In this paper, the authors study random access in a drive-thru scenario, where roadside Access Points (APs) are installed on a highway to provide temporary Internet access for vehicles. They consider Vehicle-To-Roadside (V2R) communications for a vehicle that aims to upload a file when it is within the APs' coverage ranges, where both the channel contention level and transmission data rate vary over time. The vehicle will pay a fixed amount each time it tries to access the APs, and will incur a penalty if it cannot finish the file uploading when leaving the APs. First, they consider the problem of finding the optimal transmission policy with a single AP and random vehicular traffic arrivals.
