Abstract

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). In this paper we analyze the performance of ETSI ITS-G5
\nMAC in a challenging scenario with respect to MAC issues: A suitable freeway segment with 6 lanes in each direction. The freeway scenario is thoroughly modeled and implemented in the well known ns-3 simulation environment. Based on this model, the paper shows the performance of ETSI ITS-G5 MAC under MAC challenging conditions. We provide a particular performance metric which incorporates the key requirements of
\nsafety applications.
