“…In this scenario, each vehicle has on average 5.5 neighboring vehicles under LOS. The same scenario was implemented in [8] to evaluate 802.11ad for V2V communications. Following [8], the 802.11ad MAC is configured to accommodate 5 neighbors, and the duration of the interval for the data exchange with each neighbor is set to 50ms.…”

“…This study highlights important MAC inefficiencies of the current IEEE 802.11ad standard when utilized for V2V communications. In particular, [8] shows that the 802.11ad MAC processes for neighbor identification, beamforming and scheduling, generate significant overhead under vehicular scenarios. In addition, the current 802.11ad MAC results in many scheduling conflicts and coordination problems between different 802.11ad vehicular transmitters that significantly degrade the network performance.…”

“…The reference 802.11ad MAC results in that each 802.11ad transmitter needs to send approximately 5.800 control bytes to align its beam and schedule its transmissions to each one of its neighbors [8]. This includes all messages and handshaking needed to identify the neighbors, align beams and schedule the transmissions.…”

Future connected and automated driving applications can require larger bandwidth and higher data rates than currently supported by sub-6GHz V2X technologies (e.g. DSRC, ITS-G5 or C-V2X). This has triggered the interest in developing mmWave vehicular communications. However, solutions are necessary to solve the challenges resulting from the use of high-frequency bands and the high mobility of vehicles. This paper contributes to this active research area by proposing a sub-6GHz assisted mmWave MAC that decouples the mmWave data and control planes. The proposal offloads mmWave MAC control functions to a sub-6GHz V2X technology. This approach improves the operation of the MAC as the control functions benefit from the longer range, and the broadcast and omnidirectional transmissions of sub-6GHz V2X technologies. This study demonstrates that the proposed sub-6GHz assisted mmWave MAC reduces the control overhead and delay, and increases the spatial sharing compared to mmWave communications using a configuration of IEEE 802.11ad tailored to vehicular networks. The proposed MAC is here evaluated for V2V communications using 802.11p for the control plane and 802.11ad for the data plane, although it can be adapted to other technologies such as C-V2X and 5G NR-V2X.

INTRODUCTIONHEHICULAR networks will support the exchange of information between vehicles (Vehicle to Vehicle, V2V), and between vehicles and other nodes (V2X, Vehicle to Everything). The V2X standards ITS-G5, DSRC and ITS Connect are based on the 802.11p amendment to the IEEE 802.11 standard (amendment 6: Wireless Access in Vehicular Environments), and operate on the 5.9GHz or 760MHz bands. The 3GPP has also developed an adaptation of LTE to support sub-6GHz V2X communications known as C-V2X or LTE-V [1]. Sub-6GHz V2X technologies have been designed to support active safety services that require low data rates broadcast communications.The communication and bandwidth requirements of connected and automated driving applications (Section II.A) can challenge existing sub-6GHz V2X standards with limited bandwidth and data rates. This has motivated studies to design

Today, we witness an explosion in wireless networks that are accessed by high-performance mobile devices running a wide variety of demanding applications. The IEEE 802.11ad is a standard targeted at meeting these design requirements. Analytical modeling and performance evaluation is a crucial step needed for the evolution of any standard. In this paper, we model the service periods (SPs) of the IEEE 802.11ad hybrid medium access control as a special case of periodically gated queueing system (PGQS) with Bernoulli scheduling. We first state and prove some basic theorems related to the probability generating functions of the PGQS. Using these results, we derive the average delay and the delay variations (jitter) of packets belonging to SP of IEEE 802.11ad. We show that as the arrival rates increases, the delay increases linearly until the critical arrival rate, and beyond that, it becomes unbounded. Further, a practical scheme for the admission control mechanism of 802.11ad is also presented. To validate the model, analytical results are compared with simulation results.Trans Emerging Tel Tech. 2020;31:e3780.wileyonlinelibrary.com/journal/ett
