CONTENT-BASED W INTERNET CHANNEL COMMUNICATION PROTOCOL ROUTING ALGORITHM

摘要

The present invention relates to a routing algorithm for an internet-of-things communication protocol. A content-based W Internet channel communication protocol routing algorithm; on the basis of the covering relationship between message content and subscription conditions, routing and distributing a message according to a message distribution tree; dynamic joining and dropping of a node, and faulty node processing are supported. The method is: 1) establishing a filter model of a multi-level index structure in order to provide a theoretical basis for determining a covering relationship; 2) on the basis of the covering relationship between subscription conditions, establishing a subscription tree; 3) on the basis of the subscription conditions and a routing table, constructing a virtual message distribution tree; 4) messages are distributed along the message distribution tree from top to bottom; 5) when a node joins or drops a W Internet network, and when processing a faulty node, adjusting the message distribution tree, and re-constructing routing. As a common transfer protocol for the whole W Internet, the present invention allows the protocol to have real-time performance, privacy, and effectiveness for data transfer and achieves load balancing for the whole W Internet.
