A distributed Dual-Ring Tree algorithm for Bluetooth networks
Chih‐Min Yu, Meng‐Lin Ku, En-Li Lin · 2017
In this paper, a distributed Dual-Ring Tree scatternet formation is proposed to generate a reliable topology for Bluetooth networks. To mitigate the formation complexity, each root distributively connects with its downstream roots with local topology instead of global nodes information, instructs them to connect together, and generates a desired dual-ring subnet via distributed computation with three predefined parameters c, r1 and r2. Each root then serves as a coordinator to construct its own spanning tree subnet, finally creating a reliable Dual-Ring Tree scatternet. Computer simulation shows that the distributed Dual-Ring Tree method outperforms the conventional BlueHRT in throughput performance for Bluetooth multi-hop networks.
