Abstract
Bluetooth Low Energy (BLE) is a popular technol-ogy in Internet of Things (IoT). Bluetooth Core Specification v5.2 provides a new Bluetooth audio transmission technology - BLE Audio. BLE Audio provides two transmission modes - connection oriented Connected Isochronous Group (CIG) and broadcast oriented Broadcast Isochronous Group (BIG). In this paper, we design a QoS (Quality of Service) sensitive networking scheme based on BLE Audio (QSNBA). First, a layered architecture based on BLE Audio is proposed. Then, we use defined broadcast packets for information exchange to form the master-slave node cluster. Next, according to time delay, reliability and other parameters, multi-hierarchical fuzzy comprehensive appraisal (MFCA) is used to select the appropriate mode between master and slave nodes in the two transmission…
