Co-simulated Digital Twin on the Network Edge: the case of platooning
2022
This paper presents an approach to create high fidelity Digital-Twin models for distributed multi-agent cyber-physical systems based on the combination of simulating components, generated from different modeling languages, each tailored for the specific domain of the subsystem. The approach specifically addresses the wireless communication domain, exploiting a Python module as a simulating component to evaluate the impact of network delay among the distributed elements of the system under analysis. A case study with a platoon of four vehicles following a leading car, all modeled in Simulink, is used to show the applicability of the approach, allowing the comparison between a Vehicle-to-Vehi…
Reconstrucción del entorno radio para comunicaciones en agrupaciones de vehículos
2020
Los pelotones de vehículos son grupos de vehículos que viajan juntos, manteniendo una distancia constante entre ellos. Los pelotones suelen necesitar comunicaciones inalámbricas sólidas y fiables para mantener su estructura y realizar maniobras coordinadas. Cuando el pelotón es asistido por la infraestructura a través de una comunicación celular vehículo a todo (V2X), uno de los factores críticos es reducir la latencia de la comunicación. En este trabajo se explora el uso de una técnica de interpolación espacial, concretamente el Kriging Ordinario, como mecanismo para reducir la sobrecarga de señalización en la etapa de adquisición de información del canal, lo que puede repercutir en la prá…
Application of Radio Environment Map Reconstruction Techniques to Platoon-based Cellular V2X Communications
2020
Vehicle platoons involve groups of vehicles travelling together at a constant inter-vehicle distance, with different common benefits such as increasing road efficiency and fuel saving. Vehicle platooning requires highly reliable wireless communications to keep the group structure and carry out coordinated maneuvers in a safe manner. Focusing on infrastructure-assisted cellular vehicle to anything (V2X) communications, the amount of control information to be exchanged between each platoon vehicle and the base station is a critical factor affecting the communication latency. This paper exploits the particular structure and characteristics of platooning to decrease the control information exch…
