“…An effi cient and suitable wireless communication technology will be chosen such as to best capture the QoS requirements for a given vehicular application. However, there are numerous challenging issues which have to be answered in order to provide that HetVNETs be practically implemented [13,14,15]. One of the key topics is related to the intersystem handover, i.e.…”

“…In addition, network management is reduced to minimum, which enables immediate exchange of data among vehicles without complex signaling procedures. Nevertheless, there are numerous challenge issues which have to be solved to enable practical implementation of traffi c safety applications using DSRC, such as the following [7,8,9,12,15]: i) reliable delivery of messages, ii) high vehicle mobility (100-200km/h) and dynamic network topology, iii) scalability issues or performance degradation in presence of high vehicle density (the probability of data collisions increases rapidly with the large number of vehicles in a network, resulting in large end-to-end latency and low channel utilization) as a result of un-coordinated probabilistic CSMA/CA(Carrier Sense Multiple Access/Collision Avoidance) medium access control mechanism, iv) routing protocol issues as well as v) privacy and security issues. In addition, it is evident that not all vehicles will be equipped with IEEE 802.11p communication interfaces in the initial phase of traffi c safety applications implementation.…”

“…The measurement conditions were the same for all field measurements. For the V2I and V2V scenarios, the vehicle passed the RWSs and the other vehicle by making a connection with RWSs and sustaining the connection within communication range with the maximum possible data rate [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ].…”

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.

“…If degraded, it is important to anticipate this degradation so that countermeasures can be taken; e.g., reduce the level of driving automation with enough anticipation or simply stop a driverless vehicle until connectivity quality is resumed and allows for safe operation. The third unique property is the role of the road authority as another source and sink of information [7]. This comes with often closed, sometimes even proprietary, information technology (IT) systems needing integration in a MEC-enabled distributed computing V2X network architecture.…”

5G Cross-Border Operation for Connected and Automated Mobility: Challenges and Solutions

et al. 2019

The vision of cooperative, connected and automated mobility (CCAM) across Europe can only be realized when harmonized solutions that support cross-border traffic exist. The possibility of providing CCAM services along different countries when vehicles drive across various national borders has a huge innovative business potential. However, the seamless provision of connectivity and the uninterrupted delivery of services along borders also poses interesting technical challenges. The situation is particularly innovative given the multi-country, multi-operator, multi-telco-vendor, and multi-car-manufacturer scenario of any cross-border layout. This paper introduces the challenges associated to a cross-border deployment of communication technologies through the analysis of three use cases: tele-operated driving, high-definition map generation and distribution for autonomous vehicles, and anticipated cooperative collision avoidance. Furthermore, a set of 5G solutions have been identified to ensure that CCAM services can be supported efficiently in cross-border scenarios. Faster handover of a data connection from one operator to another, generalized inter-mobile edge computing (MEC) coordination, and quality of service (QoS) prediction are some of the solutions that have been introduced to reduce the uncertainties of a real 5G cross-border deployment.
