Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The data hierarchical transmission method provided by the present invention takes wireless sensor network data transmission as an example, but it is not limited thereto. The present invention can work with any existing wireless sensor network data transmission protocol to jointly complete the collection and transmission of network data Task. Wireless sensor nodes 5 are mainly divided into the following three categories:

[0045] Ordinary node 6: Ordinary node 6 is responsible for collecting data and sending the data to Sink node 1 according to the prescribed method. These nodes have limited energy and limited processing power.

[0046] Cluster head node 2: Ordinary node 6 takes turns to act dynamically. Usually, it is an ordinary node 6 with relatively sufficient energy.

[0047] Sink node 1: It has strong communication and p...

Abstract

The invention provides a data grading transmission method. The method includes the steps that wireless sensor nodes in a network are used for collecting data, the collected data are graded, and the graded data and the collected data are packaged into a data message to be transmitted; the wireless sensor nodes are used for recording sending state information of the transmitted data message; an intermediate node is used for receiving the data message, the graded data are extracted, and the data message is forwarded in different modes according to different grades by combining the communication condition of the current network and the state of the intermediate node itself; information recording is conducted on the forwarded data message by the intermediate node; all the nodes in the network are used for sending the data message, collecting and forwarding the data message through a data transmission protocol of the network where the nodes are placed until the network stops working.

Description

technical field [0001] The present invention relates to the application field of wireless sensor network data transmission technology, and specifically relates to the use of classification to solve the problem of generating a large amount of data in the process of wireless sensor network data collection and transmission, reducing redundant data to improve data transmission efficiency and reduce network bandwidth consumption , A data hierarchical transmission method that reduces the number of wireless data transmission collisions and saves node energy. Background technique [0002] A wireless sensor network is a network formed by a large number of deployed sensor nodes with sensing, processing and wireless communication capabilities through self-organization, and plays a role in sensing data in the Internet of Things. Wireless sensor networks are widely used and can be widely used in military, environmental monitoring, urban transportation, warehouse management, health monito...
