Enabling Transparent Communication with Global ID for the Internet of Things

Enabling the Internet of Things (IoT) requires a global identification system for things to be distinguished from trillions of things and to make them globally accessible from the Internet. Unfortunately, the current Internet architecture using an IP address as both ID and locator (i.e., address) makes it difficult to improve networking solutions for the IoT. To solve this, we newly design novel IoT architecture composed of Things' Identification Service (TIDS) and Things' Profile Service (TPS), enabling things to use both a domain name and a global ID in globally accessing other things in the world. It also exploits existing Domain Name Service (DNS) and Dynamic DNS (DDNS) to trace of mobile thing's changing IP address. In addition to this, we develop Things' Application-level Protocol (TALP) to provide users with transparent access to the things over heterogeneous networks. To show the feasibility, we implement TIDS, TPS, and TALP and construct the test-bed for the proposed IoT architecture. Based on this, we prove the feasibility of the proposed IoT architecture.
