Abstract:
A method for transmission of one of a sequence of digital information packets over a transmission channel, the method comprising the steps:at a transmitter, computing a current value of a carrier-sense defer threshold, based at least in part on an observed ratio between at least two of recent packet transmission successes, recent packet collisions, and recent packet deferrals on said transmission channel;at said transmitter, computing a current value of a power level based at least in part on an observed ratio between at least two of recent packet transmission successes, recent packet collisions, and recent packet deferrals on said transmission channel;the carrier-sense defer threshold and power level computed by a method chosen to obtain a pre-selected and desired future ratio between at least two of recent packet transmission successes, recent packet collisions, and recent packet deferrals on said transmission channel, the desired ratio indicating a rate of packet transmission failures significantly greater than zero;using said current carrier-sense defer threshold value to determine when a carrier signal for another transmitter's digital information packet is present on the transmission channel, and deferring transmission until an absence of said other packet is detected; andtransmitting the digital packet from the transmitter over the transmission channel at said current power level.
