Bluetooth, scatternets, topology, network_formation.
A multi-hop ad-hoc network can be formed out of Bluetooth capable devices through the use of scatternets. Many topologies can be deployed for scatternets; the most commonly proposed topology in the literature being a tree. We propose the use of a ring structure for a Bluetooth scatternet. We provide qualitative arguments that describe the advantages of using a ring structure in terms of its added reliability, ease of packet routing and low scatternet scheduling overheads. We then present quantitative results that compare the expected traffic performance of a Bluetooth ring (BlueRing) scatternet against a representative Bluetooth tree scatternet. Finally, we also describe and evaluate two distributed algorithms that can be used to form a BlueRing scatternet out of Bluetooth devices.
