  1. 1. Machine Learning assisted gNodeB Data Link Layer Capacity Management

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Adam Axelsson; [2023]
    Nyckelord :machine learning; telecommunications; 5g; packet losses; pacing algorithm;

    Sammanfattning : In the uplink direction of 5G New Radio, signals are sent between Ra-dio Units and Digital Units. The production of these signals is non-deterministic, leading to signals often being produced in bursts. Thesesignal bursts can lead to exceeding the Data Link Layer capacity, whichcauses packet losses. LÄS MER

  3. 2. A Comprehensive Taxonomy of Attacks and Mitigations in IoT Wi-Fi Networks : physical and data-link layer

    M1-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Sarmed Almjamai; [2022]
    Nyckelord :Attack; Mitigation; Tools; Vulnerability; Security protocol; WPA2; WPA3; Wi-Fi; IoT; physical layer; data-link layer; MitM; DoS; Key-recovery; Traffic decryption;

    Sammanfattning : The number of Internet of Things (IoT) devices is rising and Wireless Fidelity (Wi-Fi) networks are still widely used in IoT networks. Security protocols such as Wi-Fi Protected Access 2 (WPA2) are still in use in most Wi-Fi networks, but Wi-Fi Protected Access 3 (WPA3) is making its way as the new security standard. LÄS MER

  4. 3. Implementation of LPWAN protocols for Water Sense : Integration of LoRa and Contiki OS with the Rime stack

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Barry Dyi; [2022]
    Nyckelord :Contiki; LoRa; Telecommunications; Embedded Systems; WSN; IoT;

    Sammanfattning : The purpose of this thesis rose from tackling a specific project led by Cybercom Group. Water Sense was proposed after municipalities expressed the need to conveniently conduct measurements on water in Swedish lakes, and remotely get access to these data. LÄS MER

  5. 4. Simulering och analys av attacker riktade mot datalänklagret

    Kandidat-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Mohamad Jemmo; Kaler Laresé; [2022]
    Nyckelord :;

    Sammanfattning : OSI-modellens lager möjliggör kommunikation mellan nätverksenheter, men de kan också öppnaupp för attacker, eftersom det är svårare att upptäcka attacker mellan lager än attacker som skerdirekt på det lagret [1]. En attack på ett lager kan därmed öppna upp för attacker på andra lager. LÄS MER

  7. 5. Implementation of an IO-Link Master : A Research project to find out what it takes to get started with IO-Link

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Marcus Niklasson; Simon Uddberg; [2022]
    Nyckelord :IO-Link; Indusrty 4.0; MAX14819;

    Sammanfattning : IO-Link is a constantly growing market, bringing more interested parties who want to know if it is a market worth investing in. While deciding if the market is worth investing in is for the companies to decide, this thesis aims to shed some light on what it takes to get started with IO-Link development which could help that decision.
