Energy Modeling Based on Power Profiling of Wireless Sensor Device

This article elaborates on an accurate energy model (EM) for wireless sensor devices (WSDs) based power consumption measurement. A deep understanding of WSD’s cost depends the functional components contributing to communication process. The includes different stages transmission (Tx) and reception (Rx) modes. practical EM is developed with data packet lengths, rate, operation status, predesigned versus appropriate bus, mode, including mutual transfers between microcontroller radio module. validity verified through experimental setup having a TelosB device. As expected, modeled measured consumed by WSD operating from 1-to-4-MHz CPU frequencies 2-to-100-byte payload in very good agreement. It was found that, compared processing, Tx, listening, Rx phases, transfer consumes up 40% total energy, whereas this aspect often neglected usual models. Overall, proposed provides significant accuracy might be helpful improving efficiency future networks.
