Abstract: This paper presents a delay-dependent robust stochastic active queue management (AQM) scheme that can be implemented in the routers for stabilizing queues in transmission control protocol (TCP) communication networks. The linearized TCP/AQM system is modelled as a uncertain time-delay system with stochastic perturbations and time-varying network parameters. In this paper, a new flow m...

A Mobile ad-hoc network (MANET) is a self configuring infrastructure less network of mobile devices connected by wireless links. In MANET the proper maintenance of resources and link to avoid congestion is main issues. In this paper our motive is to get better utilization of resources and avoid congestion. For communication system uses queuing techniques, Traditional queuing techniques like Dro...

Out internet is growing dressily day and night. One of the major problem in internet is to reduce the loss of packet during transmission. There are various nodes or devices so called router, switch, hub, and repeater are there between sender and receiver. Since the responsibility of network layer to transfer the packet to source to destination. Router is a network layer device, which route the ...

Title of Dissertation: MULTIFRACTAL INTERNET TRAFFIC MODEL AND ACTIVE QUEUE MANAGEMENT Jia-Shiang Jou, Doctor of Philosophy, 2003 Dissertation directed by: Professor John S. Baras Department of Electrical and Computer Engineering We propose a multilevel (hierarchical) ON/OFF model to simultaneously capture the mono/multifractal behavior of Internet traffic. Parameter estimation methods are deve...

Multimedia applications requires certain QoS to meet certain functionality.QoS requirements include bandwidth guarantees and temporal guarantees. In this paper, we propose a novel method that uses a cross layer architecture in which information from Application layer is used with UDPLite in Transport layer and Active Queue Management (AQM) with SiViRED in Network Layer with modified dynamic map...

One of the major component in a QoS-enabled network is active queue management (AQM). Over the last decade numerous AQM schemes have been proposed in the literature. However, much recent work has focused on improving AQM performance through alternate approaches. This study focuses on an unbiased comparative evaluation of the various proposals. The evaluation methodology adopted is the following...

In this paper, the AQM controller of a first-order controller’s type is proposed. The model of TCP/AQM is described by a second-order system with time delay. An analytical approach to analyze the stability of TCP/AQM Networks is used, based on the D-decomposition method and lemma Kharitonov for quasipolynomial. The proposed method for design first-order controller is verified and compared with ...

Abstract This memo presents two recommendations to the Internet community concerning measures to improve and preserve Internet performance. It presents a strong recommendation for testing, standardization, and widespread deployme...

In this report we discuss the dynamics of heterogeneous TCP systems with propagation delays. Instead of studying the local linearized TCP dynamics, we study the global stability conditions and obtain the stability regions. Also we provide proof of periodic behavior of a single TCP connection when stability conditions are not met.
