A survey of V2X communication technique for supporting platooning

Recently, autonomous vehicles using artificial intelligence have been attracting attention. Beyond the autonomous driving, research about platooning is being carried out to achieve driver convenience and increase vehicle capacity on the road and fuel reduction. To carry out the platooning, various data such as vehicle driving, sensing, and control data between vehicles must be exchanged. Due to the dynamic nature of intervehicle communication, bandwidth is limited, and it is difficult to transfer safety data successfully. This paper studies the existing inter-vehicle communication techniques and analyzes how these techniques overcome the unstable communication environment. In the result, we present important factors to efficiently utilize the bandwidth and considerations to support platooning.
