  • Dedicated Short-Range Communication은 단거리 무선 고속 패킷 통신 기능을 제공하며, 신뢰성, 안전한 데이터 전송 및 낮은 대기 시간으로 인해 Road Safety Application에서 널리 사용되고 있다. 본 논문에서는 SDN의 분산 컨트롤러를 이용하여 DSRC 통신을 제어하는 방식을 제안하였다. 제안한 기법을 실용화한다면 차량을 기반으로 한 실시간 교통 정보 수집이 보다 효과적으로 이루어질 것으로 기대된다.

  • In this paper, we investigated performance for 5.8GHz dedicated short range communication system using OFDM which will be applied to Intelligent transportation system services. The maximum speed of a vehicle in DSRC channel is very fast as 180km/h, so a service time is very short to serve a various traffic information if hand-off is not occurred. Therefore higher bit rate is required to proved advanced and intelligent service to the drivers of various vehicle and the data transmission rate of the next generation DSRC system if being promoted over 10Mbps. The signals received in Racian channel have been simulated using the computer simulator. For performance improvement, BCH coding scheme are adopted.

  • This paper treats performance analysis and improvement of DSRC physical layer which is discussed for standardization at the ISO TC-204 WG-15. DSRC is a short range wireless communication for which distance is less than 100m between RSU and O BE, since DSRC requires cheap and simple modulation technique, ASK is being developed as standard modulation system among PSK, FSK and ASK in our country. This paper analyzes the performance of DSRC physical layer system which is at the first stage of development under Rician fading channel, more sepcifically, the validity of the system and the performance limitations are shown. Both equalizer and antenna diversity techniques are simulated to improve the ASK system performance.

  • DSRC((Dedicated Short Range Communication) is dedicated short range communication for wireless communications between RSE(Road Side Equipment) and OBE(On-Board Unit) within vehicle moving high speed. In this paper, we implemented 5.8GHz DSRC modem according to Korea TTA(Telecommunication Technology Association) standard and investigated implementation results and design process for SoC(System on a Chip) embedding ARM CPU which control overall signal and process arithmetic work. The SoC is implemented by 0.11um design technology and 480pins EPBGA package. In the implemented SoC ($Jaguar^{TM}$), 5.8GHz DSRC PHY(Physical Layer) modem and MAC are designed and included. For CPU core ARM926EJ-S is embedded, and LCD controller, smart card controller, ethernet MAC, and memory controller are designed as main function.

  • DSRC system is a communication system that consists of road side equipment and on board equipment to provide services of communication technology for intelligent transportation systems. In this paper, we carry out a short-range dedicated high-speed wireless communications via DSRC system based on board equipment that is installed in the vehicle and road side equipment through wireless channels of communication. on board equipment is system that have a memory which initialization information is stored, it loads physical layer and MAC layer, LLC layer, L7 layer in turn. In the upper, it should analyze the various commands that are sent from roadside base stations, and carry out the operation which is in accordance with the command. and also it designs the structure of protocol stack which is TRM Layer loaded that is to initialize on L7 layer and MAC layer and efficiently designs operation between on board equipment and the road side equipment.

  • The existing DSRC(Dedicated Short Range Communication) scheme has a limitation in providing various services through short-range wireless communication. Therefore, it is necessary to develop an intelligent WAVE/DSRC hybrid wireless platform that can improve data transmission speed and extend the effective communication range. This paper introduces WAVE/DSRC integrated platform technology using WAVE(Wireless Access in Vehicle Environments) to overcome the disadvantages of DSRC. First, the desinged software configuration of the WAVE/DSRC integrated platform is described. Then each task operation scheme and WAVE software design are described. By applying the WAVE/DSRC integrated platform, we can compensate the shortcomings of DSRC. It can provide more accurate and reliable services.
