This paper proposes Road-Side Units PlacementAlgorithm (RPA) to provide vehicles with the multihop Qualityof-service (QoS) data delivery in vehicular networks using infrastructurenodes, such as road-side units (RSUs) and relay nodes. We consider inbound delivery from RSU to vehicle. We definethe QoS of data delivery with the mean and standard deviationof end-to-end data delivery delay. In this paper, we propose aGreedy Set-Cover Algorithm for the selection of intersections toplace RSUs. We formulate the RSU deployment problem as theoptimal selection of a subset of road intersections for RSUs. Insimulation, this algorithm outperforms a uniform deployment andsatisfies the required QoS of data delivery in many cases.
