An On-Demand Bluetooth Scatternet Formation Algorithm

In this paper, we propose the On-Demand Bluetooth scatternet formation algorithm (ODBT). ODBT characterizes an ad hoc infrastructure with a tree topology. It is able to cope with topology changes due to either leaving or moving Bluetooth devices, as well as with devices that dynamically join the scatternet. It can support out-of-range devices. We describe in detail how ODBT can be implemented in the Bluetooth protocol stack, and we analyze its performance in comparison with other proposals existing in the literature, also by means of simulation technique
