Pseudo Channel Hopping in Mesh Networks without Time Synchronization

Abstract:

A method for pseudo channel hopping in a node of a wireless mesh network is provided that includes scanning each channel of a plurality of channels used for packet transmission by the node, wherein each channel is scanned for a scan dwell time associated with the channel, updating statistics for each channel based on packets received by the node during the scanning of the channel, and selecting a channel of the plurality of channels for scanning based on the statistics when the scan dwell time of a currently scanned channel ends.
