Methods for Reducing the Amount of Data Transmitted and Stored in IoT Systems
In this paper presented method for reducing the amount of data transmitted and stored in IoT systems. Instead of expensive and complex network devices, developers can use cheap and proven low-speed solutions (ZigBee, NB IoT, BLE). This approach focuses on sensor processing. Correlation and autocorrelation methods for event detection depending on waveform are described in detail and implementation of endpoint architecture is proposed. Novelty and another feature of this approach is the use of not the full waveform, but their components and processing on the device. This significantly reduces the number of operations and complexity of implementation. Other methods focus on the cloud computing paradigm. The results of the simulation show that at the data transfer rate from the sensor ~10 MSample/s, the proposed method allows you to transmit and store 280 bytes in 70 min instead of 157 GB using the bypass method. Reducing data transfer and storage requirements will simplify and reduce the cost of IoT systems, improve performance, and apply additional precision sensors to provide more accurate data.
The solutions are focused on low-power and FPGA/ASIC implementations.
