  Abstract

Various convergence technologies that utilize eMMB(Enhanced mobile broadband), mMTC(Massive Machine Type Communication), and URLLC(Ultra-Reliable Low Latency Communication) characteristics of 5G mobile communication are rapidly developing. In particular, autonomous vehicles have received much attention for their 5G convergence technology, and in recent 3GPP Release 16, LTE-based Vehicle to Everything(V2X) communication has been standardized as 5G NR(New Radio) based sidelink. Vehicular Fog Computing is a transient local cloud consisting of autonomous driving platooning that is needed to quickly collect and analyze large amounts of delay-sensitive sensor data, etc. For safe vehicle platooning, the integrity of driving and safety data within Vehicular Fog Computing should be ensured. Vehicular Blockchain is created and maintained in an inter-vehicle P2P network to help ensure the integrity of the data. However, interference in inter-vehicle wireless communication, and the instability of connection due to variable vehicle moving speed, make it difficult to synchronize blockchain data. In this paper, we propose and implement a method utilizing LT codes to synchronize blockchain data between vehicles in a Vehicular Fog Computing environment with reliable and fast. Based on this, we bulid a test bed and confirmed that it can be realized through experiments.
