An adaptive power-conserving service discipline for bluetooth (APCB) wireless networks

Research output: Contribution to journalArticlepeer-review


Bluetooth is a new short-range radio technology to form a small wireless system. In most of the current bluetooth products, the master polls the slaves in a round robin (RR) manner and it may waste a significant amount of power. Many solutions were proposed to reduce the power consumption of the slaves. However, these solutions cannot achieve a good balance between the power consumption and QoS provision. We propose an adaptive power-conserving scheme to address this problem. The proposed solution schedules each flow based on its predictive rate and achieves power optimization based on a low-power mode existing in the bluetooth standard. Unlike other research work related to low-power, we also consider QoS provision for each flow. Theoretical analyses verify that our scheme can achieve throughput guarantees, delay guarantees, and fairness guarantees. Simulation results demonstrate that our scheme outperforms the RR scheme and other existing works in terms of significant power saving and good QoS provision. It also shows that there exists a tradeoff between power and delay under varies traffic models.
