摘要

This paper presents COMPOSE, an open-source Platform as a Service (PaaS) for developing Smart City solutions based on connected objects. COMPOSE is built around open-source components that allow storing, streaming and processing of sensor data, communication with connected objects using M2M protocols, service discovery, data provenance and multi-tenancy, deployment and scalable hosting of applications in a cloud environment, workflow editing and cross-platform smartphone application development. A use case developed for deployment in the city of Barcelona that utilizes the aforementioned components among with parking and traffic sensors is also presented.
