Characterization of Packet-Level Measurements for Vehicular Wireless Networks

摘要

A comprehensive understanding of the fading effect on vehicular communications is essential for reliable intelligent transportation system (ITS). Dozens of experiments were performed in the real urban area to collect various types of vehicular wireless data measurements. Then a simulation model of radio link between double mobile nodes was proposed. Based on the real measured data, the proposed model, and the existing model are all applied to the simulator for comparison. It is shown that by evaluating the packet level performance for double mobile vehicles in an urban area, the proposed model performed better. Significant realism can be added to existing systems with clear implications on the design of upper layer protocols by modeling the fading characters for vehicular communications.
