초록

현재 표준 차량 통신 프로토콜인 IEEE 802.11p는 차량 간 한 홉 전송을 수행하기 때문에 차량 환경에서 효율적인 정보 전달을 수행하는데 한계가 있다. 본 논문은 차량 환경에서 효율적인 정보 전달을 위해 무선 근거리 통신 중 하나인 LTE-D2D 기술을 사용한 차량 네트워크를 제안한다. 이때 전송 메시지 형태는 IP 패킷 옵션을 지닌 이름 기반 정보 메시지를 사용하고 일반 차량 노드는 요청하는 메시지를 중간 매개 노드인 대형 차량 노드로 전송하여 정보를 전송 받는다. 성능 분석을 통해 셀룰러 네트워크와 제안된 LTE-D2D 차량 네트워크에서의 패킷전달 시간에 따른 데이터 처리율을 비교하였다.

Current IEEE 802.11p which is suggested for vehicle to vehicle communication supports one hop communication. Thus, it has a limitation to carry out efficient data dissemination. In this thesis, we suggest LTE-D2D based vehicle network to provide efficient data dissemination in the vehicle environment. In this network architecture, we use name based message with IP packet options and we put the intermediate vehicle node called 'super vehicle node' and each normal vehicle node in the cell requests data to the super vehicle node. The super vehicle node responses data to the normal vehicle node. Performance analysis is based mathematical modeling. We compare LTE cellular network to LTE-D2D based vehicle network about throughput according to packet delivery time.
