Comparative study of compression algorithms on time series data for IoT devices
(2019) EITM01 20191Department of Electrical and Information Technology
- Abstract
- This Master’s thesis evaluates the performance of lightweight compression algorithm
aimed for IoT sensor devices. These devices are most often battery driven
and produce large amounts of sensor data which is sent wirelessly. Compressing the
data could be a tool in decreasing the power usage of these devices. The algorithms
were evaluated based on their compression ratio, memory consumption and CPU
usage. The results showed that the algorithms DRH, improved RLBE and A-LZSS
performed the best according to different criteria. DRH gave the most balanced
performance on all metrics, while improved RLBE is aimed towards datasets with
steeper changes, and A-LZSS towards datasets with reoccurring sequences.
