Abstract
IoT-based maritime monitoring is constrained by excessive power consumption due to raw data transmission on resource-limited devices. This study compares lossy Thresholding data reduction and lossless Gzip compression methods for optimizing firmware transmission in Buoy IoT . Experiments were conducted through data acquisition in open water for 3 hours (5,400 samples, 2-second interval) using a unified firmware running four test scenarios simultaneously on an ESP32 DevKit V1 and a DHT22 sensor. Results show Scenario A (Raw Baseline) produces a 97,084-byte file (RR = 0%) with an execution time of 0 µs and 0 Bytes of memory. Scenario B (Gzip) compresses data to 22,375 Bytes (RR = 76.95%) with a processing time of 272.4 ms per batch and 102 KB of memory. Scenario C (Thresholding) filters data to 10,652 Bytes (RR = 89.03%, latency of 15.0 µs, 8 Bytes of memory). Scenario D (Hybrid) yields the smallest file of 3,432 Bytes (RR = 96.46%) with a latency of 209.1 µs and 20 KB of memory. Due to high data variability, Thresholding yields a higher RR than Gzip. Based on multi-dimensional Trade-off analysis, Scenario C is recommended for standard monitoring due to its optimal balance of efficiency, speed, and RAM safety, while Scenario D is recommended when full data reconstruction is required.
