Recently, as researches on VANET have actively progressed, the convenient and reliable services can be provided to the vehicles. In this paper, we propose the collaborative RSU scheduling scheme using multiple RSUs which are connected through a wired backbone. The proposed scheme efficiently disseminates both unsafety data and safety data, and reduces the deadline miss rate and the average response time. When safety data is occurred, it is send to previous RSU in advance and is scheduled by deadline and reception rate. We provide the prevention technology for unsafety data when the workload is occurred in RSU because it is on-demand data processed by user requests. It is shown through performance evaluation that the proposed scheme outperforms the existing scheme in terms of the deadline miss rate and the average response time according to the number of vehicles and the velocities of vehicles. ■ keyword : ∣VANET∣RSU∣Scheduling∣Safety Data ∣Unsafety Data ∣ * 이 논문은 미래창조과학부 및 정보통신산업진흥원의 |
