| ABSTRACT |
|
We present network requirements for an overtaking assistant service using wireless access in vehicular environment (WAVE). Currently, DNPW has been proposed as a representative overtaking assistant service with vehicle-tovehicle (V2V) communication. In order to analyze its network performance, we construct a maneuver model for an overtaking system. According to this model, we configured a scenario for network simulation based on the 802.11p WAVE standard. The results confirm that a radio range for overtaking needs only a single hop without routing methods. Moreover, we propose an additional safe distance for the communication delay generated by an increase in the numbers of neighboring vehicles. And for high priority activity of safety services, we present a proper access category (AC) of enhanced distributed channel access (EDCA). These analysis results should be tested considered in real safety service systems that use V2V communication. |
