Vehicular Ad Hoc NETworks (VANETs) are a peculiar subclass of mobile ad hoc networks that raise a number of technical challenges, notably from the point of view of their mobility models. In this paper, the authors provide a thorough analysis of the connectivity of such networks by leveraging on well-known results of percolation theory. By means of simulations, they study the influence of a number of parameters, including vehicle density, proportion of equipped vehicles, and radio communication range. They also study the influence of traffic lights and roadside units. Their results provide insights on the behavior of connectivity. They believe this paper to be a valuable framework to assess the feasibility and performance of future applications relying on vehicular connectivity in urban scenarios.
