초록

차량통신은 통신시스템과 차량산업을 융합하여 ITS(Intelligent Transport Systems) 분야에서 다양한 서비스 제공을 위해 고려되어 왔다. 일반적으로 차량통신은 WAVE(Wireless Access in Vehicular Environments)라고 알려져 있는 IEEE 802.11p/1609표준을 채택하여 vehicle-to-vehicle(V2V)와 vehicle-to-infra(V2I) 통신에 이용된다. WAVE 시스템은 OFDM(Orthogonal Frequency Division Multiplexing) 신호를 5.835~5.925 GHz대의 주파수를 사용하여 전송하는 시스템이다. 본 논문에서는 IEEE 802.11p 표준에 따라 구현한 WAVE 시스템의 MAC(Media Access Control)단에서 채널 모니터링을 32 비트 처리한 다음 데이터를 수신하여 성능을 평가하였다. 실제 고속도로에서 OBU(On Board Unit)로 구성된 테스트베드를 구축하고, OBU간에 WSM(WAVE Short Message)을 무선으로 송수신한 다음, 프레임 당 채널 점유 시간과 처리량을 산출하였다.

Vehicular communications have been receiving much attention in intelligent transport systems(ITS) by combining communication technology with automobile industries. In general, vehicular communication can be used for vehicle-to-vehicle(V2V) and vehicle-to-infrastructure( V2I) communication by adopting IEEE802.11p/1609 standard which is commonly known as wireless access in vehicular environment(WAVE). WAVE system transmits signal in 5.835~5.925 GHz frequency band with orthogonal frequency division multiplexing(OFDM) signaling. In this paper, after 32 bit processed the channel monitoring in MAC(Media Access Control) layer of WAVE system implemented according to IEEE 802.11p standard, data were received and we evaluated the performance, we built the test bed consisting of OBU(On Board Unit) in the real expressway. We transmitted WSM(WAVE Short Message) and received WSM between OBU wirelessly. And then, we calculated channel occupancy time per one frame and throughput, and evaluated the performance.
