    Sammanfattning : Det är mycket dyrt att utveckla markinfrastruktur för att försörja hela jorden med internet. Detta ärspeciellt fallet i glesbebyggda områden då det finns lite ekonomisk vinning. Sverige som är ett stortoch glesbefolkat land har stora områden av denna typ. LÄS MER

  3. 2. Wireless Sensor Network for Controlling the Varroasis Spread within Bee colonies across a Geographical Region

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Venkat Sai Akhil Dasyam; Saketh Pokuri; [2024]
    Nyckelord :Wireless Sensor Networks; Monitoring and Control; Precision Beekeeping; Disease spread; Internet of Things.;

    Sammanfattning : Background: With the global decline of honey bee populations, safeguarding these vital pollinators has become crucial. Varroa destructor mites are a primary threat, weakening bees and facilitating the spread of diseases, which can decimate colonies and disrupt ecosystems. LÄS MER

  4. 3. Physical Layer Security for MIMOTransmission of Short PacketCommunications

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Varun Duvva; Bharath Reddy Anugu; [2024]
    Nyckelord :Physical Layer Security; Multiple-Input Multiple-Output; Short Packet communication; Maximum Ratio Combining; Maximum Ratio Transmission; and Beamforming;

    Sammanfattning : This thesis explores the practical application of Physical Layer Security (PLS) inMultiple-Input Multiple-Output (MIMO) systems, particularly focusing on ShortPacket Communication (SPC). The aim is to enhance the security of wireless com-munications against eavesdropping threats. LÄS MER

  5. 4. Control system and simplified timesynchronization for heterogenous IoT systems with medium time requirements

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Jemma Touma; Simon Hejdenberg; [2024]
    Nyckelord :Internet of Things; time synchronization; wireless sensor networks; network time protocol; Android; Bluetooth; WiFi Direct;

    Sammanfattning : The company QTPIE conducts research on drivers and their unconscious reactions when driving. To help, they use smart devices that today must be individually handled at the start and end of a run, and have individually set timestamps, which can lead to differences between the units when data is entered and collation of the units' data after a run.

  7. 5. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Franz Wikner; [2024]
    Nyckelord :Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

    Sammanfattning : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.
