Vehicular communication management framework : a flexible hybrid connectivity platform for CCAM services

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

5G-MEC Testbeds for V2X Applications

Fifth-generation (5G) mobile networks fulfill the demands of critical applications, such as Ultra-Reliable Low-Latency Communication (URLLC), particularly in the automotive industry. Vehicular communication requires low latency and high computational capabilities at the network’s edge. To meet these requirements, ETSI standardized Multi-access Edge Computing (MEC), which provides cloud computing capabilities and addresses the need for low latency. This paper presents a generalized overview for implementing a 5G-MEC testbed for Vehicle-to-Everything (V2X) applications, as well as the analysis of some important testbeds and state-of-the-art implementations based on their deployment scenario, 5G use cases, and open source accessibility. The complexity of using the testbeds is also discussed, and the challenges researchers may face while replicating and deploying them are highlighted. Finally, the paper summarizes the tools used to build the testbeds and addresses open issues related to implementing the testbeds.publishedVersio

Cooperative Vehicular Platooning (Co-VP) is a paradigmatic example of a Cooperative Cyber-Physical System (Co-CPS), which holds the potential to vastly improve road safety by partially removing humans from the driving task. However, the challenges are substantial, as the domain involves several topics, such as control theory, communications, vehicle dynamics, security, and traffic engineering, that must be coupled to describe, develop and validate these systems of systems accurately. This work presents a comprehensive survey of significant and recent advances in Co-VP relevant fields. We start by overviewing the work on control strategies and underlying communication infrastructures, focusing on their interplay. We also address a fundamental concern by presenting a cyber-security overview regarding these systems. Furthermore, we present and compare the primary initiatives to test and validate those systems, including simulation tools, hardware-in-the-loop setups, and vehicular testbeds. Finally, we highlight a few open challenges in the Co-VP domain. This work aims to provide a fundamental overview of highly relevant works on Co-VP topics, particularly by exposing their inter-dependencies, facilitating a guide that will support further developments in this challenging field.info:eu-repo/semantics/publishedVersio

Safety-critical platooning function based on wireless communication using cooperative robots

Platooning define la conducción de un grupo de vehículos con un destino o dirección común, en la que el primer vehículo decide sobre la conducción (p. ej. aceleración, cambio de carril, desvío, etc.) y los demás se restringen a seguirlo. Estos vehículos pueden ser conducidos por un ser humano o de forma automática. Además, los vehículos comparten información entre sí permitiendo mantener una distancia de seguridad mínima entre ellos, lo que reduce el consumo de combustible y compacta el tráfico en las carreteras sin incrementar el riesgo de colisiones. Esta tesis propone una serie de escenarios basados en platooning y define un plano de control distribuido entre los vehículos que integra un protocolo de comunicación y un protocolo de control necesarios para conseguir realizar los escenarios de platooning, propuestos. Tanto los escenarios como la pila de protocolos para la comunicación que se han propuesto están basados en trabajo previo descrito en artículos de investigación. Estos artículos explican y prueban estándares y tecnologías adecuadas para desarrollar las funcionalidades de platooning definidas en la tesis. La principal tarea en esta tesis es el diseño de un protocolo de comunicación en alto nivel, capa de aplicación del modelo OSI, el cual define un conjunto de mensajes que al combinarlos permiten implementar una serie de funciones de platooning, en concreto permiten la implementación de los escenarios descritos en la tesis. Además de diseñar este protocolo de comunicación, se han implementado y probado en una plataforma real sencillas funciones de platooning. En la tesis también se analiza el protocolo, se buscan soluciones para soportar fallos de comunicación en la implementación y se evalúa la actuación de la implementación en base a unas métricas previamente definidas. Los test realizados sobre la implementación y los resultados obtenidos en la evaluación muestran que el protocolo diseñado permite ejecutar correctamente los escenarios de platooning deseados
