A Preliminary Study on the VANET Topology Characteristics from Propagation-Aware Traffic Flows Extracted from Measured Data

Understanding the dynamics of the network topology characteristics of vehicular networks (VANET) plays a key role to determine the feasibility of real-time safety and non-safety applications over VANET. Through the lenses of time-varying network metrics, including link duration, degree distribution, and number of connected components, this paper presents a preliminary analysis for VANET network topology characteristics for low and high traffic density. In our analysis, we integrate real-world buildings and obstacles along the propagation environments and measured data from the California Performance Measurement System (PeMS) database into a microscopic mobility model to obtain realistic traffic flows.
