Heterogeneous (ITS-G5 and 5G) Vehicular Pilot Road Weather Service Platform in a Realistic Operational Environment

Abstract

VANETs (Vehicular Ad hoc Networks) operating in conjunction with road-side infrastructure connecting road-side infrastructure are an emerging field of wireless communication technology in the vehicular communication’s domain. For VANETs, the IEEE 802.11p-based ITS-G5 is one of the key standards for communication globally. This research work integrates the ITS-G5 with a cellular-based 5G Test Network (5GTN). The resulting advanced heterogeneous Vehicular Network (VN) test-bed works as an effective platform for traffic safety between vehicles and road-side-infrastructure. This test-bed network provides a flexible framework to exploit vehicle-based weather data and road observation information, creating a service architecture for VANETs that supports real-time intelligent traffic services. The network studied in this paper aims to deliver improved road safety by providing real-time weather forecast, road friction information and road traffic related services. This article presents the implementation of a realistic test-bed in Northern Finland and the field measurement results of the heterogeneous VANETs considering the speed of vehicle, latency, good-put time and throughput. The field measurement results have been obtained in a state-of-the-art hybrid VANET system supporting special road weather services. Based on field measurement results, we suggest an efficient solution for a comprehensive hybrid vehicular networking infrastructure exploiting road weather information.

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

“…Due to the rapid demand for high-data-rate ITS applications, the energy consumption model in vehicular networks was discussed in [ 15 ] based on combined optimal multi-function game theory and assignment issues. In Reference [ 16 ], the author briefly discussed the different factors that restrict the real-time implementation of cellular-based V2X radio resource management design issues.…”

“…To implement this arrangement, the VANET will require authorization to gain access to the cyberspace via existing LTE infrastructure, and this heterogenous system will increase the vehicular communication system’s efficiency. Nonetheless, mobile nodes in large numbers appear as a challenging aspect in this system [ 16 , 17 , 18 , 19 , 20 ]. Hence, the field measurements that were performed and studied in this paper involve a combination of an improved clustering framework, called multi-parallel processing, with multiband OFDM (MP-MBOFDM).…”

Deployment and Analysis of Cooperative Intelligent Transport System Pilot Service Alerts in Real Environment

“…The delay between transmission and receiving of messages depends on the load on channel, size of message, data-rate, traffic density and other aspects. More details can be found in the study [8] in which the acceptable latency for road traffic safety applications was established to 100ms that follows the measurement frequency of 10Hz. We use a resulting metric of their latency update in order to enumerate the scope to which operational safety functionality that is affected by the loss of packet.…”

“…For example, the systems such as intersection points or traffic accidents or long queues can be notified by using CAM messages in vehicular networking. The author in [8,9] made a comparison between ITS-G5 and WAVE and provide valued contribution for the improvement of channel access in VNs. The carrier frequency for of ITS-G5 and WAVE standard is 5.9GHz with few channels operate at slightly high or low frequencies.…”

On Differential Imaging Using Electromagnetic Simulation for Vehicular Antenna Signature Analysis

“…Current vehicle design relies on the placement of different sensors and antennae operating in frequency bands from 3 GHz up to millimetric waves (mmWave) for different purposes such as communications, sensing, and/or positioning. It is anticipated that the number of antennae and sensors installed on the vehicle surface will increase in future generations of vehicles as 5G-generation capabilities come to the fore [ 1 ]. The integration of sensors and antennae within the same vehicular platform is a complex task because the radiation pattern of these elements is influenced by the platform structure, other sensors and antenna installed, and how the induced surface current is distributed across the structure of the vehicle.…”
