초록
최근 무선 통신의 발달과 무선 접속 기기의 등장으로 인하여 언제, 어디서든 인터넷을 접속하여 다양한 응용 프로그램을 사용할 수 있게 되었다. 특히, 차량 네트워크의 발달로 이동 중인 차량에서도 인터넷 접속이 가능하게 되었다. 또한, 차량 네트워크와 관련된 다양한 연구들이 활발히 진행되고 있다. 본 논문에서는 실제로 쓰이는 다양한 차량 네트워크의 구조를 살펴보고, 각 구조에서 차량 내에서의 Wi-Fi와 외부의 네트워크를 종합적으로 고려하여 성능 측정을 하였다. 성능 측정 결과를 통해서 현재 사용되고 있는 차량 네트워크의 유용성을 판단하였다.
Abstract
Due to advances in wireless communications and portable terminals, any-time, any-where, and any-device Internet access is possible. In particular, Internet access in moving vehicles is an emerging and challenging issue. Even though a variety studies have been conduced for vehicular networks, little attention is paid to vehicular Wi-Fi networks where a Wi-Fi access point (AP) is installed at the vehicle and the AP is connected to an external base station (BS). In this paper, we conduct a measurement study on the uplink and downlink throughput for Internet access in vehicular Wi-Fi networks. We consider diverse network environments: high-speed train, car, and subway. Measurement results demonstrate that current Internet access in vehicular Wi-Fi networks are not satisfactory for interactive multimedia applications. Therefore, in-depth study on resource management in vehicular Wi-Fi networks is strongly required.
