An OID-based identifier framework supporting the interoperability of heterogeneous identifiers

The Interoperability of heterogeneous identifiers is rising as a main prerequisite to realize the Internet of Thing (IoT) vision. However, it seems to be a very difficult issue due to the heterogeneity of things in the IoT such as hardware capability, interworking protocol, address schemes, and etc. In the research, the Virtual Identifier Layer (VIL) is proposed to overcome the heterogeneity and to provide the unified identification service. The VIL is a virtual identifier framework constructed over the existing identifier infrastructures using the concept of meta-resolution and metadata repository. It can provide an interoperable resolution between things belonging to heterogeneous identifier infrastructure while letting the existing identifier infrastructures to keep their own territories.
