Bluetree#: An Extendable Bluetooth Scatternet Formation Using Only Slave/Slave Bridges

由於無線網路持續地快速成長，人類的生活也隨之變得更方便及舒適，在短距離傳輸的無線網路世界裡，藍芽是關鍵的技術之一。藍芽裝置的角色可以區分為主動、從動和橋接裝置三種，然而在網路傳送資料時主動和橋接這兩種裝置是流量的瓶頸點，新的藍芽散射網路結構是需要以便獲得有較佳的頻寬品質及較低的電源損耗。此篇文章將提出兩種新的演算法，一是為了提升散射網路傳輸效能所提出的Bluetree++，另一是提升散射網路的規模所提出的Bluetree#，這兩種方案的優點如下所述：(1)維持樹的結構，(2)沒有主動橋接裝置，所以主動裝置的負擔較少，(3)連接橋接裝置的總數量為最小，所以可使橋接節點造成的負載較輕。

With 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.
