  • Implementation of processor allocation in an N-Cube multiprocessor on Macintosh

    Creator:
    Liu, Jinyue
    Abstract:
    The processor allocation in an n-dimensional hypercube multiprocessor using buddy strategy, gray code strategy, and a new strategy is implemented on Macintosh. Our implementations show that when processor relinquishment is not considered (i.e. static allocation), all these strategies are optimal in the sense that each incoming request sequence is always...

  • Dynamic and Dual Streaming Methods for H.264 Video and Parallel Performance Modeling

    Creator:
    Johnson, Taylor N.
    Abstract:
    Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless...

  • Target-based coverage extension of 802.11 MANETs via constrained UAV mobility

    Creator:
    Johnson, Taylor N.
    Abstract:
    MANETs are known to be useful in situations where mobile nodes need to communicate and coordinate in dynamic environments with no access to fixed network infrastructure. However, connectivity problems can occur when sub-groups within a MANET move out of communication range from one another. The increasingly prolific use of UAVs...

  • Network Abnormalities in Routerless Networks on Chip

    Creator:
    Gambord, Ryan T.
    Abstract:
    Routerless networks on chip (NoCs) were recently introduced as an alternative to traditional mesh-based scalable networks, promising improved performance and scalability with a large decrease in power and area usage by the elimination of routing on in-flight packets. Without mitigation, most network designs, including routerless, are susceptible to loss of...

  • Maximum flow in planar digraphs

    Creator:
    Harutyunyan, Anna
    Abstract:
    Worst-case analysis is often meaningless in practice. Some problems never reach the anticipated worst-case complexity. Other solutions get bogged down with impractical constants during implementation, despite having favorable asymptotic running times. In this thesis, we investigate these contrasts in the context of finding maximum flows in planar digraphs. We suggest...

  • 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...

  • Massive MIMO Channel Characterization

    Creator:
    Assiri, Mohammad
    Abstract:
    It has been estimated that data traffic from the different mobile devices that range from smartphones to machine-to-machine (M2M) devices will exceed 15.9 exabyte per month by the year 2018. With this immense data growth, the current wireless communication systems suffer from the scarcity of the radio spectrum and eventually...

  • 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.,...

  • Variable sampling compensation of networked control systems with delays using neural networks

    Abstract:
    In networked control systems (NCS) information or packets usually flow from a sensor or a set of sensors to a remotely located controller. Then the controller processes the received information and sends a series of control commands to the actuators through a communication network which could be either wireless or...
