Bluetooth is a short range wireless communication technology, which is widely used in our daily life, In-Vehicle Communication, industrial control and so on. All above these applications need multiple Bluetooth devices to communicate with each other. So controlling different Bluetooth devices access channels to achieve efficient data transmission has become a hotspot of Bluetooth communication. With the increasingly wide use of IoT (Internet of Things) and IoV (Internet of Vehicles), the transmission of real-time business between Bluetooth devices will be ubiquitous. How to make the main equipment fair and timely schedule services from the device is the key to scheduling algorithm. In this paper , in order to solve the problems of efficiency, fairness, real-time service and non-real-time service coexistence, proposes a dynamic bandwidth allocation algorithm in Bluetooth piconet based on multipriority, dividing business into multiple priorities and implemented a fair and efficient scheduling algorithm to guarantee the Qos demand of different types of business.
