State predictive LQI congestion control for TCP/AQM networks considering effective equilibrium points
نویسنده
چکیده
The purpose of this paper is to design state predictive LQI congestion controllers by considering effective equilibrium points of nonlinear models of TCP/AQM networks and to illustrate the effectiveness of the designed congestion controllers via the ns-2(Network Simulator ver.2) simulator. First nonlinear models of TCP/AQM networks are linearized at equilibrium points and a method to configure the equilibrium points of the models of TCP/AQM networks is proposed by focusing on the effective probabilities of packet marks. Second congestion controllers are designed by using state predictive control and LQI control. Finally the designed controllers are implemented in the router of TCP/AQM networks and simulation results are shown to illustrate the effectiveness of the designed congestion controllers by using SIMULINK and the ns-2 simulator.

A Design of Gain-scheduled Congestion Controllers using State Predictive Observers
In this paper, a design problem of congestion controllers is discussed for TCP/AQM(Transmission Control Protocol/Active Queue Management) networks. The proposed method consists of two control techniques. First one is based on a gain-scheduling technique considering nonlinearities of TCP/AQM networks. But the designed congestion controller is a state feedback controller and it is impossible to e...

This paper presents how generalized predictive control can improve the performance of TCP/IP networks when dealing with control congestion. Predictive control and GPC (Generalized Predictive Control), in particular, can be seen as an improved AQM (Active Queue Management) method. Predictive controllers, constrained and unconstrained, are compared with other control methods, such as PI control o...
متن کاملModels and Analysis of TCC/AQM Schemes over DiffServ Networks
QoS-enabled networks consist of major functions: one is a TCP congestion control (TCC) mechanism at a source/sink node and the other is an active queue management (AQM) scheme at an intermediate node. In this paper, we introduce the major TCC mechanisms and AQM schemes, and provide analytical models and simulation-based comparisons of these TCC/AQM schemes for the purpose of identifying the rec...
