Research on dynamic bandwidth allocation algorithm in bluetooth piconet based on multipriority

Bluetooth is a short range wireless communication technology, which is widely used in our daily life, In-Vehicle Communication, industrial control and so on. 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.
