  1. 1. Emulating the Internet of Things with QEMU

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Gyokan O. Osman; [2020-11-05]
    Nyckelord :nRF51; Nordic Semiconductor; QEMU; emulation; simulation; Bluetooth; GPIO; virtualization;

    Sammanfattning : This thesis project implements and evaluates the virtual nRF51 platform in QEMU. Thepurpose of the project is to be able to run nRF51 binaries in QEMU and find out whetherit is feasible to perform a full system emulation for IoT devices. The nRF51 platform isa wireless system on chip design with ARM® Cortex™ M0 from Nordic Semiconductor. LÄS MER

  2. 2. Erlang as an alternative to a non-functional language for communication in a faulttolerant IoT sensor network

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Jimmy Holdö; [2020-02-17]
    Nyckelord :Internet of Things; Wireless Sensor Network; Erlang; IEEE 802.15.4; ZigBee; Network topology;

    Sammanfattning : This thesis compares a C++ prototype and an Erlang prototype for an Internet ofThings application. Internet of Things applications are difficult to program becausethey consist of a distributed environment of heterogeneous devices, where each devicecan have limited resources and connectivity technologies.

  3. 3. Efficient Transmission over Unknown Channels

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Ranjitha Gubbi Suresh; [2020]
    Nyckelord :Multi-Layer Transmission; RBIR; HARQ; mixing layers; successive demodulation; Wi-Fi; Technology and Engineering;

    Sammanfattning : In recent years, digital transmission techniques have been continuously evolving by employing increasingly more advanced Modulation and Coding Scheme (MCS). However, when the wireless channel is varying rapidly, it is hard or even impossible for the transmitter to select the proper MCS. LÄS MER

  5. 5. Wireless Power Transfer : Machine Learning Assisted Characteristics Prediction for Effective Wireless Power Transfer Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Shamsul Arefeen Al Mahmud; [2020]
    Nyckelord :Wireless power transfer; Machine learning; Coupling strength estimation; Load impedance estimation; Multi-transmitter wireless power transfer systems; Trådlös kraftöverföring; maskininlärning; uppskattning av kopplingsstyrka; uppskattning av belastningsimpedans; Multisändare trådlösa kraftöverföringssystem;

    Sammanfattning : One of the main challenges in wireless power transfer (WPT) devices is performance degradation when the receiver’s position and characteristics vary. The variations in the system parameters such as load impedance and coupling strength in WPT devices affect performance characteristics such as output voltage and power. LÄS MER
