The invention discloses a data transmission method and device, and the method comprises the steps: generating RTS information of a high-priority data package when a source node transmits the high-priority data package, and broadcasting the RTS information; when the source node receives CTS1 information broadcasted by the RTS receiving node based on the RTS information, sending the high-priority data packet to the RTS receiving node from the source node; when the RTS receiving node receives CTS2 information sent by the CTS receiving node, sending the high-priority data packet to the CTS receiving node from the RTS receiving node. According to the invention, when the high-priority data packet is transmitted, the high-priority data packet is transmitted along the node on the high-priority data transmission path, so that the important data packet is effectively transmitted in time. In addition, only the corresponding node can respond to and return information according to a request sendingmessage or a request clearing message sent by the node, so that data loss caused by data sending conflicts is avoided.
Description
technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission method and device. Background technique [0002] The Internet of Things has the advantages of low energy consumption, low cost, high flexibility, and scalability, and can be widely used in many fields such as national defense and military, agricultural monitoring and control, environmental monitoring and forecasting, smart homes, and medical care. The main network of the Internet of Things is a sensor network composed of a large number of tiny and cheap sensor nodes deployed in or near the monitoring area through self-organization. [0003] figure 1 It is a network system architecture diagram of the Internet of Things. The Internet of Things network system usually includes a sensor node (sensornode), a sink node (sink node) and a task management node. A large number of sensor nodes are randomly deployed in or near the monitoring area, and ...
