Abstract

The invention relates to the technical field of data compression of wireless sensor network nodes, in particular relating to a data compression method of wireless sensor network nodes based on non-threshold. The method in the invention can perform effective segmental broken line compression on time series data streams collected by the wireless sensor network nodes in a period of time under the premise of ensuring the data compression ratio or data reconstruction precision required by users, thus lowering energy consumption of the sensor nodes and delaying the network life cycle. As the invention is based on the characteristic of the non-threshold, users can perform effective compression on data without possessing any future knowledge about a monitored object, thus being applicable to compression of various time series data with different fluctuation characteristics and being widely used for compression of data of the wireless sensor network nodes needing long-term monitoring.
