Abstract
본 논문은 도로에 설치된 인프라 시스템 및 타 자율 주행 차량과 협력하여 주행하는 협력형 무인 자율 주행차량 기술을 위한 멀티케스트 통신 기법을 소개한다. 협력형 자율 주행 차량은 주행 안전성 향상을 위해 인프라시스템 및 주변 차량과 통신한다. 교환되는 정보는 차량 안전과 관련 된 정보이며 다수의 자율 주행 차량에게 정의된 시간 내에 반드시 전송되어야 한다. 그러나 차량 통신 국제 표준인 WAVE는 협력형 자율 주행을 위해 요구되는 멀티케스팅 통신의 높은 전송 성공을 보장하지 않는다. 본 논문에서는 WiVCL이라는 MAC 계층의 고신뢰멀티케스트 기법을 제안한다. IEEE 802.11p 및 BMW와 비교한 결과 WiVCL은 높은 전송 성공률과 예측 가능한전송 지연 시간을 보여줌을 확인할 수 있었다.
