC ITS. It is based on IEEE 802.11p and therefore uses a CSMA/CA scheme for Media Access Control (MAC). The performance of CAM based safety applications has been analyzed, using the ETSI ITS-G5 MAC technology in a challenging scenario with respect to MAC issues: A suitable freeway segment with 6 lanes in each direction has been chosen. The freeway scenario has been thoroughly modelled and implemented in the well known ns-3 simulation environment. Based on this model, the performance of CAM based safety applications under MAC challenging conditions will be shown. Therefore a set of simulation results will be provided, resting upon a particular performance metric which incorporates the key requirements of safety applications. Finally, two concrete example scenarios will be analyzed to make a point how reliable CAM based safety applications are in high dense traffic scenarios.
