Efficient V2V Communication Scheme for 5G mmWave Hyper-Connected CAVs

Abstract

Connected and Autonomous Vehicles (CAVs) require continuous access to sensory data to perform complex high-speed maneuvers and advanced trajectory planning. High priority CAVs are particularly reliant on extended perception horizon facilitated by sensory data exchange between CAVs. Existing technologies such as the Dedicated Short Range Communications (DSRC) are ill-equipped to provide advanced cooperative perception service. This creates the need for more sophisticated technologies such as the 5G Millimetre-Waves (mmWaves). In this work, we propose a distributed Vehicleto-Vehicle (V2V) mmWaves association scheme operating in a heterogeneous manner. Our system utilises the information exchanged within the DSRC frequency band to bootstrap the best CAV pairs formation. Using a Stable Fixtures Matching Game, we form V2V multipoint-to-multipoint links. Compared to more traditional point-to-point links, our system provides almost twice as much sensory data exchange capacity for high priority CAVs while doubling the mmWaves channel utilisation for all the vehicles in the network.

A City-Scale ITS-G5 Network for Next-Generation Intelligent Transportation Systems: Design Insights and Challenges

“…The cloud-based service will be responsible for recording city-scale data, interconnecting the different FOs and Fog Areas and pushing city-scale policies in the entire network. Some more details about this system architecture can be found in [16,20,17,18]. In the next section, we will describe in greater detail the testbed components that we have already designed and deployed around the City of Bristol.…”

A hybrid dual-mode trust management scheme for vehicular networks

“…When a sender node sends a false message, its claim validation (V c ) yields zero, consequently, its credit value C rural is decremented by a as shown in equation (9). Whenever the credit value is updated, it is validated by equation (10) to obtain the final credit C of the node. If the value of C rural reaches zero, the node is revoked…”

“…However, they experience several limitations and encounter network degradation. Some schemes are unable to ensure message reliability 9,10 or maintain nodes' privacy. [11][12][13][14] In addition to that, many solutions rely on central authorities [11][12][13][15][16][17] such as roadside units (RSUs) which are costly and susceptible to physical attacks, besides they increase computational complexity.…”

Adaptive fuzzy‐based message dissemination and micro‐artificial bee colony algorithm optimised routing scheme for vehicular ad hoc network

“…A well-organised V2V communication method was displayed by Mavromatis et al [22] for 5G MmWave hyper-connected connected and autonomous vehicles (CAVs). In a heterogeneous way, the work had proposed a distributed V2V mm-wave association plot working.…”
