“…For example, an adversary may deploy multiple jamming devices to interfere with the radio communications of UAV delivery systems, which may disrupt the effectiveness of delivery [32,33]. Trends in aerial cognitive networks [34,35] will require intelligent strategies of UAV robust communications in urban and contested environments. In addition, the UAV can collect information (e.g.…”

The recent Federal Aviation Administration (FAA) approval of Unmanned Aerial Vehicle (UAV) testing will transform our daily lives. Because of the inherent flexibility, ease of use, and low cost to operate; UAV-based delivery systems will become tremendously popular in the near future. In this paper, we address the issue of cyber-physical scheduling of UAV resources in order to achieve an efficient delivery service. Particularly, to reduce the overall delivery time, we develop a weight-based scheduling scheme, which considers the priority and delivery distance of service requests. To maximize the probability of effectively handling service requests with a limited number of UAVs, we first formalize the problem as an optimization problem and then use a dynamic programming approach to solve the problem. Through a simulation study, our data shows that the service delivery delay and the probability of successfully handling UAV services requests can be significantly improved upon in comparison with existing baseline schemes.

“…Also, dynamic spectrum management using CRs can offer significant energy savings in radio networks [35]. Thus, significant energy savings coupled with the ability to perform dynamic spectrum management empowers CRs for applications such as air-ground communication systems [101,102]. which are termed as E1 and E2 respectively.…”

To seamlessly support the existing and upcoming wireless communication standards, the software defined radio (SDR) has been proposed as a solution. SDRs can process signals of different wireless communication standards by software reconfiguration of the same transceiver architecture, thereby reducing hardware resource utilization and associated costs. To perform multi-standard channelization, i.e., extraction of desired radio channels (frequency bands) from a wideband input signal, SDR receivers typically employ variable digital filters (VDFs) and filter banks that provide variable frequency responses by controlling a small set of parameters. VDFs and filter banks are also used in SDR based cognitive radios (CRs) to perform spectrum sensing (detection of presence/ absence of licensed user signals in a wideband input frequency range) for dynamic spectrum access, to achieve opportunistic and efficient usage of the radio frequency spectrum. Realizing such VDFs and filter banks which showcase the desired attributes of high frequency response flexibility and low implementation complexity is a challenging task. To address this challenge, new algorithms and various architectures for designing VDFs and filter banks have been proposed in this thesis. The first work presents design techniques to obtain variable frequency responses using the same set of prototype filter coefficients, along with the corresponding mathematical formulations. Two techniques are proposeda modified coefficient decimation method (MCDM) and the improved coefficient decimation method (ICDM), the latter being a combination of the proposed MCDM and the conventional coefficient decimation method (CDM). Both the proposed techniques, i.e., MCDM and ICDM, involve selective usage of filter coefficients by performing operations such as replacing them by zeros and retaining/ discarding them appropriately to obtain variable frequency responses. The ICDM is categorized into ICDM-I and ICDM-II, each comprising of two distinct coefficient decimation operations. The ICDM provides discrete control over the bandwidths and center frequencies of the subbands in the obtained frequency responses. iv The second work presents the design of VDFs which can be used for channelization in SDR receivers. Three such VDFs, one each based on ICDM-I, ICDM-II and comprehensive ICDM are proposed and analysed. The comprehensive ICDM based VDF involves both ICDM-I and ICDM-II operations and features their constituent advantages while minimizing the effects of their individual limitations. The comprehensive ICDM based VDF can provide variable lowpass, highpass, bandpass, bandstop and multi-band frequency responses on-the-fly, by performing appropriate ICDM operations on the same set of prototype filter coefficients. Similar to the design of VDFs based on ICDM-I, ICDM-II and comprehensive ICDM, the third work presents design of filter banks based on these three techniques. While the ICDM-I based filter bank can only be used for uniform channelization, the ICDM-II and comprehensive ICDM ...

I would like to dedicate this dissertation to my husband Kenneth. Without his love, sacrice, and support this accomplishment would not have been possible. I also dedicate this dissertation to my children Melanie, Douglas, Thomas, Amanda, and daughter-in-law Samantha for their unwavering emotional support-they are my biggest fans. I must include my granddaughter, Jadyn, for providing fun and recreation during my rst year at Iowa State University by taking me to all of the playgrounds in Ames, Iowa and schooling me in the strategy of the game "Trouble". Dedication also goes to Dorothy and Eugene Hlavacek for providing babysitting and family support during my military career. Finally, I dedicate this dissertation to my parents Samuel and Shirley Craig. They instilled the love of lifelong learning and the appreciation of a hard day's work. They are not here to see the conclusion of my eorts, but I know they are proud. iii TABLE OF CONTENTS LIST OF TABLES .
