面向物联网的多元标识映射模型
摘要
Although in the course of messages transport of the perception data, there are many different methods of identifiers information on the Internet of Things (IOT), a strict mapping mechanism is missed which leads to many difficulties 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 diversified identifiers on IOT in heterogeneous network structures. In light of the whole processing of information on IOT, we focus on analyzing the identifiers mapping methods of information in adopting, transmission, processing and displaying and establishes new mapping methods to identify the information identifiers from origin devices and IPv6 address, meta data and resource identifiers, resource identifiers and resource catalogue identifiers. By building a diversified identifiers mapping model, we gain a better identification and control of metadata and can retrace the information source under IOT services. Finally, the author verified the feasibility through the prototype of smart campus.
