As intelligent IoT develops, large amounts of data are required, and the use of wireless sensor networks that can efficiently collect large amounts of data is increasing. As a method of increasing the lifespan of sensor nodes in wireless sensor networks, harvesting energy from the surrounding environment or directly transferring energy through wireless power transmission are used. In this environment, it is important to save energy and increase the lifespan of the sensor node, but it is also important to use the remaining energy efficiently. In this paper, we propose a technique to increase the data transmission success rate in a limited data collection amount by transmitting duplicate data using the remaining energy when each sensor node has energy remaining in a wireless sensor network. In this technique, the energy remaining after transmitting data is calculated in advance, and this is used to determine the amount of duplicated data transmission. Simulation results show that this technique collects more data by lowering the packet error rate compared to other existing techniques.
