摘要: 蓝牙节点的带宽和存储器容量有限,在蓝牙散射网中构造一条QoS通信路由是一个重大挑战。通过将平面图划分为若干子图,再将子图抽象为高层图,提出了一个用于蓝牙散射网的层次网络模型;并给出了子图的划分原则。适用于大规模蓝牙网络的层次管理模型可以实现分层管理、分块计算,减少控制分组数量,使网络具有更好的可扩展性。

Abstract: Bluetooth node is bandwidth-limited and memory-limited,constructing a QoS route for communication from one node to another in scatternet is a significant challenge.In this paper a hierarchical network model for Bluetooth scatternet is proposed through plotting out the flat graph into sub-graphs which are abstracted as high-level graph,and rules to partition the graph into sub-graphs is also given.A hierarchical management model for large scale bluetooth network can implement both hierarchical management and blocking calculation,and also significantly reduce the number of control packets and make bluetooth network to have larger extensibility.

Key words: ad hoc network, bluetooth, hierarchical network, scatternent, piconet
