AI Technical Summary

Technical Problem

In complex multi-intermediate node IoT scenarios, the prior art is difficult to effectively solve the problem of multiple forwarding in data transmission, resulting in increased transmission delay and waste of frequency resources.

Method used

An intermediate node selection method is provided. By obtaining the node selection result of the terminal device, a candidate intermediate node is determined, and a reselected intermediate node is selected according to the communication quality parameters, the terminal device is controlled to disconnect the communication connection of the primary intermediate node, and establish a communication connection with the reselected intermediate node.

Benefits of technology

The accuracy of intermediate node selection is optimized, data transmission delay is reduced, network efficiency and reliability are improved, and excessive occupation or waste of frequency resources is avoided.

Abstract

The invention relates to the technical field of Internet of Things, in particular to an intermediate node selection method and device and read-write equipment. The method comprises the following steps: acquiring a node selection result of the terminal equipment; the node selection result comprises a primary selection intermediate node selected by the terminal equipment in an intermediate node set based on a local selection strategy; under the condition that the node selection result of the terminal equipment meets the node reselection condition, determining at least one candidate intermediate node corresponding to the terminal equipment; wherein the candidate intermediate node can communicate with the terminal equipment; selecting a reselected intermediate node corresponding to the terminal device from each candidate intermediate node according to a communication quality parameter between the terminal device and each candidate intermediate node of the terminal device; and controlling the terminal equipment to disconnect the communication connection with the primary selection intermediate node, and establishing the communication connection with the reselection intermediate node.
