  • Collaborative Filtering-Based In-Network Content Placement and Caching for 5G Networks

    Creator:
    Alorayj, Haya
    Abstract:
    As the number of wireless devices, the demand for high data rates, and the need for always-on connectivity are growing and becoming more stringent with the evolvement and emergence of 5G systems, network engineers and researchers are being faced with new unique challenges that need to be addressed. Among many...

  • The Impact of Network Topology on Software Defined Network Performance

    Creator:
    Alhamar, Sara N.
    Abstract:
    Software Defined Network (SDN) is a new networking concept in which the data plane is decoupled from the control plane. Due to the huge demand on network resources and the rapidly increasing numbers of devices needing to be connected to the network, SDN paradigm has emerged as a potential solution...

  • Energy-efficient routing for delay-constrained data traffic in linear wireless sensor networks

    Creator:
    Alesaimi, Hani
    Abstract:
    Linear wireless sensor networks (LWSN) are special class of wireless sensor networks where sensor nodes are deployed in a straight line. Monitoring industrial pipelines, railroads, tunnels, power lines, and borders are applications of LWSNs. Wireless sensors are tiny devices with limited energy resources; therefore, efficient energy routing in LWSNs is...

  • One-to-many node disjoint paths routing in generalized hypercube, dense Gaussian, and hexagonal mesh networks

    Creator:
    Alsaleh, Omar I.
    Abstract:
    Routing from a single source node to multiple destination nodes using node disjoint paths (NDP) has many important applications in parallel systems. For example, if a source node wants to send distinct messages to distinct destination nodes, then the one-to-many NDP routing is useful. Unlike parallel systems with shared-memory, each...

  • Malicious-proof and fair credit-based resource allocation techniques for DSA systems

    Creator:
    AlShammari, Tamara
    Abstract:
    In this paper, we propose a credit-based resource allocation technique for dynamic spectrum access (DSA) systems that is robust against malicious and selfi sh behaviors and ensures good overall system fairness performance while also allowing spectrum users to achieve high amounts of service. We also propose a new objective function...

  • 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,...

  • Hybrid, Proactive In-Network Caching for Mobile On-Demand Video Streaming

    Creator:
    Abuhadra, Ragda
    Abstract:
    Mobile video streaming has become an essential application in mobile wireless networks,making up most of the mobile data of today’s Internet traffic. Studies have shown that mobile video data is projected to make up about 78 percent of the global mobile data traffic, and that global mobile data traffic is...

  • Enhancing macrocell downlink performance through femtocell user cooperation

    Creator:
    Zaid, Adem Mabruk
    Abstract:
    This thesis studies cooperative techniques that rely on femtocell user diversity to improve the downlink communication quality of macrocell users. We analytically analyze and evaluate the achievable performance of these techniques in the downlink of Rayleigh fading channels. We provide an approximation of both the bit-error rate (BER) and the...

  • Architectures and algorithms for dynamic overlay networks

    Creator:
    Abdelwahab, Sherif
    Abstract:
    Most of today’s Internet of Things (IoT) applications assume that data will be moved offdevices into centralized cloud platforms. While existing IoT systems leverage cloud-based analytics for meaningful data reasoning, the assumption that data should always be moved off the devices is problematic. The amount of data to be moved...

  • Jamming Attack Resiliency and Performance Analysis of Cognitive Radio Communication Networks

    Creator:
    Adem, Nadia
    Abstract:
    Cognitive radio technology emerges as a promising solution for overcoming shortage and inefficient use of spectrum resources. In cognitive radio networks, secondary users, which are users equipped with cognitive radios, can opportunistically access spectrum assigned to primary users, the spectrum license holders. Although it improves spectrum utilization efficiency, this opportunistic...
