Abstract

The convergence of the automotive industry and the ICT technology can be broadly divided into the commercial service sector and the Cooperative-ITS (C-ITS) service sector. The C-ITS service sector is using V2X communication technology as a field that aims to provide safer transportation, more green and efficient transportation, and more predictable and productive mobility. The recent convergence of self-driving cars and connected cars requires high data rates, low transmission delays, and low transmission error rates. Interest in comparison of performance between WAVE and C-V2X (LTE-V2X, 5G-V2X) has been amplified and application services by communication technology are being studied. In this paper, we design the application performance evaluation method of Hybrid V2X communication system and confirm that the decrease of packet error rate (PER) performance is caused by the increase of communication distance, not the vehicle speed.

자동차산업과 ICT 기술의 융합 분야는 크게 상용서비스 분야와 Cooperative-ITS (C-ITS) 서비스 분야로 나뉠 수 있다. C-ITS 서비스 분야는 더 안전한 운송, 더 친환경적이고 효율적인 교통, 및 더 예측가능하고 생산적인 이동성을 제공하는 것을 목표로 하는 분야로서 V2X 통신기술이 사용되고 있다. 최근 이슈가 되고 있는 자율주행자동차와 커넥티드 카의 융합을 위해서는 높은 데이터 전송율과 낮은 전송 지연, 그리고, 낮은 전송 오류율을 요구한다. 이를 위하여 최근의 WAVE와 C-V2X (LTE-V2X, 5G-V2X) 성능 비교에 관심이 증폭되고 있으며, 통신 기술별 응용서비스들이 연구되고 있다. 본 논문에서 하이브리드 V2X 통신시스템의 응용서비스 성능평가 방법에 대해 설계하였고, 패킷에러율(PER) 성능의 감소는 차량속도가 아닌 통신 거리의 증가에 의해 발생하는 것으로 보이는 결과 등을 확인하였다.
