Method for installing a hierarchical network

摘要

The method involves assigning a sensor node when an initial operation has a hierarchical level. Another node temporarily forms a central hub that is provided with a lower hierarchical level. A synchronization frame is transmitted during a communication between sensor nodes or the central hub. The hierarchical level of the transmitted node is communicated to receiving nodes with the frame. The level of the former node is changed depending on the other level of the other node during or after communication, where an execution of the change depends on characteristics of the communication.
