초록
커넥티드 카에서 발생하는 실시간 데이터 처리를 위한 엣지–커넥티드 카 환경에서 웹소켓 통신 연구가 활발히 진행되고 있다. 그러나 웹소켓은 연결 유지, 고정된 연결의 특성으로 대용량 데이터 처리를 위한 분산 엣지 환경을 구성하는데, 구조적 한계가 있다. 기존 연구는 세션 공유, 아파치 카프카 통신을 활용했으나, 이는 추가 리소스와 종속성, 확장성 문제가 존재한다. 본 연구는 실시간성, 확장성, 낮은 리소스를 보장하는 새로운 웹소켓 기반 데이터 통신 기법을 제안하며. 이를 Digital Twin 모델에 적용하였고 차량 충돌 이벤트 처리를 통해 제안된 기법의 효율성을 검증했다.
Abstract
Research on WebSocket communication in edge-connected car environments is ongoing. WebSockets have structural limits for large data handling due to persistent and fixed connections. Previous approaches using session sharing and Apache Kafka faced scalability and resource dependency issues. This study proposes a new WebSocket-based technique that ensures real-time, scalable, and resource-efficient data communication. It has been applied to the Digital Twin model, proving its effectiveness through vehicle collision event handling.
