TCP performance enhancement in wireless networks via adaptive congestion control and active queue management
… networks. Remedy to this problem has been an active research area. However, a widely accepted and adopted solution is yet to emerge. Difficulties of an acceptable solution lie in the areas of compatibility, scalability, computational complexity and the involvement of intermediate routers and …

Some Active Queue Management Methods for Controlling Packet Queueing Delay. Design and Performance Evaluation of Some New Versions of Active Queue Management Schemes for Controlling Packet Queueing Delay in a Buffer to Satisfy Quality of Service Requirements for Real-time Multimedia Applications.
… than traditional applications. For example, interactive multimedia applications, unlike traditional applications, have more strict delay constraints and less strict loss constraints. Unfortunately, the current Internet offers only a best-effort service to all applications without any consideration …

Performance modeling of congestion control and resource allocation under heterogeneous network traffic. Modeling and analysis of active queue management mechanism in the presence of poisson and bursty traffic arrival processes.
… in response to varying application scenarios. Active Queue Management (AQM) is a promising scheme to support end-to-end Transmission Control Protocol (TCP) congestion control because it enables the sender to react appropriately to the real network situation. Analytical performance models are …

A Framework for Designing a Low-Loss, Low-Delay Internet
Finally, we present a simple Active Queue Management scheme that we call the Adaptive Virtual Queue (AVQ) algorithm and provide design rules for selecting its parameters. We also provide a simple implementation of the AVQ scheme using a token-bucket formulation, which can be implemented with a few …

Enhancing TCP traffic flow performance with a proportional and integral rate controller: Theory, design, and performance evaluation
… shortcomings of RED and some other related AQM (Active Queue Management) techniques developed in recent years. That is to avoid unnecessary packet losses and stabilize the queue length in the router. It can also prevent the throughput reduction in the presence of wireless links. We proved the …

Solver for TCP flows in a network
… key factors such as packets discarding rate, queueing delay and the throughput of a bottleneck buffer. A network designer needs to predict these parameters in order to dimension a network properly. This thesis developed a solver for predicting the stability of a TCP network when servers …

Deterministic Fluid Models for Internet Congestion Control
… study the impact of parameter choice of an AQM (active queue management) scheme that can be used at the router. We argue that, depending upon the choice of the parameters of the AQM scheme, one would obtain a rate-based model or a rate-and-queue-based model as the deterministic limit of a …

Performance modelling and analysis of congestion control mechanisms for communication networks with quality of service constraints. An investigation into new methods of controlling congestion and mean delay in communication networks with both short range dependent and long range dependent traffic.
Active Queue Management (AQM) schemes are used for ensuring the Quality of Service (QoS) in telecommunication networks. However, they are sensitive to parameter settings and have weaknesses in detecting and controlling congestion under dynamically changing network situations. Another drawback for …

Novel algorithms for fair bandwidth sharing on counter rotating rings
… standardization process, weighted fairness and queue management schemes were proposed to be used in the standard. As shown in this dissertation, these schemes can be applied to solve the fairness issues noted widely in the research community as radical changes are not practical to introduce …

Performance evaluation of active network-based unicast and multicast congestion control protocols
This thesis investigates the application of the Active Networks (AN) paradigm in congestion control. ANs provide an alternative paradigm to solving network problems by allowing the network elements to perform computation. Thus, the AN is a promising paradigm to shorten the deployment time of new …

Noncooperative static and dynamic games: addressing shared constraints and phase transitions
… Protocol (TCP)-like rate control scheme with an Active Queue Management (AQM) router. The heterogeneity in the system is due to different user delays that are known and fixed but taken from a given distribution. It is shown that for any given distribution of delays, there exists a critical amount …
