Abstract
Smart cities are becoming a vibrant application domain for a number of science fields. As such, service providers and stakeholders are beginning to integrate co-creation aspects into current implementations to shape the future smart city solutions. In this context, holistic solutions are required to test such aspects in real city-scale Internet of Things (IoT) deployments, considering the complex city ecosystems. In this paper, we discuss OrganiCity’s implementation of an experimentation-as-a-service (EaaS) framework, presenting a toolset that allows developing, deploying, and evaluating smart city solutions in a one-stop shop manner. This is the first time such an integrated toolset is offered in the context of a large-scale IoT infrastructure, which spans across multiple European cities. We discuss the design and implementation of the toolset, presenting our view on what EaaS should provide, and how it is implemented. We present initial feedback from 25 experimenter teams that have utilized this toolset in the OrganiCity project, along with a discussion on two detailed actual use cases to validate our approach. Learnings from all experiments are discussed as well as architectural considerations for platform scaling. Our feedback from experimenters indicates that EaaS is a viable and useful approach.

We discussed the implementation of an EaaS framework within OrganiCity, and have presented our position regarding EaaS, i.e., to use existing IoT deployments in multiple cities in a federated manner to implement smart city prototype solutions
We have presented our design and implementation, discussed how OrganiCity and its toolset fit into the current smart city landscape, and presented several core components
Summary
In terms of experimentation testbeds, SmartSantander [11] built one of the largest city-scale IoT research infrastructures, pioneering the experimentation of novel smart city architectures, services, and applications in real-world urban environments. It emphasized managing experiments at an IoT device level, while allowing data-acquiring tasks facilitating urban services on top of the captured data flows. Synchronicity features open calls for developing new services, similar to OC, but places a much larger focus on open data markets in the context of a smart city, leaving aside the co-creative approach.
