Motivated by the recent surge in Vehicular Ad-hoc NETwork (VANET) research and the promise of high-impact applications such as safety, navigation and infotainment services, The authors consider the impact of mobility mis-modeling on the design and development of this class of distributed systems. Focusing on urban environments, they use a state-of-the-art car traffic simulator to extract some of the key connectivity metrics relevant for the design of a vehicle-to-vehicle traffic information system. They compare such metrics against those obtained from popular mobility models, such as the random waypoint model and the Manhattan mobility model.
