Vehicular cloud networks: Architecture and security

Cloud computing has been widely adopted across the IT industry due to its scalable, cost-effective, and efficient services. It has many applications in areas such as healthcare, mobile cloud computing (MCC), and vehicular ad hoc networks (VANET). Vehicular cloud networks (VCN) is another application of cloud computing which is a combination of cloud and VANET technologies. It is composed of three clouds named vehicular cloud, infrastructure cloud, and traditional IT cloud. In this chapter, the three clouds involved in VCN are presented using a three-tier architecture, and the security issues related to each tier are described in detail. After describing the detailed architecture of VANET, their components, and their important characteristics, this chapter presents the architecture of VCN. It is followed by the detailed analysis of the threats to which each tier-cloud of VCN is vulnerable
