A novel dynamic priority round robin polling scheme for Bluetooth piconet

摘要

According to the latest Bluetooth specifications, the communications between slave devices within a piconet are controlled by the master node in which the master device must participate in all the information exchange activities. Consequently, how to design a polling scheme which can obviously reduce average packet delay and improve bandwidth utilization is an important issue. In this paper, we propose a traffic history based Dynamic Priority Round Robin (DPRR) polling scheme to improve the efficiency of Bluetooth piconet. As expected, the simulation results show that the proposed polling scheme can achieve a low packet delay and high bandwidth utilization.
