BlueHRT: Hybrid Ring Tree Scatternet Formation in Bluetooth Networks

Bluetooth wireless technology is being installed in almost any electronic or information device for ad-hoc connectivity among them. Up to eight Bluetooth devices can form a network called a piconet. Interconnecting multiple piconets through gateway devices forms a scatternet. In the Bluetooth specifications, no scatternet topology has been specified. This paper proposes a scatternet formation topology that, unlike the existing literature, considers the non-uniform distribution of Bluetooth devices. Our proposed approach dictates a ring topology formed in the dense area and extended by trees to the other areas. The proposed approach is denoted as BlueHRT: Hybrid Ring Tree Scatternet Formation in Bluetooth Networks. Results are presented to highlight the performance gains of the proposed approach.
