ABSTRACT
The Internet of Things (IoT)-EPI efforts towards providing a framework for IoT platforms interoperability have already provided new advanced IoT platforms interoperability mechanisms and approaches. IoT environments are rather complex with heterogeneous physical devices supporting various communication protocols, while they are possibly connected to an intermediary gateway and then to their virtual representations running on different platforms. IoT platforms require interoperability on multiple levels, which means finding the characteristic functionalities of each layer and defining meta-protocols that can be mapped on the ones used in the platforms. The most promising aspects of a common framework for IoT interoperability are finding common approaches to resource access, resource discovery as well as semantic interoperability. The IoT research community has to agree on data sets for evaluating IoT platform ingestion performance, as well as agree on sets of real-time queries for evaluating an IoT platform digestion performance.
