Riassunto analitico
Modern vehicular communication technology, particularly IEEE 802.11p, plays a pivotal role in Intelligent Transportation Systems (ITS), enabling low-latency, vehicle-to-everything (V2X) communication. A key component of ITS safety applications is the dissemination of Cooperative Awareness Messages (CAMs), which allow vehicles to share real-time status information. These messages are essential for collision avoidance and traffic efficiency, as each vehicle is responsible for broadcasting its CAMs. Additional situational awareness is provided by Cooperative Perception System (CPS) messages, where vehicles integrate data from their Advanced Driver Assistance Systems (ADAS) and onboard cameras to extend perception beyond line-of-sight limitations.
Despite the advantages of CAMs and CPS messages, the decentralized nature of their dissemination poses challenges such as redundancy, network congestion, and limited perception in complex urban environments. To address these limitations, we propose an infrastructure-based approach that centralizes CAM dissemination. Leveraging a novel infrastructure deployed at the MASA Living Lab, our solution enhances vehicular communication by aggregating and distributing CAMs through a dedicated roadside system. This approach improves message reliability, reduces redundant transmissions, and optimizes network efficiency, ultimately contributing to safer and more efficient ITS ecosystems.
