  • Fast data replenishment in peer to peer networks

    Creator:
    Dhamodaran, Arul Nambi
    Abstract:
    Peer-to-Peer (P2P) based distributed storage systems have gain much popularity in recent years. These systems rely greatly on the data redundancy to be robust under network dynamics, i.e., the dynamics of peer entering and departing the network. Hence, it is important to implement mechanisms for maintaining a certain level of...

  • Coding Techniques for Achieving Efficient Wireless Sensor Networks

    Creator:
    Qassim, Yousef M.
    Abstract:
    In this dissertation, we explored multiple coding techniques to reduce energy consumption, improve performance, and secure wireless sensor networks specifically and ad-hoc networks in general. With the introduction of Internet of Things (IoT) and 5G technologies, wireless sensor networks are quickly emerging as an important and key technology in the...

  • Task Grapher : task graph scheduling in multiprocessor computer systems

    Creator:
    Chu, Lee-Jung Julie
    Abstract:
    This report presents a graphical tool for implementation of the scheduling heuristics provided by Kruatrachue. The input of scheduling is a task graph and the output is a schedule in the form of a Gantt chart. The implemented scheduling heuristics are: 1) Hu's HLF (highest level first) algorithm. 2) Yu's...

  • Coordinating secondary-user behaviors for inelastic traffic reward maximization in large-scale DSA networks

    Creator:
    NoroozOliaee, MohammadJavad
    Abstract:
    We develop efficient coordination techniques that support inelastic traffic in large-scale distributed dynamic spectrum access DSA networks. By means of any learning algorithm, the proposed techniques enable DSA users to locate and exploit spectrum opportunities effectively, thereby increasing their achieved throughput (or "rewards" to be more general). Basically, learning algorithms...

  • LacEDAemon : a programming environment for the multiparadigm language leda

    Creator:
    Pandey, Rajeev K.
    Abstract:
    Multiparadigm programming languages are a recent development in the realm of programming languages. A multiparadigm programming language allows the use of multiple, differing programming paradigms without departing from a single, unified linguistic framework. Multiparadigm programming languages are claimed to have benefits to both pedagogy and complex application creation. The beneficial...

  • Low-complexity high-speed VLSI design of low-density parity-check decoders

    Creator:
    Cui, Zhiqiang
    Abstract:
    Low-Density Parity-check (LDPC) codes have attracted considerable attention due to their capacity approaching performance over AWGN channel and highly parallelizable decoding schemes. They have been considered in a variety of industry standards for the next generation communication systems. In general, LDPC codes achieve outstanding performance with large codeword lengths (e.g.,...

  • Design and Analysis of Distributed Resource Allocation Techniques for Large-Scale Dynamic Spectrum Access Networks

    Creator:
    NoroozOliaee, MohammadJavad
    Abstract:
    The widespread use of wireless devices that we have recently been witnessing, such as smartphones, tablets, laptops, and wirelessly accessible devices in general, is causing an unprecedented growth in the required amount of the wireless radio spectrum. On the other hand, the spectrum resource has, for the last several decades,...

  • Efficient decoder design for error correction codes

    Creator:
    He, Jinjin
    Abstract:
    Error correction codes (ECCs) have been widely used in communication systems and storage devices. Nowadays, the rapid development of integrated circuit technologies makes feasible the implementation of powerful ECCs such as turbo code and low-density parity-check (LDPC) code. However, these high-performance codes require complex decoding algorithms, resulting in large hardware...

  • Network coding in relay networks

    Creator:
    Alban, Eduardo
    Abstract:
    Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Cooperative diversity has been proposed as an implementation for networks where terminals are restricted to using...
