Performance study of IEEE 802.11p in blind corner scenario

Abstract

In present, IEEE 802.11p is a standard for vehicle communication which can enhance quality of road transportation. The communication in non-line-of-sight is an important scenario that has to be inspected deeply. Because in non-line-of-sight or blind corner scenario, the signals may be obstructed. This reason would lead to communication loss, and be a big challenge for building safety applications. In this paper, we conduct real experiments at different types of blind corners and propose success rate of transmitted packets and RSSI of the received packets. Moreover, we suggest number of packets that have to be sent to ensure that at least one packet is delivered successfully. Our results show that the communication range in blind corner is less than 60 m from the corner, and for the worst case, the communication range is only 20 m from the corner. Our research is useful in daily life and can be contributed to safety applications and protocols implementation, roads and buildings construction, and network simulations.
