Data Dissemination with Drop Boxes

For data dissemination using vehicular ad hoc networks (VANETs), it is essential to determine the end-to-end (e2e) delay, the packet dropping probability (PDP), the number of vehicles required, and the size of the vehiclespsila buffers needed to hold packets. In this paper, we study the impact of the above mentioned parameters and report original simulation results in a typical city scenario based on a 3x3 Manhattan grid. In addition, we also study the efficiency of our approach under varying degrees of market penetration of instrumented vehicles, hence establishing useful thresholds in realistic scenarios. Finally, by introducing different configurations of drop boxes, we show significant reduction in e2e delay and PDP.
