Introduction to Interoperability for Heterogeneous IoT Platforms

INTER-IoT presents a novel layer-oriented solution for interoperability, to provide interoperability at any layer and across layers among different IoT systems and platforms. Contrary to a more general global approach, the INTER-IoT layered approach has a higher potential in order to provide interoperability. It facilitates a tight bidirectional integration, higher performance, complete modularity, high adaptability and flexibility, and presents increased reliability. This layer-oriented solution is achieved through INTER-LAYER, several interoperability solutions dedicated to specific layers. Each interoperability infrastructure layer has a strong coupling with adjacent layers and provides an interface. Interfaces will be controlled by a meta-level framework to provide global interoperability. Every interoperability mechanism can be accessed through an API. The interoperability infrastructure layers can communicate and interoperate through the interfaces. This cross-layering allows to achieve a deeper and more complete integration.
