Economically-aware bandwidth allocation framework in bandwidth-constrained networks
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2023-12-01

Bandwidth-sensitive oblivious routing
… algorithms either do not take into account the bandwidth demand, or assume that each flow has its own private channel to guarantee deadlock freedom. Though adaptive routing schemes can react to varying network traffic, they require complicated router designs. In this thesis, we present a …

Sampling based on local bandwidth
… of continuous-time signals based on local bandwidth is considered in this thesis. In an intuitive sense, local bandwidth refers to the rate at which a signal varies locally. One would expect that signals should be sampled at a higher rate in regions of higher local bandwidth, and at a lower …

Decoupling congestion control and bandwidth allocation policy with application to high bandwidth-delay product networks
… decouples the control of congestion from the bandwidth allocation policy. We show that the new protocol, called XCP, enables very large per-flow throughput (e.g., more than 1 Gb/s), which is unachievable using current congestion control. Additionally, we show via extensive simulations that XCP …

Bandwidth management and quality of service
With the advent of bandwidth-hungry video and audio applications, demand for bandwidth is expected to exceed supply. Users will require more bandwidth and, as always, there are likely to be more users. As the Internet user base becomes more diverse, there is an increasing perception that Internet …

Video transmission over constrained bandwidth channels
… multiple video streams over a reserved bandwidth network channel. The emerging services architecture in ATM networks as well as the Internet provide the capability to reserve resources such as bandwidth, and to use them to provide higher level services. We use simulation to consider the …

Dynamic bandwidth allocation in ATM networks
This thesis investigates bandwidth allocation methodologies to transport new emerging bursty traffic types in ATM networks. However, existing ATM traffic management solutions are not readily able to handle the inevitable problem of congestion as result of the bursty traffic from the new emerging …

Bandwidth Aggregation Across Multiple Smartphone Devices
… the Internet in one way or another. However, the bandwidth offered by these cellular networks is often much lower than we typically experience on our standard home networks, leading to a less-than-optimal user experience. This makes it very challenging and frustrating to access certain types of …

A Selective Approach to Bandwidth Overbooking
… technique used by network providers to increase bandwidth utilization. If the overbooking factor is chosen appropriately, additional virtual circuits can be admitted without degrading quality of service for existing customers. Most existing implementations use a single factor to accept a linear …

Latency-bandwidth tradeoffs in Internet applications
… by developing techniques that trade off one of bandwidth and latency to improve the other. We first consider the problem of supporting analytics over the large volumes of geographically dispersed data produced by global-scale organizations. Current solutions for analyzing this data as a whole …

Bandwidth-limited robust nonlinear spacecraft control
Robust large-angle spacecraft pointing and tracking by Variable Structure Control (VSC) are developed. The control of multiaxial attitude dynamics is a highly nonlinear problem, which can be resolved by exact feedback linearization with respect to attitude variables. This requires exact …

Ultra wide-bandwidth micro energy harvester
An ultra wide-bandwidth resonating thin film PZT MEMS energy harvester has been designed, modeled, fabricated and tested. It harvests energy from parasitic ambient vibration at a wide range of amplitude and frequency via piezoelectric effect. At the present time, the designs of most piezoelectric …

Towards high-bandwidth scanning impedance imaging
… industry. By using a system of high-bandwidth impedance sensors and drive electronics, the physical constituents of ICs such as buried/surface dielectrics, buried/surface conductors and PN junctions could be detected. This thesis takes an initial step toward high-bandwidth …

DECENTRALIZED NETWORK BANDWIDTH PREDICTION AND NODE SEARCH
… manage and exploit end-to-end network bandwidth information from hosts on wide-area networks. Inspired by the finding that Internet bandwidth can be represented approximately in a tree metric space, we focus on three specific research problems. First, we have designed a decentralized …

Scalable Bandwidth Management in Software-Defined Networks
There has been a growing demand to manage bandwidth as the network traffic increases. Network applications such as real time video streaming, voice over IP and video conferencing in IP networks has risen rapidly over the recently and is projected to continue in the future. These applications …
