Map update application: Performance measurements on a highway scenario

Road maps are important for several applications in vehicular networks. As a consequence, an updated map is essential for a proper behavior of such applications. In this paper, we focus on a map update application based on an infrastructure-to-vehicle communication with a high mobility. In order to understand the application´s behavior, we analyze different performance criteria: System Goodput, Packet Delivery Ratio, Delay, Fairness, and Fragmentation. We compare the application´s QoS behavior with three different flow densities (overloaded system, maximum system capacity, and under saturated system) and determinate a trade off between bandwidth (spectrum efficiency) and performance.
