Energy Efficient Reduced Complexity Multi-Service, Multi-Channel Scheduling Techniques, Dan J. Dechene
Electronic Thesis and Dissertation Repository
The need for energy efficient communications is essential in current and next-generation wireless communications systems. A large component of energy expenditure in mobile devices is in the mobile radio interface. Proper scheduling and resource allocation techniques that exploit instantaneous and long-term average knowledge of the channel, queue state and quality of service parameters can be used to improve the energy efficiency of communication.
This thesis focuses on exploiting queue and channel state information as well as quality of service parameters in order to design energy efficient scheduling techniques. The proposed designs are for multi-stream, multi-channel systems and in general have …

Reliable And High-Performance Hardware Architectures For The Advanced Encryption Standard/Galois Counter Mode, Mehran Mozaffari-Kermani
Electronic Thesis and Dissertation Repository
The high level of security and the fast hardware and software implementations of the Advanced Encryption Standard (AES) have made it the first choice for many critical applications. Since its acceptance as the adopted symmetric-key algorithm, the AES has been utilized in various security-constrained applications, many of which are power and resource constrained and require reliable and efficient hardware implementations.
In this thesis, first, we investigate the AES algorithm from the concurrent fault detection point of view. We note that in addition to the efficiency requirements of the AES, it must be reliable against transient and permanent internal faults or …

Optical-Wimax Hybrid Networks, Abdou R. A. Ahmed
Electronic Thesis and Dissertation Repository
The emergence of bandwidth-intensive Internet services, such as
circuit-quality voice transfer and interactive video gaming, create
a high demand for a very qualified next-generation access network.
In addition to high bandwidth, these future access networks should
also provide improved network availability, flexibility, mobility,
reliability, failure protection, quality of service (QoS) support
and cost-effective access. The integration between optical networks
and Worldwide Interoperability for Microwave Access (WiMAX) is a
promising solution for future access networks. Accordingly, a few
different architectures and MAC protocol components have recently
been proposed for the integration between the Ethernet Passive
Optical Network (EPON) and WiMAX. However, …
