Abstract
Bluetooth scatternet is a set of piconets interconnected via bridge devices. A good inter-piconet scheduling is necessary for the bridge devices to switch among the piconets they participated. This paper proposes an inter-piconet scheduling algorithm, Traffic-Aware Scatternet Scheduling (TASS), for bridges in bluetooth scatternets. According to the traffic information of all masters that the bridge is connected, TASS can adaptively switch the bridge to the masters with high traffic loads and increase the usage of the bridge. In addition, TASS can reduce the number of failed unsniffs and the overhead of the bridge switch wastes to further increase the overall system performance. Simulation results show that TASS outperforms the existing inter-piconet scheduling in network throughput and adaptability for various traffic loads.
