Abstract
In the upcoming decade and beyond, the Cooperative, Connected and Automated Mobility (CCAM) initiative will play a huge role in increasing road safety, traffic efficiency and comfort of driving in Europe. While several individual vehicular wireless communication technologies exist, there is still a lack of real flexible and modular platforms that can support the need for hybrid communication. In this paper, we propose a novel vehicular communication management framework (CAMINO), which incorporates flexible support for both short-range direct and long-range cellular technologies and offers built-in Cooperative Intelligent Transport Systems’ (C-ITS) services for experimental validation in real-life settings. Moreover, integration with vehicle and infrastructure sensors/actuators and external services is enabled using a Distributed Uniform Streaming (DUST) framework. The framework is implemented and evaluated in the Smart Highway test site for two targeted use cases, proofing the functional operation in realistic environments. The flexibility and the modular architecture of the hybrid CAMINO framework offers valuable research potential in the field of vehicular communications and CCAM services and can enable cross-technology vehicular connectivity.
Highlights
In recent years, vehicles with autonomous driving functionalities have become more and more a reality on our roads
To integrate the Distributed Uniform Streaming (DUST) framework in the CAMINO framework, we have developed a series of publishers that can be used to trigger specific services at CAMINO-Core based on information that may derive from the CAN BUS or the sensors of the vehicle/Road-Side Unit (RSU) and a series of subscribers that bring the information from the different Intelligent Transport Systems (ITS) services in the vehicle/RSU
We have proposed the CAMINO framework, a flexible hybrid V2X
Summary
Vehicles with autonomous driving functionalities have become more and more a reality on our roads. CAMINO allows monitoring and logging of valuable information like transmitted and received messages, Global Navigation Satellite System (GNSS) data, triggering of events, etc This information can be used for real-time or offline analysis of various Key. The adoption of different technologies from different OEMs carries the risk of ending up with different groups of vehicles each using different communication technologies and as a result, only vehicles that belong to a certain group can communicate with each other. OEMs could integrate multiple technologies in their vehicles, which requires the use of flexible hybrid communication solutions such as CAMINO These solutions can provide the ability to use the same platform for supporting multiple communication technologies and using them in a dynamic way, acting as a low-complexity convergence layer for V2X interoperability and at the same time increasing reliability.
