The goal of this chapter is to introduce and review the challenges and opportunities offered by what promises to be the Next Paradigm Shift: From Vehicular Networks to Vehicular Clouds. It discusses the vehicular model, the key ingredient in vehicular clouds and offers an overview of vehicular networks. The chapter overviews the cloud computing and cloud services that has motivated the vision of vehicular clouds. It illustrates the power of the vehicular cloud concept by enumerating a number of possible application scenarios. The chapter discusses a number of security and privacy issues specific to vehicular clouds. Further, it discusses a number of fundamental research challenges in vehicular clouds and issues related to data aggregation in vehicular clouds. Turning to more empirical topics, the chapter reports on the first attempt at studying vehicular clouds empirically by way of simulation in NS‐3.
