With 14 partners, the project aims to provide an experimental infrastructure for enabling IoT testbed/platforms operators to interconnect their facilities in an interoperable way based on the European FIRE testbeds. Furthermore, FIESTA is going to facilitate researchers and solution providers to design and deploy large scale integrated applications that transcend the (silo) boundaries of individual IoT platforms or testbeds. The OpenMTC team at FOKUS is going to bring the OpenMTC into such federated infrastructure as an integral element of the FUSECO Playground.
