Data-Based Agreement for Inter-vehicle Coordination

Data-based agreement is increasingly used to implement traceable coordination across mobile entities such as ad-hoc networked (autonomous) vehicles. In our work, we focus on data-based agreement using database transactions where mobile entities agree on a set of coordinated tasks that need to be performed by them in an atomic way. Atomicity means that all transaction participants agree on a set of tasks which will be performed by them or no one of them is performing any task. The data about the agreed tasks and their corresponding stakeholders are kept in local databases as a proof for the obtained agreement. This proof might be needed by users and regularities/authorities involved depending on the application scenario. In this demo, we demonstrate our effort to provide for partition-aware atomic commit protocols for transactional data-based agreement.
