Guest editorial: On-the-road communications

Recent developments in the automotive and telematics industries have led to a new emerging domain known as vehicular wireless networks. Vehicular wireless networks enable several new classes of vehicular applications that can improve traffic safety, driver convenience, roadway efficiency, and facilitate many types of in-vehicle services. Vehicular ad hoc networks (VANETs) involve not only vehicle-to-vehicle (V2V) but also vehicle-to-infrastructure (V2I) communications.
