Secure Cloud Controlled Software Defined Radio Network For Bandwidth Allocation, Isaac J. Cushman Jan 2017

Secure Cloud Controlled Software Defined Radio Network For Bandwidth Allocation, Isaac J. Cushman

Electronic Theses and Dissertations

The purpose of this research is to investigate the impact of mobility of wireless devices for opportunistic spectrum access and communications using National Instrument Universal Software Radio Peripherals devices. The overall system utilizes software defined radio networks for frequency allocation, cloud connectivity to maintain up-to-date information, and moving target defense as a security mechanism. Each USRP device sends its geolocation to query the spectrum database for idle channels. The cloud cluster was designed for complex data storage and allocation using a smart load balancer to offer ultra-security to users. This project also explores the advantages of data protection and security …


Solar Irradiance Forecasting And Implications For Domestic Electric Water Heating, Christopher Nutter Jan 2017

Solar Irradiance Forecasting And Implications For Domestic Electric Water Heating, Christopher Nutter

Electronic Theses and Dissertations

As the effects of burning fossil fuels continues to present its prevalence, the interests in alternative forms of energy is expanding. Within the home, the domestic electrical water heater accounts for approximately 17% of its energy consumption. Reducing the amount of energy required to produce hot water from this thermal system alone can have a significant effect on reducing its carbon footprint. In this presented work, a modeled domestic electrical water heater was supplied photovoltaic and on-grid electrical power to increase its energy efficiency. As photovoltaic (PV) energy is directly related to solar irradiation, it is important to receive accurate …


Energy Storage Management And Simulation For Nano-Grids, Shantu Ghose Jan 2017

Energy Storage Management And Simulation For Nano-Grids, Shantu Ghose

Electronic Theses and Dissertations

Energy storage has been utilized in many forms and applications from a flashlight to the Space Shuttle. There is a worldwide effort to develop battery model with high energy level and power densities for a variety range of applications, including hybrid electric vehicles (HEV) and photovoltaic system (PV). To improve battery technology, understanding the battery modeling is very important. So, modeling the thermal behavior of a battery is a vital consideration before designing an effective thermal management system which will operate safely and prolong the lifespan of an energy storage system. The first part of this work focused on the …
