A Scheduling Algorithm with Guaranteed Bandwidth Services for Bluetooth Scatternets

Each Bluetooth device has different traffic loads and bandwidth requirements for various applications. In order to provide time-bounded and QoS-sensitive services with effective performance, this paper proposes a scheduling algorithm adopting a resource reservation scheme that provides bandwidth guarantee to meet various end-to-end bandwidth requirements in scatternets. A coordination scheme is also proposed to efficiently manage guaranteed bandwidth services. In experiments, ns-2 simulator is used to demonstrate the QoS guarantee of the guaranteed bandwidth service.
