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.
