Routing in Vehicular Networks: Feasibility, Modeling, and Security
Vehicular networks are sets of surface transportation systems that have the ability to communicate with each other. Such networks offer the potential for fast and accurate driving information (e.g., traffic, accidents, and emissions) that would otherwise be more difficult to disseminate. Safety applications include accident avoidance and cooperative driving. Nonsafety applications include traffic information, toll service, Internet access, cooperative entertainment, and so on. There are several possible network architectures 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. Vehicular networks consist of nodes-vehicles equipped with wireless communication devices, GPS, digital maps, and optional sensors for reporting the vehicle condition. Vehicles exchange information with other vehicles as well as with access points (base stations) within their radio range. Some special properties of these networks, such as high mobility, network partitioning, and constrained topology, differentiate them from other types of wireless networks. In this article, the authors investigate the following: the extent to which the vehicular network characteristics can determine the performance of routing; how current wireless technologies (e.g., WiFi, UWB, WiMax, and cellular) can be used to support vehicular networks; related studies on vehicular network architectures and routing; and how feasible it is to maintain a level of security in such networks. They also discuss how the vehicular network properties can affect the impact of malicious attacks, as well as some general mitigation schemes.
