Bluetooth Scatternet Tree Formation for Wireless Sensor Networks
Wireless sensor and actor networks based on Bluetooth technology require an algorithm to build up and maintain a Bluetooth scatternet. Although much research has been done, actual deployment is rare because a self-organizing and self-healing procedure suitable for actual Bluetooth nodes has not yet been developed. The authors present the SFX algorithm to build a scatternet tree with the required properties. The method was verified by simulations for up to 400 nodes and by field tests.
