AQM Shell Development - Creating a Framework for Airspace and Airfield Operations and Air Quality Visualization Software
… computer program. This program, named AQM for its purpose in assisting development of Air Quality Models, provides a working framework for future development of software for detailed air quality analysis and visualization.

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.
… 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 powerful tools which can be …

Deterministic Fluid Models for Internet Congestion Control
… then 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 …

Network level performance of differentiated services (diffserv) networks
… Random Exponential Marking (REM), an existing AQM scheme is studied under a new continuous time model, and its local stable condition is presented. Next, a novel virtual queue and rate based AQM scheme (VQR) is proposed, and its local stability condition has been presented. Then, a new AQM …

Solver for TCP flows in a network
… when servers implement Active Queue Management (AQM) schemes. The solver analyzes two AQM schemes. One is Random Early Detection (RED) and the other is Dynamic Random Early Detection (DRED). We verify the analysis of the solver through the simulation of a small network with multiple bottlenecks …

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 …

A Framework for Designing a Low-Loss, Low-Delay Internet
… then compare its performance to other well-known AQM schemes.

Enhancing TCP traffic flow performance with a proportional and integral rate controller: Theory, design, and performance evaluation
… the 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 …

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.
… thesis three existing Active Queue Management (AQM) mechanisms are modified by incorporating into these a control function to condition routers for better Quality of Service (QoS). Specifically, delay is considered as the key QoS metric as it is the most important metric for real-time multimedia …

Noncooperative static and dynamic games: addressing shared constraints and phase transitions
… Nonlinear network flow control with AQM feedback: The last part of this thesis investigates stability, bifurcation and oscillations arising in a communication network model with a large number of heteroge- neous users adopting a Transmission Control Protocol (TCP)-like rate control …

TCP performance enhancement in wireless networks via adaptive congestion control and active queue management
… indication algorithm at the links (i.e., AQM) by means of packet marking, and a effective loss differentiation algorithm at the source by careful examination of the congestion marks carried by the duplicate acknowledgment packets (DUPACK). Several improvements to the proposed TCP-Jersey …

Enabling Theoretical Model Based Techniques for Simulating Large Scale Networks
… we characterize the interaction between TCP and AQM, determine necessary scheduling rules to regulate TCP traffic, and incorporate the rules into a simulation engine. Although both fluid model based and network calculus based simulation give encouraging results in terms of the execution time, …

Applications of Deep Learning, Machine Learning, and Remote Sensing to Improving Air Quality and Solar Energy Production
… sparseness of regulatory air quality monitoring (AQM) stations. This motivates novel low-cost methods to estimate ground-level PM2.5 at a fine spatial resolution so that PM2.5 exposure in epidemiological research can be better quantified and local PM2.5 hotspots at a community-level can be …
