Enabling Future Maritime Traffic Management: A Decentralized Architecture for Sharing Data in the Maritime Domain
Year: 2025
Type: article
Abstract: Digitalization is transforming the maritime sector, and the amount and variety of data generated is increasing rapidly. Effective data utilization is crucial for data-driven services such as for highly automated maritime systems and efficient traffic coordination. However, these applications depend on heterogeneous, distributed data sources managed by different actors, making secure and sovereign information sharing difficult. This paper investigates how maritime data can be exchanged reliably and securely without jeopardizing data sovereignty. Based on the existing literature, we identify the main challenges and current research gap in sharing maritime information, emphasizing the importance of data availability. From this, we derive requirements for a secure and sovereign infrastructure for data exchange. To address these challenges, we propose a fully decentralized architecture for the maritime sector based on the concept of a data space. Our approach integrates protocols to improve data availability while minimizing data volume, considering maritime constraints such as volatile connectivity, low bandwidth and existing standards. We evaluate our architecture through a maritime traffic management case study and demonstrate its ability to enable secure and sovereign exchange of heterogeneous data. The results confirm that our solution reliably supports distributed data collection and enables data-driven, value-added services, which in turn will improve the safety and efficiency of the maritime domain in the near future.
