Description

technical field [0001] The invention relates to the technical field of data compression, in particular to a sensor data network compression system based on time-space correlation. Background technique [0002] The rapid development of micro-electromechanical systems and wireless communication technology directly promotes the continuous transformation of sensor networks in the direction of low cost, high intelligence, and wireless networking, and greatly enriches the learning resources and learning methods of various wireless sensor network theories. At the same time, the opportunities and challenges brought about by this transformation have also attracted the attention of scholars at home and abroad, which has led to the proposal of a new concept of node energy reduction in wireless sensor networks and the research, discussion and practical application of compression methods based on node-collected data. The sensor network is to deploy a large number of low-power and low-cos...

AI Technical Summary

Problems solved by technology

[0003] At present, when the existing sensor data network data compression system on the market is running, the sensor data is usually directly compressed based on the serial number after transmission, and when the compressed sensor data is retrieved later, the serial number of the serial number is retrieved. Sensing data takes a long time, so it affects the compression and subsequent use of sensory data network data
