Preliminary Performance Evaluation of IEEE 802.11p in Blind Corner Scenario

In the future, VANET and IEEE 802.11p will play important role in ITS with many applications that improve the quality of traffic. Road environment is one of factors that influences the performance of the wireless communication. Especially for blind corner, the buildings which obstruct the signal may be a big challenge for the data transmission of safety applications. Thus, the performance analysis of IEEE 802.11p should be done with blind corner scenario. In the present, there are few researches about the evaluation of IEEE 802.11p at blind corner with real experiments. In this paper, we provide the success rate and RSSI of packet transmission with real experiment of IEEE 802.11p standard at the blind corner and suggest the number of packet transmissions that reaches an acceptable success rate. Our findings indicate that the nodes cannot communicate if their distance from blind corner is more than 20 meters. In addition, we also found that within 15 meters from corner, the nodes should send at least 5 packets to ensure successful transmission.
