Some Fuzzy Logic Based Congestion Control Methods: A Review
نویسندگان
چکیده
Congestion is the problem that occurs due to saturation of network resources. Despite the implementation of traditional congestion control algorithms such as Transmission Control Protocol (TCP/IP), congestion remains a critical issue in computer and ATM networks. Fuzzy Logic is applied to solve the congestion control problem as communication networks are difficult to model using traditional control system theory. Fuzzy Logic Systems are model free systems that rely on expert knowledge to generate control decision. Fuzzy Logic based congestion control outperforms the traditional methods in several cases .This paper is a review of Fuzzy Logic and Neural-Fuzzy based techniques that are applied to deal with congestion. Fuzzy Logic based Congestion Controller is a model free controller that utilizes qualitative reasoning to implement non-linear control functions efficiently.

Fuzzy Backward Congestion Noti cation (FBCN) Congestion Control in Asynchronous Transfer Mode (ATM) Networks
In this paper, we study the performance of a fuzzy control scheme as a rst step to develop better control strategies for avoiding congestion and attaining high link utilisation in ATM based networks. Due to the complexity of ATM networks and many parameters involved, explicit modeling of their dynamic behaviour is very di cult if not impossible. On the other hand, for systems which are di cult ...
متن کاملCongestion Control in Computer Networks using Fuzzy Logic
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...

Existing congestion controllers have been designed with TCP traffic in mind. Changing traffic patterns on the Internet imply that on some tight links all UDP video streams will occur. Three different congestion controllers (RAP, TFRC, and fuzzy-logic based), already successful in avoiding instability in current TCPdominated internets, were tested across a tight link in which video traffic domin...
