Routing in Vehicular Networks : Feasibility , Security and Modeling Issues

Vehicular networks are sets of surface transportation systems that have the ability to communicate with each other. There are several possible network architectur es to organize their in-vehicle computing systems. Potential schemes may include vehicle-to-vehicle ad-hoc networks, wired backbone with wireless last-hops, or hybrid architectures using vehicle-to-vehicle communications to augment roadside communication infrastructures. Some special properties of these networks, such as high mobility, ne twork partitioning and constrained topology, differentiate them from other types of wireless networks. In this article we revisit most of the important studies on designing architectures and discussing routing aspects for such networks. Moreover, we provide the basic concepts of traffic flow theory and we discuss the major security concerns appearing in vehicular networks.
