The aim of this paper is to develop the membership functions of the system characteristic of a queuing g model with an unreliable server, in which the arrival rate, service rate, breakdown rate and repair rate are all fuzzy numbers. The -cut approach is used to transform a fuzzy queue with an unreliable server into a family of conventional crisp queues with an unreliable server. By using membe...

The algorithms of queue management in IP routers determine which packet should be deleted when necessary. The active queue management, recommended by IETF, enhances the efficiency of transfers and cooperate with TCP congestion window mechanism in adapting the flows intensity to the congestion of a network. The article investigates the influence of the way of choosing packets to be dropped (end ...

existence of capacity drop phenomenon, as the difference between pre-queue and queue discharge flow rates, has been one of the controversial concepts of traffic engineering. several researches have focused on capacity drop existence and also its estimation issues. this paper aims to estimate capacity drop based not only on a comparison between breakdown and queue discharge flow rates, but also ...

Traffic Management using Fuzzy Control System Propose a distributed traffic management, in this project Network simulators are used to reduce the traffic in networks. Traffic congestion control is one of the effective approaches to manage the network traffic. In this traffic management IntelRate Controller has been used to manage the Internet congestion.. It avoids various potential performance...

Queue management schemes at the routers and congestion avoidance schemes at the end points cooperate to provide good congestion solutions in computer networks. While queue management schemes are still being developed, research on congestion avoidance has come a long way to serve the bandwidth requirement of the networks. Because of considerable lack on the evaluation research work, there is no ...

In this paper, we investigate the fuzzy logic based system characteristics of MX/G/1 retrial queuing system with Bernoulli vacation schedule. The service time and vacation time are assumed to be generally distributed. It is found in many practical situations that the queuing models with fuzzy parameters are much more realistic than the classical crisp parameters based queuing models. We have...

Network congestion control is a complex problem that requires robust, possibly intelligent, control methodologies to obtain satisfactory performance. Designing effective congestion control strategies for computer networks is known to be hard because of the difficulty of obtaining realistic, cost effective, tractable analytical models. This renders the application of classical control system des...

1 – Fuzzy control of queues is a new method for controlling cost of the system, number of customers waiting in the queue and many other aspects of queues. This paper proposes fuzzy control approach for reducing cost of the system. 1 / / F M (Poisson arrival and fuzzy service rate) with flexible service time is examined in this paper. All the fuzzy mathematics rules in this paper are based on Za...
