Meeting End-to-End Deadlines in Real-Time Networks Using Software Defined Networking (SDN)

Creator:: Almahdi, Rafid M.
Abstract:: Network flows in Real-Time (RT) systems need to meet stringent end-to-end deadlines in order for such systems to operate safely and reliably. Today, such systems use custom or domain specific network system designs to meet end-to-end deadlines and other constraints of real-time flows. In this work we explore the design...

Information theoretic approach to quantization and classification for signal processing, communications, and machine learning applications

Creator:: Thuan Nguyen D.
Abstract:: There are five main contributions of this dissertation. The first contribution is new closed-form expressions for channel capacity of a new class of channel matrices. The second contribution is the discovery of the structure for optimal binary quantizer and the associated methods for finding an optimal quantizer that maximizes mutual...

Architecture Optimizations for Memory Systems of Throughput Processors

Creator:: Gu, Yongbin
Abstract:: Throughput-oriented processors, such as graphics processing units (GPUs), have been increasingly used to accelerate general purpose computing, including machine learning models that are being utilized in numerous disciplines. Thousands of concurrently running threads in a GPU demand a highly efficient memory subsystem for data supply in GPUs. In this dissertation,...

Advanced time-varying approaches for modeling the multipath channel in wireless network

Creator:: Aljerme, Abdelkader A.
Abstract:: This dissertation proposes the use of advanced time-varying approaches for modeling the dynamics of the multipath channel in wireless communication networks. These advanced time-varying approaches include linear Kalman innovation models in observable block companion form, and neural network-based models. The e˙ectiveness of these type of models is evaluated through three...

Adaptive Streaming Methods using Dual Protocols and Reinforcement Learning

Creator:: Gatimu, Kevin
Abstract:: The ubiquity of high quality video and proliferation of mobile devices has contributed to an unprecedented rise in video consumption. HTTP, in conjunction with adaptive streaming, has become the de facto mechanism for delivering the vast majority of video as it readily caters to heterogeneous networks and devices. This dissertation...

Coding Techniques for Achieving Efficient Wireless Sensor Networks

Creator:: Qassim, Yousef M.
Abstract:: In this dissertation, we explored multiple coding techniques to reduce energy consumption, improve performance, and secure wireless sensor networks specifically and ad-hoc networks in general. With the introduction of Internet of Things (IoT) and 5G technologies, wireless sensor networks are quickly emerging as an important and key technology in the...

Dynamic and Dual Streaming Methods for H.264 Video and Parallel Performance Modeling

Creator:: Johnson, Taylor N.
Abstract:: Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless...

Information Theoretical Analysis of Self-Similar Trees

Creator:: Chunikhina, Evgenia V.
Abstract:: Tree-like patterns are ubiquitous in nature. Botanical trees, river networks, and blood systems are the most well-known examples of complex hierarchical systems met in observations. Interestingly, many of such systems exhibit statistical self-similarity. There are two main types of self-similarity: Horton self-similarity and Tokunaga self-similarity. Although there is an increased...

Development and Implementation of JetNet : A Decentralized Wireless Sensing Protocol

Creator:: Goins, Justin B.
Abstract:: Modern sensor network applications are often implemented wirelessly in order to lessen installation costs and reduce deployment times. Unfortunately, these wireless sensor network (WSN) nodes must often rely on batteries or energy harvesting techniques in order to sustain their operation and supply the power needed to maintain communication within the...

Learning hierarchical decomposition rules for planning : an inductive logic programming approach

Creator:: Reddy, Chandrasekhara K.
Abstract:: Artificial Intelligence (AI) planning techniques have been central to automating a gamut of tasks from the mundane route planning and beer production to the ethereal image processing of space-ship images. Of all the planning techniques, hierarchical- decomposition planning has been the technique most employed in industrial-strength planners. Hierarchical-decomposition planning is...
