This article presents a future-driven routing architecture for Internet of Things (IoT). This IoT is a novel concept involving a new concept regarding a set of things with the same routing and service polices, denoted by an autonomous system of things (ASoT). In IoT, an ASoT would be connected not only to the others but legacy autonomous systems (ASs) for the Internet in a wide variety of scenarios. Hence, this article firstly addresses classification of diverse features of ASoTs, and then explores new challenges especially on inter-domain routing
