Analysis of V2V Communication Performance on Roads and Tunnels Surrounded by Mountains

초록

In this paper, communication performance analysis is conducted for driving scenario using IEEE 802.11p wireless access in vehicular environments (WAVE), a vehicle communication standard. Since vehicle communication is linked to advanced driver assistance systems such as safety and autonomous driving, it is very important to maintain stable communication performance. However, in the vehicle communication environment, it is difficult to ensure a stable performance because the communication terminal moves at high speed and there are various communication interference factors such as changes in the surrounding environment. Therefore, in this paper, scenarios are set for actual vehicle communication environments and the vehicle communication performance is analyzed for each situation based on actual measurement experiments. In the actual measurement experiment, the basic safety message (BSM) of the vehicle is transmitted and received in real-time using two vehicles with two WAVE devices. The received signal strength of the signal is analyzed while exchanging BSM messages. In this experiment, various scenarios are set up and the signal strength for each scenario is analyzed. This paper conducted a performance comparison using the received signal power of messages transmitted and received by driving conditions in the road environment by experimenting with vehicle-to-vehicle communication.
