Abstract This paper surveys the field of vehicle-to-vehicle (V2V) communication channels. Motivated by intelligent transportation systems and vehicular safety, V2V research has proliferated in recent years. We provide a short description of V2V communication systems, and the importance of key channel parameters. This is followed by a discussion of basic channel characteristics—the channel impulse response and channel transfer function, and their statistical description—and how V2V channels differ from the more familiar cellular radio channel. Modeling of the V2V channel is covered by a review of the literature on V2V channels, addressing path loss, delay spread, and Doppler spread. We describe the two most popular methods for modeling V2V channels, tapped-delay line models and geometry-based models, then briefly discuss multiple-antenna channels and the crucial V2V channel characteristic of non-stationarity. A potential channel classification scheme for V2V channels is given, and some recent results on the channel within parking garages, and on sloped terrain, are provided. We end the paper with a short discussion of what may come next in this vibrant field.
