Implementation of Fuzzy Logic for M/M/C Model in Packet Switched Network Using HoL Priority Queue

Abstract

In this paper, an HoL priority queue is utilised to give preference to some high priority traffic using fuzzy logic controller. The same controller is also used to choose the number of servers in M/M/C queue model since this represents the speed of service. The service rate has been altered between one and two for altering the C value in the queue. Using MATLAB, the queuing model is simulated and various performance metrics like utilization factor and mean delay time is obtained for a particular period of time. Also, the number of units have been kept at both high and low and based on that the service rate is altered.
