On Efficient Topologies for Bluetooth Scatternets

In this paper we investigate the relationship between network capacity and topology for Bluetooth scatternets. We start by considering the intrinsic capacity limits of a scatternet structure, and we show that limiting capacity may be achieved for very local traffic and under specific conditions on the scatternet structure. Then, we provide a description of the performance achievable with two basic scatternet configurations, namely star and closed–loop topologies, and show the role played by inter–piconet interference in the choice of efficient configurations. Finally, we present some efficient topologies, based on Platonic solids structure.
