一种改进的基于Bluetrees的蓝牙散射网形成算法

论述了蓝牙散射网的发展现状及网络协议,指出Bluetrees协议算法存在的问题:Bluetrees网组建不均衡时影响系统传输均衡性、未考虑设备的移动性对散射网的影响及可靠性问题.接着对形成Bluetrees的算法进行了改进,增强了系统以及Bluetrees的均衡性,考虑了设备的移入与移出对散射网的影响以及散射网的重组,增强了散射网中数据传输的可靠性.通过对该算法的改进和完善,减小了设备的移动对系统性能的影响,提高了系统的性能.最后以车队的相互通信和指挥控制为例说明了本文算法的应用.

Improved Bluetooth scatternet formation algorithm based on Bluetrees

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.
