Abstract :
Effects of impulsive arrivals of packets on the performance of carrier-sense multiple-access (CSMA) protocols are studied. A deterministic dynamic system is proposed to approximate the imbedded Markovian chain model of the CSMA system. Based on this approximation, the probability of overloading of the CSMA system due to impulsive input can be estimated, and the trajectory of the system states can be calculated. For engineering application purposes, a relaxation time is defined. Simulations are carried out which support the above-mentioned approaches
