Performance of adaptive bridge scheduling in a scatternet with a slave-slave bridge
End-to-end packet delays in a Bluetooth scatternet with a Slave-Slave (SS) bridge can be minimized by adjusting the bridge residence times in accordance with traffic intensity and locality. This paper presents two algorithms to do so. One of these uses a fixed value of the bridge residence time, while the other adjusts the residence time dynamically according to the instantaneous intensity of inter-piconet traffic. We discuss the performance of these algorithms and show that the adaptive algorithm offers better performance than the fixed residence time one, provided the parameters are chosen appropriately. We also consider the stability of both algorithms and show that they have comparable stability limits. Copyright (C) 2004 John Wiley Sons, Ltd.
