Efficient And Secure Resource Allocation In Mobile Edge Computing Enabled Wireless Networks, Qun Wang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To support emerging applications such as autonomous vehicles and smart homes and to build an intelligent society, the next-generation internet of things (IoT) is calling for up to 50 billion devices connected world wide. Massive devices connection, explosive data circulation, and colossal data processing demand are driving both the industry and academia to explore new solutions.

Uploading this vast amount of data to the cloud center for processing will significantly increase the load on backbone networks and cause relatively long latency to time-sensitive applications. A practical solution is to deploy the computing resource closer to end-users to process the distributed …

Spectral, Energy And Computation Efficiency In Future 5g Wireless Networks, Haijian Sun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wireless technology has revolutionized the way people communicate. From first generation, or 1G, in the 1980s to current, largely deployed 4G in the 2010s, we have witnessed not only a technological leap, but also the reformation of associated applications. It is expected that 5G will become commercially available in 2020. 5G is driven by ever-increasing demands for high mobile traffic, low transmission delay, and massive numbers of connected devices. Today, with the popularity of smart phones, intelligent appliances, autonomous cars, and tablets, communication demands are higher than ever, especially when it comes to low-cost and easy-access solutions.

Understanding Security Threats Of Emerging Computing Architectures And Mitigating Performance Bottlenecks Of On-Chip Interconnects In Manycore Ntc System, Chidhambaranathan Rajamanikkam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Emerging computing architectures such as, neuromorphic computing and third party intellectual property (3PIP) cores, have attracted significant attention in the recent past. Neuromorphic Computing introduces an unorthodox non-von neumann architecture that mimics the abstract behavior of neuron activity of the human brain. They can execute more complex applications, such as image processing, object recognition, more efficiently in terms of performance and energy than the traditional microprocessors. However, focus on the hardware security aspects of the neuromorphic computing at its nascent stage. 3PIP core, on the other hand, have covertly inserted malicious functional behavior that can inflict range of harms at …

Optimizing The Advanced Metering Infrastructure Architecture In Smart Grid, Alireza Ghasempour

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The gathered data from smart meters in current advanced metering infrastructure (AMI) of smart grid is huge. This much data causes serious challenges for reliability, performance, and scalability of smart grid. Therefore, we have investigated the scalability of different AMI architectures and proposed a scalable hybrid AMI architecture. We formulated deployment cost of different AMI architecture and used a genetic-based algorithm to minimize the deployment cost for the proposed architecture. We simulated different AMI architectures for five demographic regions and the results proved that our proposed AMI hybrid architecture has a better scalability compared to other AMI architectures.

Design Of Reliable And Secure Network-On-Chip Architectures, Dean Michael B Ancajas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The trend towards massive parallel computing has necessitated the need for an On-Chip communication framework that can scale well with the increasing number of cores. At the same time, technology scaling has made transistors susceptible to a multitude of reliability issues. This dissertation demonstrates design techniques that address both reliability and security issues facing modern NoC architectures. The reliability and security problem is tackled at different abstraction levels using a series of schemes that combine information from the architecture-level as well as hardware-level in order to combat aging effects and meet secure design stipulations while maintaining modest power-performance overheads.

Parasitic Layer-Based Reconfigurable Antenna And Array For Wireless Applications, Zhouyuan Li

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Antenna is one of the most important components in wireless systems since signal transmission and reception are conducted through the antenna interface. Therefore, the signal quality is highly affected by the properties of the antenna. Traditional antennas integrated in devices such as laptops or cell phones have fixed radiation properties and can not be changed to adapt to different environments. Thus the performance of thefwhole system will be negatively affected since the antenna will not operate in the optimum status in different environments. To solve this problem, reconfigurable antenna, which can dynamically change its operation frequency, radiation pattern, and polarization, …
