%X Traffic safety applications using vehicle-to-vehicle (V2V) communication is an emerging and promising area within theITS environment. Many of these applications require real-time communication with high reliability.To meet areal-time deadline, timely and predictable access to thechannel is paramount.The medium access method used in 802.11p,CSMA with collision avoidance, does not guarantee channelaccess before a finite deadline.The well-known property of CSMA is undesirable for critical communications scenarios. The simulation results reveal that a specific vehicle is forced to drop over 80%of its packets because no channel access was possible before the next message was generated. To overcome this problem, we propose to use STDMA for real -time data traffic between vehicles. The real-time properties of STDMA are investigated by means of the highway road simulation scenario, with promising results.
