1. A method in a wireless network comprising a plurality of frequency channels and a receiving participant, the method comprising:
- receiving data on a first subset of the plurality of frequency channels, wherein the frequency channels in the first subset are utilized at least once;
receiving data on a second subset of the plurality of frequency channels;
determining packet error rates for the respective frequency channels in the first and the second subsets;
selecting one of the plurality of frequency channels as an optimal frequency channel based on a result from the act of determining; and
determining long term evaluations of the respective frequency channels in the first and second subsets based on the packet error rates for the respective frequency channels in the first and the second subsets, and a first time constant; and
determining short term evaluations of the respective frequency channels in the first and second subsets based on the packet error rates for the respective frequency channels in the first and second subsets, and a second time constant, the second time constant being smaller than the first time constant;
wherein the one of the plurality of frequency channels is selected as the optimal frequency channel based on the short term evaluations if the long term evaluations of two or more of the frequency channels have a same evaluation value.
