Reinforcement learning in network control
With the rapid growth of information technology, network systems have become increasingly complex. In particular, designing network control policies requires knowledge of underlying network dynamics, which are often unknown, and need to be learned. Existing reinforcement learning methods such as …

Towards practical policies for network control
In the past three decades, several network control policies geared towards achieving throughput optimality have been developed. However, rarely any of these policies have been used in practice. We study three different issues that impede this transition and propose solutions that can facilitate the …

Practical algorithms for distributed network control
… practical issues prevent the adoption of these network control policies on the Internet. This thesis considers two distinct topics in distributed network control: (i) maximizing throughput in wireless networks using network coding, and (ii) deploying controllable nodes in legacy networks. …

Verifying the Performance of Network Control Algorithms
As networked systems become critical infrastructure, their design must reflect their new societal role. Today, we build systems with hundreds of heuristics but often do not understand their inherent and emergent behaviors. This dissertation presents, performance verification, a set of tools and …

Open network control : towards an integrated telecommunications future
Recent advances in the area of computer networking have led to a number of approaches to providing multi-service networks. Of particular importance are B-ISDN & ATM on the one hand, and the Internet, based on IP, on the other. The idea that the coupling of B-ISDN and ATM would provide the global …

Scalable Autonomous Network Control using Minimally Informed Agents
… scalable failure risk management in complex network infrastructures while returning tractable results. It does so by proposing methods of decentralised and distributed emergent risk identification and proactive mitigation, where assets, controlled by individual agents, use only limited …

Adaptive neural network control of discrete-time nonlinear systems
In this thesis, adaptive neural network control schemes are investigated for five classes of discrete-time nonlinear systems in affine/non-affine form. The systems studied include single-input single-output nonlinear systems, multi-input multi-output nonlinear systems. For affine systems, the …

Asymptotic performance of queue length based network control policies
In a communication network, asymptotic quality of service metrics specify the probability that the delay or buffer occupancy becomes large. An understanding of these metrics is essential for providing worst-case delay guarantees, provisioning buffer sizes in networks, and to estimate the frequency …

Neural network control of space vehicle orbit transfer, intercept, and rendezvous maneuvers
The feasibility of neural networks to control dynamic systems is examined. Control of a one-dimensional problem is initially investigated to develop an understanding of the structure and simulation of the neural networks. A nondimensional problem is also explored to apply a single neural network …

PLAYBACK BUFFERING AND CONTROL FOR LINEAR MULTIPLE INPUT MULTIPLE OUTPUT NETWORK CONTROL SYSTEMS
… derive a generalized switched system model for a control strategy aimed at stabilizing linear stable Network Control Systems (NCS). In some special cases, plant states can be brought to a desired set-point by applying a single control. For such systems, we mathematically prove that the control …

Optimization of stationary expansion planning and transient network control by mixed-integer nonlinear programming
Nowadays, transmission system operators of energy networks (TSO) have to enable secure energy supply even under challenging transport situations and increasing demand. Hence, they seek a stable network control and regularly expand the capacity of their networks. The challenging questions arise of …

On the Use of Network Control Techniques in Pursuit of Influence Spread in Complex Networks
A critical element in the process of control and influence spread is the selection of the seed nodes from which influence and control spreads. To be able to meet project aim and to develop more effective seed selection methods, first we need to understand the relationship between different global …
