W Internet pipeline communication protocol routing algorithm based on content

Abstract

The invention relates to Internet-of-Things communication protocol routing algorithms, in particular to a W Internet pipeline communication protocol routing algorithm based on content. The W Internet pipeline communication protocol routing algorithm based on the content is characterized in that messages can be distributed in a routing mode through message distribution trees according to the covering relation between message content and subscription conditions, dynamic joining and exiting of nodes can be achieved, and failure nodes can be processed. The method includes the steps that (1) a filter model of a multilevel index structure is established, and a fundamental basis is provided for judging the covering relation; (2) subscription trees are established according to the covering relation between the subscription conditions; (3) virtual message distribution trees are established according to the subscription trees and routing tables; (4) messages are distributed along the message distribution trees from top to bottom; (5) when nodes join and exit out of the W Internet and the failures nodes are processed, the message distribution trees are adjusted, and a route is reconstructed. Serving as a common transport protocol of the entire W Internet, the W Internet pipeline communication protocol routing algorithm based on the content enables the protocol to have real-time performance, privacy and high efficiency on data transmission, and load balancing of the entire W Internet is realized.

Description

technical field [0001] The invention relates to a routing algorithm of a communication protocol of the Internet of Things. Background technique [0002] After the emergence of the Internet of Things technology, it has also received high attention in various fields. Many demonstration applications of the Internet of Things have been proposed and constructed, and certain results have been achieved. But at the same time, we can also see that the current development of the Internet of Things has similar characteristics to the electronic network before the Internet, especially "vertical integration" and "proprietary protocols". Many current IoT systems are built to address the specific needs of a certain field or region and are independent of each other. The development of the "Internet of Things" connected by "things-machines" into an "open network" connecting many "Internets of Things" should be the development trend of the Internet of Things. Based on this trend and demand, t...
