  1. 6. Evaluating the functionality of an Industrial Internet of Things system in the Fog

    M1-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Mathias Granlund; Christoffer Hoppe; [2018]
    Nyckelord :IoT; IIoT; Fog; Cloud; Closed-loop control system; RPL; 6LoWPAN; Contiki-OS; Cooja; TmoteSky; IEEE 802.15.4; CoAP;

    Sammanfattning : The Internet is one of the greatest innovations ever created by mankind, and it is a technical trend that has moved into industries to facilitate automation, supervision and management in the form of IoT devices. These devices are designed to be extremely lightweight and operate in low-power and lossy networks, and therefore run a low duty cycle and CPU-clock frequency to reserve battery life. LÄS MER

  3. 7. Energy-Efficient Communication with Lightweight M2M in IoT Networks

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carlos Gonzalo Peces; [2018]
    Nyckelord :IoT; LwM2M; low power consumption; TSCH; Contiki-NG; Eclipse Leshan.; IoT; LwM2M; låg energiförbrukning; TSCH; Contiki-NG; Eclipse Leshan.;

    Sammanfattning : OMA’s Lightweight Machine to Machine (LwM2M) is an application protocol for device management in the Internet of Things (IoT) that has been recently published and widely adopted in a lot of projects. The protocol is designed to operate in sensor networks and machine-to-machine environments, where one of the main constraints is the energy consumption since the nodes are usually battery powered.

  4. 8. Digital Certificates for the Internet of Things

    Master-uppsats, KTH/Nätverk och systemteknik

    Författare :Filip Forsby; [2017]
    Nyckelord :Cyber security; constrained devices; digital certificates; Contiki OS; inter- net of things; embedded systems.; Cybersäkerthet; begränsade enheter; digitala certifikat; Contiki OS; inter- net of things; inbyggda system.;

    Sammanfattning : This thesis will investigate the possibility of developing a lightweight digitalcertificate solution for resource constrained embedded systems in 6LoWPANnetworks. Such systems are battery powered or energy harvesting devices whereit is crucial that energy consumption and memory footprints are as minimalas possible. LÄS MER

  5. 9. Operating systems for resource constraint Internet of Things devices: An evaluation

    Kandidat-uppsats, Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Författare :Andreas Elvstam; Daniel Nordahl; [2016]
    Nyckelord :IoT; IoT OS; BLE; Contiki; RIOT; mbed; Zephyr; 6LoWPAN; IEEE 802.15.4; Evaluation;

    Sammanfattning : Internet of Things (IoT) är ett område under omfattande utveckling, både vad det gäller hårdvara och mjukvara. När det gäller hårdvaruplattformar för IoT enheter finns det platt-formar som är kraftfulla nog att exekvera ett reguljärt OS som t.ex. Linux. LÄS MER

  7. 10. Indoor Positioning using Ultra-wideband Technology

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Marcus Utter; [2015]
    Nyckelord :;

    Sammanfattning : This report evaluates the performance of an Indoor Positioning System (IPS) using Ultra-Wideband (UWB) technology. The purpose of this report was to evaluate if an UWB based IPS is suitable for localising smaller objects in a household environment. LÄS MER
