VANET Mobility Modeling Challenged by Feedback Loops

Free registration required

Executive Summary

VANET applications are often providing street traffic information to vehicles and drivers, regarding, for instance, traffic conditions and parking space availability. This information influences in turn the driving behavior in real-world settings. Mobility models used in current VANET simulations are mostly ignoring this feedback entirely. In cases the feedback is included; it is mainly based on ad-hoc approaches with lack of generality. With this paper, the authors contribute to the investigation of such feedback loops within VANETs by describing the levels at which feedback loops can be introduced, i.e., on strategic, tactical, and operational levels of mobility.
