The current development of the Bluetooth scatternet and protocol are described and some existing problems in Bluetrees algorithm are pointed out. For example, the unbalanced set-up of Bluetrees scatternet would affect the balance of system transmission, and the effect of device movement on scatternet and dependability is not taken into account. An improvement on the Bluetrees algorithm is proposed. This improvement enhances the harmonies of the system and Bluetrees, takes the influence of device movement and scatternet reformation into account, and strengthens the dependability of data transmission in the scatternet. Thus the equipment movement impact on systematic function is reduced, and the systematic performance is improved. At last, as an example, the algorithm is applied to the intercommunication and command-control in a motorcade.
