DSRC(Dedicated Short Range Communication)는 안전 지향 애플리케이션에 대해 100개의 제어 채널을 사용하고 비안전 상용 애플리케이션에 대해 XNUMX개의 서비스 채널을 사용합니다. 그러나 대부분의 기존 다중 채널 방식에서는 모든 인접 차량이 비안전 서비스를 위한 서비스 채널로 전환하기 전에 안전 지향 데이터의 전체 업데이트를 위해 주기적으로(예: XNUMX밀리초마다) 제어 채널을 조정해야 합니다. 교통밀도가 높아질수록 안전 교환 간격도 늘어납니다. 결과적으로 트래픽 밀도가 높으면 제어 채널이 정체되는 동안 서비스 채널은 완전히 유휴 상태가 되는 경우가 많습니다. 우리는 모든 채널을 완전히 활용하여 동시 안전 및 비안전 통신을 제공하는 RSU 지원 다중 채널 조정 MAC(RAMC) 프로토콜을 제안합니다. RSU(Roadside Unit)의 무선 범위 내에서 차량은 모든 서비스 채널에 자유롭게 주파수를 맞출 수 있습니다. RSU는 제어 채널과 서비스 채널 모두에서 전송되는 모든 안전 메시지를 모니터링합니다. RSU는 주기적으로 모든 채널의 모든 인접 차량에 통합 교통 보기 보고서를 방송합니다. 따라서 차량은 적절하고 시기적절한 안전 인식을 유지하면서 비안전 애플리케이션에 대한 높은 처리량을 달성해야 하는 한 서비스 채널에서 작동할 수 있습니다. 시뮬레이션 결과는 제안된 RAMC 프로토콜이 다양한 트래픽 밀도 조건에서 높은 안전 메시지 전달 비율을 유지하면서 매우 높은 비안전 사용 비율을 지속적으로 달성한다는 것을 보여줍니다.

Abstract: Dedicated Short Range Communication (DSRC) employs one control channel for safety-oriented applications and six service channels for non-safety commercial applications. However, most existing multi-channel schemes require all neighboring vehicles periodically (e.g. every 100 milliseconds) tune to the control channel for a full update of safety-oriented data before they can switch to the service channels for non-safety services. The safety exchange interval increases with the increase of traffic density. Consequently, under high traffic densities, the service channels are often completely idle while the control channel is congested. We propose a RSU Assisted Multi-channel Coordination MAC (RAMC) protocol that fully utilizes all channels to provide simultaneous safety and non-safety communications. Within the radio range of a roadside unit (RSU), vehicles are free to tune to any service channel. The RSU monitors all the safety messages being transmitted in both the control and service channels. Periodically, the RSU broadcasts a consolidated traffic view report to all neighboring vehicles in all channels. Therefore, a vehicle can operate in a service channel as long as it needs to achieve high throughput for non-safety applications, while maintaining adequate and timely safety awareness. Our simulation results show that the proposed RAMC protocol consistently achieves very high percentage of non-safety usage, while maintaining high safety message delivery ratios in various traffic density conditions.
