Modeling and Performance Analysis of Medium Access Control Schemes for Drive-Thru Internet Access Provisioning Systems

Broadband Internet access provisioning in vehicular environments requires establishing on-the-fly connectivity between mobile vehicles and stationary Internet gateways deployed along roadways. The literature encloses various works revolving around vehicle-to-infrastructure (V2I) communication schemes designed to cater for this objective. In this paper, two novel complexity minimal MAC schemes are proposed for drive-thru Internet (DTI) access provisioning systems. The first of these schemes is called the random vehicle selection (RVS) scheme, and the second is called the least residual residence time (LRT) scheme. A mathematical framework is established with the objective of modeling a vehicle´s onboard unit´s buffer and evaluating its performance under RVS and LRT, in terms of several quality-of-service metrics. Extensive simulations are conducted for the purpose of verifying the proposed models´ validity and accuracy.
