Purpose – The past decade has witnessed a growing interest in vehicular networking and its myriad applications. The initial view of practitioners and researchers was that radio-equipped vehicles can keep the drivers informed about potential safety risks and can enhance their awareness of road conditions and trafﬁc-related events. This conceptual paper seeks to put forth a novel vision, namely that advances in vehicular networks, embedded devices, and cloud computing can be used to set up what are known as vehicular clouds (VCs). Design/methodology/approach – The paper suggests that VCs are technologically feasible and that they are likely to have a signiﬁcant societal impact. Findings – The paper argues that at least in some of its manifestations, the ideas behind VCs are eminently implementable under present day technology. It is also expected that, once adopted and championed by municipalities and third-party infrastructure providers, VCs will redeﬁne the way in which pervasive computing and its myriad applications is thought of. Research limitations/implications – This is a new concept for which a small-scale prototype is being built. No large-scale prototype exists at the moment. Practical implications – VCs are a novel concept motivated by the realization of the fact that, most of the time, the tremendous amount of computing and communication resources available in vehicles is underutilized. Putting these resources to work in a meaningful way should have a signiﬁcant societal impact. Social implications – The main goal of this paper is to introduce and promote the concept of VCs, a non-trivial extension, along several dimensions, of the by-now “classic” cloud computing. The paper shows that the concept of VCs is feasible as of today – at least in some of its manifestations – and that it can have a signiﬁcant societal impact in the years to come. Originality/value – The idea of a VC is novel and so are the potential applications that are discussed in the paper.

1. The vehicular model The past 20 years have seen an unmistakable trend to make the vehicles on our roads and city streets smarter and the driving experience safer, less stressful and, consequently, more enjoyable. A typical car or truck today is likely to contain at least The ﬁrst author was supported, in part, by NSF grant CNS 0721586.

some of the following devices: an on-board computer, a GPS device, a radio transceiver, a short-range rear collision radar device, and a camera, supplemented, in high-end models, by a variety of sophisticated sensing devices that can alert the driver to all sorts of mechanical malfunctions and road conditions. In addition, some high-end vehicles already offer the convenience of an event data recorder (EDR) that collects transactional data from most if not all of the vehicle sub-assemblies. It is, perhaps, not widely known that some GM vehicles as old as model year 1994 were equipped with an EDR-like device able to store retrievable data. In general, the EDRs are intended to be tamper proof, very much like the well-known black boxes on board commercial and military aircraft. In...
