  1. 1. Reproducibility and Applicability of a Fuzzy-based Routing Algorithm in Wireless Sensor Networks

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Hannes Rönningen; Erik Olofsson; [2023]
    Nyckelord :End-to-end delay; Energy-efficiency; Fuzzy logic; Lifetime maximization; Multi-hop network; Multiobjective optimization; Reinforcement learning; Routing; Routing-protocol; Shortest path; Wireless sensor networks; WSN localization;

    Sammanfattning : Wireless sensor networks is a broad subject with many applications and interesting research areas, such as optimization within connectivity and energy efficiency. One problem is that most published articles in this field use customized simulation environments and do not provide source code of their implementation. LÄS MER

  3. 2. Battery Driven Embedded System for Indoor Localization of Pneumatic Tools

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

    Författare :Kajsa Hjort; [2020]
    Nyckelord :Wireless localization; Internet of moving technology IoMT ; Sensor system; Industry 4.0 andWireless Sensor Networks WSN ; Trådlös lokalisation; Internet avMoving Things; sensorsystem; smarta system och trådlöst sensornätverk;

    Sammanfattning : As the rapid progress in technology changes our daily life, it also changes how the Industry works. The new developments enable technologies such as the Internet of Moving Things (IoMT), and through these technologies, new challenges arise. IoMT adds one more vital issue, localization, to be solved in comparison to the Internet of Things (IoT). LÄS MER

  4. 3. Synchronization of Acoustic Sensors in a Wireless Network

    M1-uppsats, Linköpings universitet/Datorteknik

    Författare :Malin Johansson; [2019]
    Nyckelord :Synchronization; GNSS; GPS; WSN;

    Sammanfattning : Geographically distributed networks of acoustic sensors can be used to identify and localize the origin of acoustic phenomena. One area of use is localization of snipers by detecting the bullet's shock wave and the muzzle blast. LÄS MER

  5. 4. Non-Coherent Radio-Based Positioning

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

    Författare :Farshid Rezaei; Mohamad Abou Nasa; [2019]
    Nyckelord :target localization and tracking; wireless sensor network WSN ; hybrid measurements; received signal strength RSS ; angle of arrival AoA ; Technology and Engineering;

    Sammanfattning : In this thesis, a new Angle-of-Arrival (AoA) technique is used to determine the direction of a target in an outdoor environment using Radio Frequency (RF) signals. This technique estimates the AoA based on the difference between the Received Signal Strength Indicators (RSSI) from two/four directive antennas. LÄS MER

  7. 5. Outdoor localization in long range WSN using trilateration

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

    Författare :Tom Karlsson; Mike Persson; [2017]
    Nyckelord :;

    Sammanfattning : This thesis report investigates how good position estimations that can be done outdoors with received signal strength indication (RSSI) trilateration for sub 1-GHz radio nodes. A custom network and an empirical distance model have been created as well as a technique for weighting multiple distance estimations, using wrapped normal probability density functions. LÄS MER
