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

Abstract

The invention provides a hierarchical Chord packet network and an organization method thereof in Internet of things. The organization method comprises the following steps of: constructing two levels of networks, wherein the first level of network is constructed as a Chord network and consists of supernodes of each packet on the basis of a distributed hash table, and the second level of network isconstructed as subnetworks independently consisting of each packet, wherein each packet is in charge of object name service of one organization, and the first level of network and the second level ofnetwork are associated through a supernode group of each pocket. The packet network organization method which is flexible and is expandable in scale is more suitable for a pocketed bottom-layer actual network, thereby improving the name inquiry efficiency in the pocket.

Description

technical field [0001] The present invention relates to the technical field of object name service in the Internet of Things, and more specifically, the present invention relates to a hierarchical Chord grouping network in the Internet of Things and its organization method. 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...
