Vehicular ad hoc networks (VANETs) can help to increase safety and comfort ‘on the road’. As an element for active, i.e., preventive safety, these VANETs can efficiently warn and inform drivers via direct wireless intervehicle communications. Thereby, the range of awareness of a driver is extended from current line-of-sight to the radio range of a wireless transceiver. With multi-hop communication, each vehicle can benefit from the locally sensed data of surrounding vehicles or from multi-hop access opportunities. Clearly, sensing, disseminating and retrieving information on the current surrounding shows a potential for improving transport efficiency and comfort. Recently, the promises of wireless communications to support vehicular safety applications have led to several national/international projects around the world: DSRC, VSC, VII in USA, C2CCC in Europe, AVS in Japan or Network on Wheels in Germany, to name a few. All these efforts have as a main goal to improve safety in vehicular environments by the use of wireless communications, but also consider transport efficiency, comfort and environment. In comparison to other communication networks VANETs have unique requirements with respect to applications, types of communication, self-organization and security. In the context just described, the proposed tutorial has two main goals:
  • To present a detailed description of the state of the art of VANETs pointing to research, projects and standardization efforts that have been done.
  • To outline the challenges of the current technologies and to discuss open issues and directions of further research in this field.
