A Study on DRX Mechanism for Wireless Powered LTE-Enabled IoT devices

Long Term Evolution (LTE) networks enabled Internet of Things (IoT) devices are characterized by limited lifetime since they are battery powered and power hungry services. Recently, researchers have come up with Wireless Power Charging (WPC) mechanism that harvest energy from received radio frequency power for extending battery lifetime of IoT devices. However, existing Discontinous Reception (DRX) mechanism is not tailored for the advantages of WPC and configure the DRX based on limited battery energies and WPC. Therefore, in this paper, we propose mathematical model and analysis of the DRX mechanism of LTE-enabled IoT devices based on fixed WPC.
