  1. 6. Learned Multi-Sensor Indoor Positioning of Mobile Devices

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Christoffer Kjellson; [2021]
    Nyckelord :Indoor Positioning; Deep Learning; Fingerprinting; RSSI; Machine Learning; Pedestrian Dead Reckoning; Kaggle; Sensor Fusion; SDAE; LSTM; Technology and Engineering; Mathematics and Statistics;

    Sammanfattning : Attenuation of the microwave signal used in the Global Positioning System (GPS) due to interaction with building structures complicates the task of accurate indoor positioning. For this reason, research on alternative approaches is being performed at universities and companies worldwide. LÄS MER

  3. 7. Cooperative Beacon Rate Adaptation for Vehicular Ad-hoc Network

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

    Författare :Jinru Li; [2021]
    Nyckelord :;

    Sammanfattning : In Vehicular Ad-hoc Networks (VANETs), the vehicles need to periodically exchange current mobility status information with neighboring vehicles through beacon messages. The mobility status includes, among others, speed, position, and direction of the vehicle, which help vehicles to keep awareness of neighboring vehicles for better traffic efficiency and safety.

  4. 8. Indoor Positioning and Machine Learning Algorithms

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Raavi Uttarwar; Julián Valentín; [2021]
    Nyckelord :Indoor Positioning; Machine Learning; Bluetooth Low Energy; Technology and Engineering;

    Sammanfattning : This master thesis focuses around improving the efficiency and accuracy of existing indoor positioning systems with the help of Machine Learning (ML). Our work is based on Bluetooth Low Energy (BLE) v5.1. Position estimation is currently being carried out using the Least-Squares (LS) method in the framework. LÄS MER

  5. 9. Evaluating implementation areas of Real-Time Location System (RTLS) in the production at Scania CV AB Oskarshamn

    Master-uppsats, Lunds universitet/Teknisk logistik

    Författare :Gustav Nacke; Samuel Hirschfeld; [2021]
    Nyckelord :Real-Time Location System; Track and trace; Logistics; RTLS implementation; Scania CV AB; Conceptual framework; Technology and Engineering;

    Sammanfattning : Background Scania’s production unit in Oskarshamn manufactures and supplies truck cabs to the European market. In order to remain competitive, it is necessary for the company to re-evaluate its competencies and technologies. LÄS MER

  7. 10. BLE Beacon Based Indoor Positioning System in an Office Building using Machine Learning

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap
