Abstract

A mathematical model of access method “carrier sense multiple access with collision avoidance” for two active stations was proposed. The effect of carrier capture and unimodal dependence of the operating characteristics from the initial width of the contention window was detected. Measures of preventing the effect of carrier capture, based on the modifications of the standard protocol were proposed. For research into the capture effect with a large number of rivals, a simulation model of the competition process was developed. The efficiency of prevention measures ensuring fair distribution of a jointly used time resource within a shared communication medium with an insignificant decrease in the general throughput of the access method has been shown.
