摘要:
A method and apparatus for device discovery and channel selection in a wireless networking environment are described. As part of an automatic network configuration process, a super node sequentially traverses the available channels, broadcasting discovery messages including the channel switching schedule. Wireless nodes that receive those broadcast messages switch channels in lock step with the super node, sending discovery replies on those channels over which the broadcast discovery messages are successfully received. An association is generated identifying accessible nodes and the channels through which those nodes may be accessed. An optimum channel may then be selected based on this association information. Sub-nodes may repeat the broadcast discovery messages, and relay any discovery replies to the super node. The super node may then identify sub-nodes that may be used as proxies to access nodes that would otherwise be inaccessible.
