Timely data dissemination to vehicles is a core function in Vehicular Ad-hoc NETworks (VANETs), and the use of Road Side Unit (RSU) has been proposed by researchers to augment vehicle to vehicle communication. RSU can serve as data buffer point from which vehicles can request to access data items stored there. When scheduling vehicle to RSU data access, the mobility pattern of vehicles can be made use of to facilitate multi-RSU data dissemination. In this paper, the authors propose a motion prediction based scheduling scheme for vehicle to RSU data access which enables cooperative work among a set of Road Side Units.
