In this paper we investigate the relationship between capacity and network topology for Bluetooth scatternets. We start by considering the intrinsic capacity limits of a scatternet structure, and we show that capacity may be approached in the presence of very local traffic only and under specific conditions on the scatternet structure. A worst case analysis is presented, addressing the performance of various network configurations in the presence of a uniform end-to-end traffic matrix. In particular, some efficient configurations, based on Platonic solids, are introduced and analyzed. Finally, we focus on the closed loop configuration, for which algorithms able to improve scatternet performance by exploiting traffic locality are presented and discussed. © 2005 Elsevier B.V.

Abstract
In this paper we investigate the relationship between capacity and network topology for Bluetooth scatternets. We start by considering the intrinsic capacity limits of a scatternet structure, and we show that capacity may be approached in the presence of very local traffic only and under specific conditions on the scatternet structure. A worst case analysis is presented, addressing the performance of various network configurations in the presence of a uniform end-to-end traffic matrix. In particular, some efficient configurations, based on Platonic solids, are introduced and analyzed. Finally, we focus on the closed loop configuration, for which algorithms able to improve scatternet performance by exploiting traffic locality are presented and discussed. © 2005 Elsevier B.V.
