Map update application: Performance measurements on a highway scenario

Abstract:

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. © 2012 IEEE.
