  1. 1. 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

  3. 2. IoT Framework for Water Monitoring Using the M-Bus Interface

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

    Författare :Albert Asratyan; Mandar Joshi; [2019]
    Nyckelord :Smart water monitoring; Contiki-OS; Internet of Things IoT ; M-Bus; MQTT; 6LoWPAN; Smart vattenmätning; Contiki-OS; Sakernas Internet IoT ; M-Bus; MQTT; 6LoWPAN;

    Sammanfattning : Immense amounts of water are wasted daily, and it is as important as ever to optimize our water consumption, especially considering that today around 850 million people lack access to clean water. With the rise of the Internet of Things, creating a monitoring system for this purpose becomes easier, but there arises a problem of interfacing water meters to IoT capable devices. LÄS MER

  4. 3. 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

  5. 4. 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

  7. 5. 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
