Conclusions and Future Research Directions

Since the end of the last century, vehicle-to-vehicle (V2V) communications have received increasing attention. Aiming at properly and successfully supporting the design and performance evaluation of V2V wireless communication systems, both the comprehensive understanding of V2V wireless communication channel characteristics and the accurate and easy-to-use V2V wireless communication channel models are indispensable. In this chapter, the contents of the proposed channel models are adequately summarized. Then, important research directions, which can be regarded as the guidelines for developing more precise and easy-to-use models for V2V wireless communication channels, are presented from the perspectives of channel measurement, channel modeling, as well as channel application.
