Abstract

In embodiments of the present invention improved capabilities are described for using a node in a mesh network to perceive a plurality of channels within a mesh network; selecting a first channel from the plurality of channels within the mesh network with the node; remaining on the first channel with the node for a predefined duration; remaining on the first channel beyond the predefined duration in order to receive a message if a signal is detected during the predefine duration; and selecting a second channel with the node once the predefined duration has elapsed without the signal detected.

Claims (11)

1. A method for operating a node in a wireless mesh network comprising:

using a computer, scanning each one of a plurality of channels in a wireless mesh network in a predetermined order for a predetermined duration to detect a preamble;

detecting the preamble on one of the plurality of channels;

remaining on a current one of the plurality of channels to receive a message after the predetermined duration when the preamble includes a first number of symbols;

changing to another one of the plurality of channels according to a command in the preamble when the preamble includes a second number of symbols; and

resuming scanning each one of the plurality of channels after the message is received.

2. The method of claim 1 wherein the message includes a plurality of messages.

3. The method of claim 1 wherein the message includes a command.

4. The method of claim 3 wherein the command relates to a communication speed.

5. The method of claim 3 wherein the command relates to a communication channel.

6. The method of claim 3 wherein the command relates to a communication channel availability.
