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.

摘要

与连接路边基础设施的路边基础设施协同运行的车载自组织网络（VANETs）是车辆通信领域中一个新兴的无线通信技术领域。对于VANETs而言，基于IEEE 802.11p的ITS-G5是全球通信的关键标准之一。这项研究工作将ITS-G5与基于蜂窝的5G测试网络（5GTN）集成在一起。由此产生的先进异构车载网络（VN）测试平台成为车辆与路边基础设施之间交通安全的有效平台。该测试平台网络提供了一个灵活的框架，以利用基于车辆的天气数据和道路观测信息，为VANETs创建一个支持实时智能交通服务的服务架构。本文研究的网络旨在通过提供实时天气预报、道路摩擦信息和道路交通相关服务来提高道路安全性。本文介绍了在芬兰北部实施的一个实际测试平台以及考虑车辆速度、延迟、有效传输时间和吞吐量的异构VANETs的现场测量结果。现场测量结果是在一个支持特殊道路天气服务的先进混合VANET系统中获得的。基于现场测量结果，我们提出了一种利用道路天气信息的综合混合车载网络基础设施的高效解决方案。
