Data Scheduling for Vehicular Ad-hoc Networks Augmented with Road Side Units

Yiqing Gui and Edward Chan

Abstract—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, we propose a motion prediction based scheduling scheme for vehicle to RSU data access which enables cooperative work among a set of Road Side Units. Vehicle requests can be transferred and thus balanced among a group of RSUs, which helps to result in better scheduling performance. Simulation results show that our scheme outperforms simple scheduling schemes under various circumstances. We also examined the extension of our scheme to the case of multi-item requests.
