Fuzzy-logic-based Cell Discarding: Study on A New Scheme with Cost-effectiveness and Fairness in ATM Networks

This paper proposes a fuzzy-logic-based cell discarding scheme employing a new cell choice discipline. The proposed scheme serves the purpose of not only dropping cells fairly but minimizing the network resource volume consumed by lost cells. Two useful properties are derived of the weighted average fuzzy inference on the basis of "symmetric fuzzy sets". A new cell choice discipline, determined by a fuzzy quantitative relation featuring cost-effectiveness and fairness, is presented. The results obtained from simulation show that the proposed scheme can make a marked improvement on the average volume of lost network resources and the cell discarding fairness.
