  • 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...

  • Resource allocation methods for quality-of-service provisioning in heterogeneous wireless networks

    Creator:
    Chakchouk, Nessrine
    Abstract:
    The increased use of mobile wireless devices that we have recently been witnessing, such as smartphones, tablets, e-readers, and WiFi enabled devices in general, is driving an unprecedented increase in the amount of data traffic. This fast market adoption of the wireless technology along with the tremendous success of multimedia...

  • Quality of Experience Assurance Methods in Mobile Heterogeneous Wireless Communication Systems

    Creator:
    Sinky, Hassan Hussein
    Abstract:
    The proliferation of mobile users and internet content has advanced a plethora of research areas. Among these areas include mobile networks, transport layer protocols, and smart cities. Research shows that global mobile data traffic will increase sevenfold reaching 49 exabytes per month by 2021, most of which will be mobile...

  • 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...

  • 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...

  • Towards Long Short Term Memory Based Proactive In-Network Caching for Cloud RANs

    Creator:
    Tirupathi, Chittibabu
    Abstract:
    The rapid population growth in large urban cities has led to an unprecedented increase in both the number and the diversity of wireless devices and applications with varying quality of service requirements in terms of latency and data rates. LinkNYC is an example of an urban communication network infrastructure, which...

  • 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...

  • 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...

  • Deep Learning Based Automatic Modulation Classication for Wideband Access Using Cyclostationarity Analysis

    Creator:
    Mejri, Seifeddine
    Abstract:
    RF-based signal identification and classification has received growing attention during recent years due to its potential use in many application domains. Of particular interest is Automatic Modulation Classification (AMC), which has been useful in addressing various spectrum related challenges such as signal jamming, policy enforcement, and spectrum sharing. Adopting AMC...

  • Opportunistic bandwidth sharing through reinforcement learning

    Creator:
    Venkatraman, Pavithra
    Abstract:
    The enormous success of wireless technology has recently led to an explosive demand for, and hence a shortage of, bandwidth resources. This expected shortage problem is reported to be primarily due to the inefficient, static nature of current spectrum allocation methods. As an initial step towards solving this shortage problem,...
