A Lossless Data Compression Algorithm for Wireless Sensor Networks Based on Linear Regression Model
Hong Zhi Lu, Xue Jun Ren · Advanced materials research · 2011
According to the theory of simple linear regression model, this paper designed a lossless sensor data compression algorithm based on one-dimensional linear regression model. The algorithm computes the linear fitting values of sensor data’s differences and fitting residuals, which are input to a normal distribution entropy encoder to perform compression. Compared with two typical lossless compression algorithms, the proposed algorithm indicated better compression ratios.
