基于邻居信息的蓝牙分散网动态构建算法

Algorithm of Dynamic Construction of Bluetooth Scatternet Based on Information of Neighbor Device

蓝牙网络的低功耗,无线通讯特性使其在无线网络应用领域有着广泛前景。对于组网算法的探讨有利于促进其在实际中的应用。根据设备的邻居结点信息,递归地在同一过程中完成匹克网和分散网的创建。这种组网算法避免了随机组网的盲目性,提高了分散网的稳定性和灵活性,使匹克网的分布尽量均匀,减小匹克网间的相互干扰,从而提高了网络的通讯效率。

The feature of low energy cost and wireless communication let the bluetooth network has a prospective future in the application in wireless network. The research of algorithm of network construction promote its application. According to the information of all of device ’s neighbor , a new algorithm could be figured out.It will finish the construction of piconet and scatternet in a same process by recursively constructing them. With this new algorithm, curtness brought by the random algorithm can be avoided and interference between piconets will also be reduced. The net will work more efficiently as the stableness and flexibility of scatternet are greatly improved.
