提出了一个分布式散射网形成算法. 首先发现邻居节点 , 根据收集到邻居信息生成匹克网 , 该步结束 时整个区域内 蓝牙节点形成一系列 互不相连 的初始匹克网 然后选择桥节点 , 互连初始匹克网形成一个连通散射网 并严格保证任意两个毗邻匹克网在互连过程 中建立唯一 的连接. 通过一个角色转换 , 图桥节点角色得以确定. 可以运行的动态源路由协议类似算法实现散射 网的路由查找. 仿真试验结果表明 , 散射网具有较好特性-An asynchronous and distributed

scatternet construction algorithm was proposed. First , each node collects information for neighbors　 Then

all randomly distributed Bluetooth nodes are self- organized into a series of ini tial pico nets　 Fi nally , select

bridge nodes , initial piconets a re bridg ed toge ther into scatternet , alg orithm guarantees that any two

neighboring pico nets can be connected by one path and every bridge is as signed with an exact role by the

role transitio n diagram. Route discov ery for the scatternet can be realized by using the similar dynamic

source routi ng protocol. The sim ulation results confirm good function of created Blue too th scatternet
