VIVAGr is a graphical-oriented, real-time visualization tool for vehicular ad-hoc network connectivity graphs. It enables the effective synthesis of structural, topological, and dynamic characteristics of VANnet graphs, with a variety of parameters that affect the characteristics of a vehicular ad hoc network (wireless range, mobility models, road-network topology, market penetration ratio, and exhibited interference). The tool represents all active connections in real-time mode using mobility traces using a visual encoding syntax to represent semantic meanings and the effect of mobility and topology on vehicular network specific properties.

Our design allows researchers to explore and understand problems and issues related with vehicular ad-hoc networks and seek answers to several key questions about the shape and the large-scale behavior of vehicular communication network.
