Power-aware IoT based Smart Health Monitoring using Wireless Body Area Network

In Internet of Things (IoT), large amount of data are processed and communicated through different wireless sensor network technologies. For smart health-care application, Wireless Body Area Network (WBAN) which is based on IoT can connect wearable devices to monitor different biomedical signals. In order to ensure continuous monitoring of health over a long period of time in WBAN, power management is a key requirement. A power management technique for prolong and continuous ECG monitoring based on critical data and energy level of battery is proposed in this paper. To reduce the power consumption, a light-weight power management controller is introduced based on the present status of ECG data and battery. The proposed architecture saves up to 27% power consumption in WBAN compared to the conventional architecture without incurring significant overhead.
