Identity (ID)-based unified identification method for sensing layer equipment on network layer

Abstract

The invention belongs to the technical field of network communication, relates to the internet of things, in particular to an identity (ID)-based unified identification method for sensing layer equipment on a network layer. The unified identification method is characterized by comprising the following steps of: adding an equipment management layer between a sensing layer and the network layer; mapping the ID of the sensing layer equipment to the equipment management M-ID of the equipment management layer according to a certain rule, wherein the equipment management M-ID of the equipment management layer is used for identifying the expression, the identification and the management of the sensing layer equipment on the equipment management layer and the network layer; and on the basis of the identification, realizing the information conversion, transmission and exchange between the sensing layer and the network layer, and realizing the unified expression and identification of the numerical value and the state information of the sensing layer equipment on the network layer. The unified identification method has the advantages that the problems of expressing and identifying the sensing layer equipment on the network layer in the current internet of things and the problem of transmitting the information of the sensing layer equipment on the internet-based network layer are solved; the technical principle is simple; the using cost is low; and the market prospect is broad.

Description

technical field [0001] The invention relates to the Internet of Things and belongs to the technical field of network communication, in particular to an ID-based unified identification method for perception layer devices at the network layer. Background technique [0002] The International Telecommunication Union (ITU) pointed out in a concept document related to the Internet of Things that the goal of information and communication technology has developed from connecting anyone at any time and anywhere to the stage of connecting any object, and the connection of everything forms the Internet of Things. Networking (the internet of things). [0003] The Internet of Things is an information system composed of perception layer, network layer and application layer. Since the concept of the Internet of Things is broad and involves many fields, it determines the diversity of the application layer and the perception layer. However, from the perspective of deployment, the system ca...

AI Technical Summary

Problems solved by technology

However, transmitting the perception layer information in the local area network through the Internet still faces many problems, such as the problem of IPv4 addresses, the problem of high user cost, etc., which have become important factors restricting the development of the entire Internet of Things industry.
