碩士 === 國立中正大學 === 資訊工程研究所 === 92 === The quality-of-service (QoS) communication that supports mobile applications to guarantee the bandwidth utilization is an important issue in Bluetooth WPANs. In this thesis, we address the problem of on-demand QoS routing with interpiconet scheduling in Bluetooth WPANs. A credit-based QoS (CQ) routing protocol is developed with the consideration of different Bluetooth packet types because that Bluetooth packets with different types have different bandwidth utilization. This work improves the bandwidth utilization in the Bluetooth scatternets by providing a new interpiconet scheduling scheme. Centralized and distributed algorithms are investigated in this work to improve the bandwidth utilization for the on-demand QoS routing protocol. The performance analysis illustrates that our credit-based QoS routing protocol has the performance achievements, compared to existing QoS routing protocols.
