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;

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.
