DNN-Controlled Multi-Technology Platooning

Abstract

We look at platooning applications that leverage two wireless technologies for the coordination of vehicle movements. The first technology is DSRC (dedicated short-range commu- nications), based on IEEE 802.11p, which allows a distributed implementation of the platoon coordination. The second technol- ogy is 5G (and beyond). In the latter case, the platoon control algorithm is centralized in an edge computing facility close to the platoon (or in the cloud, if latency allows). Trying to maximize platoon performance and overcome the unpredictability of the radio channel, both radio access technologies are simultaneously active, and a deep neural network (DNN) is used to decide which of the two should be relied on for platoon control, at each point in time. The proposed platooning architecture is compared against previously proposed alternatives, investigating performance with detailed simulation tools. Results show significant advantages in terms of accuracy and safety in inter-vehicle distance for all vehicles within the platoon.
