A novel ICN-based communication bus for Intelligent Transportation Systems

This work presents a novel information-centric communication bus for Intelligent Transportation Systems, namely BONVOYAGE Communication System. Based on the Internames principle (i.e., an evolution of the well-known Information- Centric Networking paradigm), it offers a scalable and distributed dissemination of real-time contents through standardized interfaces, request-response and publish-subscribe schema, while ensuring interoperability across borders. To prove its suitability in real scenarios, the main functionalities of the BONVOYAGE Communication System (including namespace, data processing, and caching) have been properly designed and characterized in order to effectively disseminate travel-centric data (i.e. contents of interest of Intelligent Transportation Systems) formatted according to DATEX II specifications. Experimental tests demonstrate that the proposed solution outperforms baseline dissemination mechanisms in terms of processing complexity, communication latencies, and bandwidth consumption
