Channel hopping sequence generation with variable channel width

A node capable of generating a channel hopping sequence for communicating on a wireless mesh network, the node comprising a processor configured with code to perform operations comprising:

• receiving an indication of a group of channels, each channel including a respective frequency range for communicating on the wireless mesh network and available for use in the channel hopping sequence, wherein the channel hopping sequence defines an ordered sequence of channel numbers spanning multiple time slots;
• assigning a first channel, from the group of channels, to the channel hopping sequence at a first position in the channel hopping sequence;
• selecting an additional channel, from the group of channels, wherein the additional channel is adjacent to the first channel, wherein frequencies included in a combined width of the first channel and the additional channel are available for transmissions at the first position;
• and
• assigning a second channel, from the group of channels, to the channel hopping sequence at a second position in the channel hopping sequence, wherein the second channel is different from the first channel and the additional channel.

A wireless mesh network comprising multiple nodes,

• wherein at least one node of the multiple nodes is capable of generating a channel hopping sequence, such that each of the multiple nodes communicates on the wireless mesh network according to the generated channel hopping sequence,
• wherein the at least one node comprises a processor configured with code to perform operations comprising:
• receiving an indication of a group of channels, each channel including a respective frequency range for communicating on the wireless mesh network and available for use in the channel hopping sequence, wherein the channel hopping sequence defines an ordered sequence of channel numbers spanning multiple time slots;
• assigning a first channel, from the group of channels, to the channel hopping sequence at a first position in the channel hopping sequence;
• selecting an additional channel, from the group of channels, wherein the additional channel is adjacent to the first channel, wherein frequencies included in a combined width of the first channel and the additional channel are available for transmissions at the first position;
• and
• assigning a second channel, from the group of channels, to the channel hopping sequence at a second position in the channel hopping sequence, wherein the second channel is different from the first channel and the additional channel.
