ABSTRACT
Bluetooth Low Energy (BLE) is a representative wireless technology for Internet of Things (IoT) that enables concurrent communication with multiple devices at low power. However, the connection establishment mechanism of BLE is susceptible to resource overlap problem among connected peripherals, leading to resource unfairness. To address problem and improve resource utilization, we propose a "Subrating-based Connection Scheduling (SCS)". It schedules and periodically manages connections by considering the service requirements of the connected devices. Preliminary experiments demonstrate that SCS achieves higher throughput and fairness compared to popular commercial BLE stacks while satisfying the requirements of peripherals.
