Channel Hopping Based on Channel Performance Statistics

A method of generating a channel hopping sequence for a link of a wireless communication device in a wireless sensor network, the method comprising:

• receiving a plurality of repetition factors for a plurality of respective frequency channels in the link, wherein a repetition factor for a frequency channel indicates a number of times the frequency channel is repeated in the channel hopping sequence;
• determining a set of frequency channels for generation of the channel hopping sequence based on the repetition factors;
• and
• generating the channel hopping sequence using the set of frequency channels.
