Connected Vehicles: V2V and V2I Road Weather and Traffic Communication Using Cellular Technologies

Abstract

There is a continuous need to design and develop wireless technologies to meet the increasing demands for high-speed wireless data transfer to incorporate advanced intelligent transport systems. Different wireless technologies are continuously evolving including short-range and long-range (WiMAX, LTE, and 5G) cellular standards. These emerging technologies can considerably enhance the operational performance of communication between vehicles and road-side infrastructure. This paper analyzes the performance of cellular-based long-term evolution (LTE) and 5GTN (5G Test Network) in pilot field measurements (i.e., vehicle-to-vehicle and vehicle-to-infrastructure) when delivering road weather and traffic information in real-time environments. Measurements were conducted on a test track operated and owned by the Finnish Meteorological Institute (FMI), Finland. The results showed that 5GTN outperformed LTE when exchanging road weather and traffic data messages in V2V and V2I scenarios. This comparison was made by mainly considering bandwidth, throughput, packet loss, and latency. The safety critical messages were transmitted at a transmission frequency of 10 Hz. The performance of both compared technologies (i.e., LTE and 5GTN) fulfilled the minimum requirements of the ITS-Assisted Road weather and traffic platform to offer reliable communication for enhanced road traffic safety. The field measurement results also illustrate the advantage of cellular networks (LTE and 5GTN) with a clear potential to use it heterogeneously in future field tests with short-range protocols, e.g., IEEE 802.11p.

Communication Delay Outlier Detection and Compensation for Teleoperation Using Stochastic State Estimation

“…In this scenario, numerous approaches to the communication method can be used such as (but not limited to) 5G/LTE and DSRC [ 37 ] with appropriate protocols, e.g., SAE J2735 [ 38 ]. As for the common failure scenarios for using such wireless communication methods, the performance of the connectivity can be degraded due to systematic failures, low sensitivity, and even weather conditions [ 39 ]. Therefore, careful monitoring of the instant state of communication is required, especially when implementing teleoperation of the vehicle.…”

Secure Vehicular Networking: Architectures, Applications, Attacks, and Challenges

“…In the event that tampering is detected, the device is programmed to erase all stored keys and information. This self-erasure mechanism is a vital security measure, preventing compromised data from falling into the hands of attackers and ensuring the continued security of the vehicle's communication systems [27].…”

State-of-the-Art Device-to-Device Communication Solutions

“…Here, researchers review solutions that use cellular networks. In [50], the authors present a complete collaborative intelligent transportation system consisting of a framework shared between different components in C-ITS, which realizes the communication between vehicles in V2I and V2V networks when exchanging traffic and road weather information in cellular networks. Experimental networks 5GTN and LTE were used for performance analysis.…”
