The autonomous vehicle is being considered as the technology of the future. Many companies and researchers are working toward making this a reality. The growing popularity of the Internet of Things (IoT) and advances in sensor technology play an important role. Wireless communication is essential for autonomous vehicles to share information with each other. With limited spectrum available for wireless communication for appropriate applications, researchers are constantly working toward finding solutions to use limited wireless spectrum efficiently. In such an effort, the authors of this research paper study the use of millimeter wave (mmWave) communication for autonomous vehicles.

The authors present a framework for a vehicle mmWave system and discuss its advantages, limitations, and key design problems. Detailed design of the developed framework is presented for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) modes of communication. The authors also discuss message priority (for safety-critical and application-driven data), deployment plans, handover strategy, and the possibility of using directional communication over mmWave. The functionality and performance of the developed framework is studied through a developed prototype as well as a simulation. All of these aspects are discussed in detail. Limitations of this framework and open issues discussed in this paper can be used by interested researchers to carry out further research in this field.

I enjoyed reading this paper and find it complete: it first presents the necessity to go for mmWave communication for vehicular systems, and then the authors present the framework, discuss its functionality and performance (backed with simulation results), and discuss limitations of the developed framework and open research issues that can be picked up by interested researchers to take this research further. I would definitely recommend it to other researchers working in this field.
