Abstract
En 中文
IoT devices are gaining more importance as they are involved in solving modern world problems in many industries like health, agriculture, manufacturing and many others. The limited power capability of IoT devices drives the research to find new methods of extending the battery lifetime. In this work, we introduce a new approach that helps in reducing the power consumption driven by the IoT device information. The proposed approach allows the IoT device to send its data to the CoAP (Constrained application protocol) server only if its current reading is different from the old one. We used the Intel Lab Data to conduct experiments using the proposed approach on real-world sensor readings. The experiments have shown that the proposed approach allowed device lifetime extension by 33% to 155% with respect to the standard CoAP protocol and device lifetime extension by 8% and 14% with respect to the dynamic tuning approach.
