Towards Standardization of Millimeter Wave Vehicle-to-Vehicle Networks: Open Challenges and Performance Evaluation
share
IEEE 802.11bd and 3GPP NR V2X represent the new specifications for the next generation of Vehicle-to-Vehicle (V2V) networks, which will foresee the integration of the millimeter wave band in vehicular operations to address the high data rates and low latency requirements of V2V communications. In this paper, we review the latest standard developments and present an overview of the mmWave-specific challenges that 802.11bd and NR V2X will have to address. To the best of our knowledge, our work is the first that considers a full-stack end-to-end approach for the design of V2V networks, discussing open issues that span from the physical to the higher layers, and reporting the results of an end-to-end performance evaluation that highlight the potentials of mmWaves for V2V communications.
