Recently, the measurement of daily using wearable devices has been attracting attention due to increasing health awareness. The importance of vital data may vary depending on the type of data generated. Daily body temperature or physical activity data are less important, while urgent data such as seizures and falls are more important. By prioritizing data according to their importance, improving the quality of communication of highly important data is necessary. In this paper, we propose a communication scheme that improves on the priority-controlled communication scheme specified as Multi-use Channel Access (MCA) mode in SmartBAN, which is standardized by ETSI and IEC. We also demonstrate the usefulness of the proposed scheme by implementing the SmartBAN scheme and the proposed scheme on actual devices and experimentally evaluating their characteristics.
