Abstract

Supporting handover functionality in V2I communication environments is important to provide higher quality service to users on the road. Wireless Access in Vehicular Environments(WAVE) standards define some features that devices can communicate with each other more efficiently in vehicular environments but they do not include handover function for providing effective V2I services. In this paper, we introduce a handover scheme in WAVE system and show the performance result of proposed scheme.

차량-인프라 간(V2I, Vehicle-to-Infrastructure) 통신 환경에서 도로 상의 차량 및 사용자들에게 보다 양질의 서비스를 제공하기 위해서는 차량이 기지국 간을 이동 시에도 데이터 흐름이 끊어지지 않도록 하는 핸드오버 기능의 제공이 필요하다. WAVE(Wireless Access in Vehicular Environments) 표준은 차량 환경에서 장치 간에 보다 효과적인 통신을 하기 위한 여러 기능들을 정의하고 있지만, V2I 서비스의 품질을 향상시키기 위한 핸드오버 기능은 포함하고 있지 않다. 본 논문에서는 WAVE 통신 시스템에 기반을 둔 핸드오버 메커니즘을 소개하고, 실제 도로 상에서 해당 메커니즘이 구현된 기지국 및 단말기를 이용한 실험을 통해 도출된 성능 분석 결과를 보인다.
