  1. 1. Dynamic configuration of Bluetooth mesh : A master thesis in electrical engineering

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

    Författare :August Fricking; [2022]
    Nyckelord :Bluetooth; Bluetooth mesh; BLE; BLE mesh; mesh networks; nRF52840; nRF52832; Dynamic configuration; adoptive configuration; mesh automation;

    Sammanfattning : When choosing what IoT protocol to use today, there are lots of choices. If a mesh type network is chosen, Bluetooth mesh might be a possible candidate. Bluetooth mesh without correctly configured parameters can however suffer from congestion and packet loss if the network is very dense or consists of many nodes. LÄS MER

  3. 2. 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.

    Sammanfattning : This thesis investigates two aspects of the protocol IO-Link Wireless (IOL-W), a wireless derivative of the widely established network protocol for industry automation IO-Link (IOL). There is an increasing interest in using wireless solutions within the automation industry. LÄS MER

  5. 4. Implementation and performance analysis of multiple concurrent WPAN protocols on a system-on-chip

    Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Juni Hag; [2022]
    Nyckelord :Bluetooth; Bluetooth Low Energy; BLE; Zigbee; 802.15.4; IEEE 802.15.4; WPAN; wireless protocols; sensor networks; IoT; Internet of Things; multiprotocol; TDMA; SoC;

    Sammanfattning : The development of new energy efficient Wireless Personal Area Network (WPAN) protocols is a big factor for the increased interest in Internet of Things (IoT). However, the many protocols with overlapping applications have led to competing standards and sensor networks using different protocols, even to perform the same tasks. LÄS MER

  7. 5. Aggregator to connect in-body sensors to the health record system

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Pedro Gomes Freire; [2021]
    Nyckelord :;

    Sammanfattning : Wireless connected Implanted Medical Devices are becoming more and more common. Also, the increasing connectivity of medical sensors opens room for improving one important field of Health Care, Remote Patients Monitoring. LÄS MER
