  1. 1. Hantering av nätverkscache i DNS

    Kandidat-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Författare :Hans Lindqvist; [2019]
    Nyckelord :Caching name server; DNS; Internet of Things; Ipv6; Unbound; PowerDNS Recursor; Cachande namnserver; DNS; Sakernas Internet; Ipv6; Unbound; PowerDNS Recursor;

    Sammanfattning : The Domain Name System, DNS, is a fundamental part in the usability of the Internet, but its caching function is challenged by the increase of address size, number of addresses and automation. Meanwhile, there are limits in the memory capacity of certain devices at the Internet’s edge towards the Internet of Things. LÄS MER

  2. 2. Building Distributed Systems for Fresh and Low-latency Data Delivery for Internet of Things

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

    Författare :Adnan Toutounji Alkallas; [2019]
    Nyckelord :Edge computing; cloud computing; distributed systems; IoT; Age of Information; Edge computing; molntjänster; distribuerade system; sakernas; Age of Information;

    Sammanfattning : Internet of Things (IoT) is a system of interrelated computing devices with the ability to transfer data over the network and collected by the applications that rely on fresh information, where the freshness of data can be measured by a metric called Age of Information (AoI). Age of Information is the time that is measured by the receiving node from the time the data has generated at the source. LÄS MER

  3. 3. An Internet of Things Software and Firmware Update Architecture Based on the SUIT Specification

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

    Sammanfattning : IoT devices are   increasingly used in the process of gathering scientific data. In   environmental monitoring IoT devices can be used as remote sensing devices to   collect information about e.g. temperature. LÄS MER

  5. 5. Exploring the Possibilities of Robustness Testing of CoAP Implementations Using Evolutionary Fuzzing

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

    Författare :Fredrik Liljedahl; [2019]
    Nyckelord :;

    Sammanfattning : Internet of Things (IoT) is a widely used expression to denote the connection of physical objects in the internet. IoT devices are attractive targets for malicious actors as they are often deployed in large numbers with the same software. Such software is important to test in order to prevent malicious abuse.
