Object name resolution system and method in internet of things

Abstract

The invention provides an object name resolution system and method in the internet of things. The method comprises: a normal node sends an object query name resolution request to a super node in a vector group corresponding to the super node; the super node determines the grouping of the second level of Chord in the first level of Chord according to the identification code of manufacturers; the super node inquires a URL (uniform resource locator) corresponding to the product identification code in the grouping; and a destination node corresponding to the URL returns the object name service address to users. The first level of Chord is the network constituted by the super node groups of each grouping based on a distributed hash table; the second level of Chord is constituted by each grouping, and each grouping is responsible for the object name service of an organization; and the first level of Chord and the second level of Chord are interconnected through the super node group in each grouping. The object name resolution system in the invention can be used for solving the problems of performance bottleneck in existing high levels, low ability in resisting attacks, frequent configuration errors and unbalanced loading and the like, and supporting multiple encoding methods.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things object name service, and more specifically, relates to an object name resolution system and a resolution method thereof in the Internet of Things. Background technique [0002] In the Internet of Things technology, the object name resolution service is used to map the object name to the information service address (IS URL) provided by the item manufacturer to provide users with relevant information about the item. [0003] The object name resolution service technology of the Internet of Things is applied to the ONS (Object Naming Service, Object Name Service) system of the existing EPC (Electronic Product Code, product electronic code, which provides a unique identifier for objects in the physical world), and the ONS system integrates the EPC The code is mapped to one or more URLs (Uniform Resource Locators), through which detailed information about the product on the EPC IS ser...

AI Technical Summary

Problems solved by technology

[0005] In short, the existing methods use a hierarchical tree structure similar to DNS to realize the object name service in the Internet of Things. This structure does not support multiple encoding methods, and there are high-level performance bottlenecks, weak anti-attack, frequent configuration errors and load. unbalanced problem
