Some Improvements on Active Queue Management Mechanism Based on Adaptive Fuzzy Control

By Nguyen Kim Quoc, Vo Thanh Tu and Nguyen Thuc Hai


Active queue management operates at network nodes to control the number of packets in the queue of nodes, by actively receiving packets when the queue is not full, removing packets when the queue is full or notifying bottlenecks even in the embryonic period of the bottlenecks due to to-be-full queue. In recent years, scientists have used fuzzy logic to improve queue management mechanisms. Overall, these improvements have used Mamdani fuzzy system with a fixed structure with triangular functions for input and output variables, so they do not adapt to the changing state of the network. We propose a adaptive fuzzy control (AFC) model to improve the effectiveness of active queue management mechanisms
