Emerging technologies enable massive deployment of wireless sensor networks across many industries. Internet of Things devices are often deployed in critical infrastructure or health monitoring and require fast reaction time, reasonable accuracy, and high energy efficiency. In this work we introduce a lossy compression method for time-series data, named Direct Lightweight Temporal Compression (DLTC), enabling energy-efficient data transfer for power-restricted devices. Our method is based on the Lightweight Temporal Compression (LTC) method, targeting further reconstruction error minimization and complexity reduction. This work highlights the key advantages of the proposed method and evaluates the method's performance on several sensor-based, time-series data types. We prove that DLTC outperforms the considered benchmark methods in compression efficiency at the same reconstruction error level.
