DYNAMIC ADJUSTMENT OF CCA THRESHOLD BASED ON DETERMINED VARIANCE OF CHANNEL TRANSMIT ATTEMPT FAILURE RATE RELATIVE TO EXPECTED VARIANCE ACROSS AVAILABLE TRANSMISSION CHANNELS
DYNAMIC ADJUSTMENT OF CCA THRESHOLD BASED ON DETERMINED VARIANCE OF CHANNEL TRANSMIT ATTEMPT FAILURE RATE RELATIVE TO EXPECTED VARIANCE ACROSS AVAILABLE TRANSMISSION CHANNELS
In one embodiment, a method comprises determining, by a network device in a wireless data network, that a prescribed Clear Channel Assessment (CCA) threshold is unsuitable for use on an identified wireless network channel among available wireless network channels, based on a determined variance of a corresponding channel transmit attempt failure rate for the identified wireless network channel, relative to an expected variance in channel transmit attempt failure rates that is determined across the respective available wireless network channels; and selectively adjusting the corresponding CCA threshold for the identified wireless network channel, until a second determined variance of the corresponding channel transmit attempt failure rate, at the identified wireless network channel, falls below a prescribed channel failure rate variance factor relative to the expected variance.
