Abstract

Bluetooth uses TDD (time division duplex) to arrange the transmission slots so that it can avoid collisions. Bluetooth has a master-slave configuration, called a piconet. The link polling policy adopted by a master may significantly influence the delay and throughput of a piconet. In this paper, we propose an enhanced efficient and QoS (quality of service)-aware MAC (medium access control) scheduling algorithm based on the bandwidth utilization. We consider Bluetooth packets of different type combinations (DHl/DH3/DH5/DMl/DM3/DM5) to be exchanged by a master-slave pair that can properly reflect the traffic of the pair. By selecting a link with high bandwidth efficiencies, the precious wireless bandwidth can be better utilized. Simulation results show that our algorithm demonstrates better performance and can be extended to satisfy QoS requirements of various applications.
