A data receiving method and device based on clustering structure wireless sensor network

Abstract

The invention discloses a data receiving method and device based on a clustering structure wireless sensor network. The method and the device are applied to the clustering structure wireless sensor network. Prediction and approximation are carried out on data collected by nodes through utilization of a prediction model, and energy consumption of node devices is reduced by suppressing node data transmission. According to the scheme, on the premise of satisfying application demands, the in-network data transmission quantity can be effectively reduced, the energy consumption of the nodes can be reduced, and a life cycle of the network is improved.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data receiving method and device for a wireless sensor network. Background technique [0002] At present, wireless sensor network (WSN) has been widely used in smart home, agricultural planting, environmental monitoring and chemical production and other fields. [0003] A wireless sensor network (WSN) is an ad hoc network composed of a large number of spatially discrete sensor nodes through wireless communication, such as figure 1 Shown is a schematic diagram of the structure of a traditional wireless sensor network system. Wherein, the task management node is connected with the sink node through the communication network, and wireless communication is performed between the sink node and the sensor nodes in the target monitoring area. [0004] Each sensor node cooperates with each other to perceive, collect, process and transmit various target information in the are...

AI Technical Summary

Problems solved by technology

There is often a correlation between the data collected by densely distributed nodes, resulting in redundancy of some related data, and the data collected by the same node periodically according to time also has certain redundancy, which makes the data transmission energy high and causes network problems. waste of resources

[0011] Therefore, there is an urgent need for a technology that uses a clustered routing structure to solve the problems of redundancy and high energy consumption in data transmission during data transmission.
