Abstract

Vehicular communication needs are steadily increasing. While some data is unique for every vehicle, other data, like updates, have to be distributed to many cars. However, the sole reliance on cellular networks unnecessarily increases data costs and data usage. A vehicular cooperative downloading scheme utilizes additional communication technologies, like direct communication between vehicles, to exchange data. For an efficient use of this communication channel, enough data has to be present in the vehicles, which can be exchanged. A seeding strategy introduces parts of the update into the vehicles to start the cooperative downloading procedure. However, if too few data chunks are present, the direct communication link is not fully utilized, while over-provisioning the vehicles with data unnecessarily increases cellular usage. In this paper, we first introduce an initial seeding strategy and find its optimal results for a baseline comparison. We then use deep reinforcement learning to develop a strategy which continuously determines how much data needs to be added to the vehicle fleet at any time, optimizing the overall system's performance. Our results consider various update sizes and mobility scenarios and show that proximal policy optimization is a suitable approach to lower the usage of cellular communication in a cooperative downloading scheme. We can reduce the use of cellular networks by more than 98%, while continuously seeding improves the best initial seeding approach by more than 60%.
