Building Efficient Bluetooth Scatternet Topologies from 1-Factors

Simon Baatz, Christoph Bieschke, Matthias Frank, Carmen Kühl, Peter Martini, Christoph Scholz

Abstract:

Bluetooth introduces ad hoc connectivity into the personal area. Although only the basic single-hop star-shaped topology called piconet is currently available, Bluetooth will surely evolve towards multi-hop connectivity in the near future. These multi-hop networks (called scatternets) offer a wide range of possible topologies. In this paper it is argued that the overall efficiency of scatternets heavily depends on the specific network topology employed. Furthermore, we introduce a class of network topologies that are efficient with respect to the aggregate bandwidth possible. A distributed algorithm for automatic network establishment is outlined.
