摘要：
ith the vigorous development of wireless technology, the life style of human beings has been improved with more convenience and comfort. Bluetooth is a critical technology applied in a shorter distance wireless network. The roles of Bluetooth devices can be divided into three types: master, slave, and bridge. However, the master or bridge nodes become the bottleneck of a data traffic flow. A novel Bluetooth scatternet formation is required to obtain better QoS and lower power consumption. This study presents two novel algorithms. The first is Bluetree++ for increasing scatternet performance. The second is Bluetree# for increasing scatternet. The advantages of these two schemes are as follows. (1) A tree structure can be maintained. (2) No master is also a bridge so the load on the master is reduced. (3) The number of links in a bridge is the minimum possible, thus making the overhead in the bridge lighter.
