Abstract

The wireless sensor network (WSN) has limited bandwidth, low power consumption, and may have redundantly collected data. The effective compression of data to reduce the energy consumption in transmission is of great importance. To this end, we proposed a new data-compression algorithm for WSN. The key idea of the algorithm is based on an adaptive threshold and piecewise linear fitting. The adaptive threshold is automatically adjusted by error after the fitting model was applied to the rationality of the adjusted model; subsequently linear fitting is used to determine the reasonable range of subsection based on the detection of continuous unfitting points. From the simulation results, the algorithm is realized in low time complex but with a good data compression effect, and then has a potential practicability.
