The invention discloses a dynamic self-networking protocol system and method for the Internet of Things and industrial intelligence. A dynamic network is used to generate a tree protocol to carry out self-networking on the network, so that the whole network can implement networking rapidly under the movement condition, and the problems in sensor node arrangement and networking are solved. The quality of data paths is monitored at any time in the network, the communication quality of the paths in the network are compared, and thus, the transmission quality of the whole network is highest.
