Interoperability of device identification in heterogeneous IoT platforms

In order to build a smart home environment using IoT (Internet of Things) technology, up to now the IoT devices (e.g., smart door locks, smart home retrofit, connected smart kitchen, etc.) should have same device identification (ID) system based on a single IoT platform. That is, it is difficult to identify the device ID operated in different IoT platforms (e.g., oneM2M, GS1, IBM Watson IoT etc.) because each IoT platform uses a different device ID system. Moreover, despite the considerable research relating to interoperability between heterogeneous IoT platforms, little attention has focused on device ID interoperability in diverse IoT platforms. Therefore, in this paper, in order to overcome this problem, we analyze the existing device ID systems and propose the conceptual model of IoT device ID translator, named IoT DNS (Device Name System), which can translate diverse types of device ID into oneM2M device ID format.
