Abstract: Carrier sensing and power control, or trade-off among two or more communication parameters, can provide relative improvement in throughput. A sensing threshold or transmission power are varied, thus altering a sensing range and a transmission quality, thus maximizing a feasible transmission rate. Transmission power and rate are collectively altered to find a best throughput rate. A transmission rate can incremented after successful transmission and decremented after failed transmission, the described increment possibly being less than the described decrement. Thus, pairs of transmissions where one fails and one succeeds decrease the net transmission rate. Smaller increments, with larger decrements, cause increases to increase throughput without degrading quality, while causing decreases to restore transmission quality if an increase does degrade transmission quality.
