`
`ABSTRACT
`(57)
`An approach for selecting sets of communications channels
`involves determining the performance of communications
`channels. A set of channels is selected based on the results of
`performance testing and specified criteria. The participant
`generates data that identifies the selected set of channels and
`provides that data to other participants of the communications
`network. The participants communicate over the set of chan(cid:173)
`nels, such as by using a frequency hopping protocol. When a
`specified time expires or monitoring of the performance of the
`channel set identifies poor performance of the set of channels,
`the participant selects another set of channels for use in com(cid:173)
`munications based on additional performance testing. By
`selecting channels based on the initial performance testing
`and performance monitoring, the communications network
`adaptively avoids channels with poor performance.
