Topology-controllable scatternet formation method and its implementation

This paper proposes a method to form a Bluetooth scatternet under the conference scenario. The principles and formulas for calculating network topologies are discussed in detail. The method is proved by implementation using commercially available Bluetooth devices. The scatternet topology can be star, mesh, ring and linked line, which is controlled by changing parameters like the number of maximum slaves in a piconet, the number of maximum piconets that a gateway Bluetooth device can participate, and whether loops are needed in the resulting scatternet. In this paper, we also present a lot of testing results from forming the real scatternet.
