    Sammanfattning : The Internet of Things (IoT) is widely adopted across various fields due to its flexibility and low cost. Energy-harvesting Wireless Sensor Networks (WSNs) are becoming a building block of many IoT applications and provide a perpetual source of energy to power energy-constrained IoT devices. LÄS MER

  3. 2. 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

  4. 3. Energy Efficient Communication Scheduling for IoT-based Waterbirds Monitoring: Decentralized Strategies

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Otabek Sobirov; [2022]
    Nyckelord :TSCH; 6TiSCH; RPL; scheduling; energy consumption; COOJA; autonomous scheduling; distributed scheduling; reinforcement learning; RL-based scheduling; Q-Learning;

    Sammanfattning : Monitoring waterbirds have several benefits, including analyzing the number of endangered species, giving a reliable indication of public health, etc. Monitoring waterbirds in their habitat is a challenging task since the location is distant, and the collection of monitoring data requires large bandwidth.

  5. 4. Integrating Jamming Detection into Low-power Mesh Networks

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Wenbo Xiao; [2022]
    Nyckelord :;

    Sammanfattning : In the field of the Internet of Things (IoT), jamming attacks and anti-jamming countermeasures have always been a very important research directions. Jamming attacks are aimed at disturbing routine wireless communications by sending out intentional radio interference, which leads to packet loss, higher energy consumption, and even disruption of the whole network.

  7. 5. UWB-TWR performance comparison in a hybrid node network

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Oskar Sundin; [2021]
    Nyckelord :UWB; TWR; CSMA; Token ring;

    Sammanfattning : This thesis investigated the performance of a positioning system that utilised UWB technology where devices regularly shifts between acting as an initiator and as a responder for distance measurements between each other. The goal was to investigate existing positional techniques and to implement a novel network where devices initiates and responds to distance measurement exchanges. LÄS MER
