Mapping model of multi-identifers oriented to Internet of Things
Ping Wang · Scientia Sinica Informationis · 2013
Although in the course of messages transport of the perception data, there are many diferent methods of identifers information on the Internet of Things(IOT), a strict mapping mechanism is missed which leads to many difculties in tracing information and controlling devices, further undermining IOT services opening. On the basis of four layer model of IOT, this paper comprehensively analyzes the marking methods of information in each layer, and proposes a new mapping model of diversifed identifers on IOT in heterogeneous network structures.In light of the whole processing of information on IOT, we focus on analyzing the identifers mapping methods of information in adopting, transmission, processing and displaying and establishes new mapping methods to identify the information identifers from origin devices and IPv6 address, meta data and resource identifers,resource identifers and resource catalogue identifers. By building a diversifed identifers mapping model, we gain a better identifcation and control of metadata and can retrace the information source under IOT services.Finally, the author verifed the feasibility through the prototype of smart campus.
