A self-organising protocol for Bluetooth scatternet formation

Abstract

We propose a self-organising protocol for Bluetooth topology construction in which scatternet structures are maintained even in the presence of dynamic perturbation of network configuration. The protocol does not require the presence of a central topology construction or re-construction process. Instead, the nodes can self-organise to create a stable configuration both after start-up as well as after intermediate changes due to the arrival of new nodes or shutting down of existing nodes. The proposed algorithm uses a bottom-up approach, which is built into the regular operations of the Bluetooth devices. Isolated nodes as well as masters and slaves of existing piconets can discover other nodes, thus extending the scatternet. Copyright © 2005 AEIT.
