摘要： A mesh tree formation system. In particular implementations, a method includes responsive to a selection of a channel potentially bearing a higher priority use, entering a silent state and initiating a channel scan of the selected channel for a period of time. The method also includes, responsive to receipt of an enabling signal, entering a limited transmission state that enables transmission of wireless frames on the selected channel. The method also includes, responsive to termination of the period of time of the channel scan wherein no higher priority use is detected, entering a full transmission state comprising transmission of enabling signals corresponding to the selected channel.

摘要： Methods, apparatuses and systems directed to synchronizing transmissions among parent and child routing nodes in a hierarchical wireless mesh network. In one implementation, the present invention employs a time slot scheduling algorithm to coordinate communications between wireless nodes of a hierarchical tree. In one implementation, the present invention provides a wireless mesh network where slot scheduling information propagates throughout the mesh, while individual nodes in the mesh compute their respective time slot schedules based on this information and the current state of the network. In one such implementation, a parent routing node computes its slot schedule and transmits certain parameters to its child nodes (as opposed to the schedule itself). The child node(s) then iterates the same scheduling function based on the parameters passed to it to determine the slots with which it should communicate to its parent node and its child nodes.
