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

    University essay from KTH/Hälsoinformatik och logistik

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

    Abstract : 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.

  3. 2. Time synchronization error detection in a radio access network

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Moulika Madana; [2023]
    Keywords : GNSS - Global Navigation Satellite System; OAS - Over-the air-synchronization; PRTC - primary reference time clock; PTP - precision time protocol; Gauss Jordan elimination; GNN- Graph Neural Network; GNSS -Globalt navigationssatellitsystem; OAS - Över-the-air tidssynkronisering; PRTC - Primär referenstidklocka; PTP - Precisionstidprotokoll; Gauss Jordan eliminering; GNN- Graf neurala nätverk;

    Abstract : Time synchronization is a process of ensuring all the time difference between the clocks of network components(like base stations, boundary clocks, grandmasters, etc.) in the mobile network is zero or negligible. It is one of the important factors responsible for ensuring effective communication between two user-equipments in a mobile network. READ MORE

  4. 3. TSN Distributed Clock : An analysis of relationships between network configuration parameters and the resulting precision of time synchronization

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jakob Götberg; Jakob Olsson; [2023]
    Keywords : Time Sensitive Networking TSN ; IEEE 802.1AS; Ethernet; Time Aware Shaper TAS ; Real-time Communication; Time Sensitive Networking TSN ; IEEE 802.1AS; Ethernet; Time Aware Shaper TAS ; Realtids kommunikation;

    Abstract : In real-time systems spanning a network, there is a need for deterministic communication. The best-effort approach which most of the Internets traffic follows is not suitable for this area since it does not guarantee packet delivery within a deadline and there is also no accurate measure of when the packet was sent.

  5. 4. Distributed Relay/Replay Attacks on GNSS Signals

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Malte Lenhart; [2022]
    Keywords : Global Navigation Satellite System GNSS ; Spoofing; Relay Replay Attack; Software Defined Radio SDR ; Security; Satellitnavigeringssystem; Spoofing; Relay Replay Attack; Software Defined Radio SDR ; Säkerhet;

    Abstract : In modern society, Global Navigation Satellite Systems (GNSSs) are ubiquitously relied upon by many systems, among others in critical infrastructure, for navigation and time synchronization. To overcome the prevailing vulnerable state of civilian GNSSs, many detection schemes for different attack types (i.e. READ MORE

  6. 5. Data Analysis for Hearability and Synchronization in Telecom Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sun Xin; [2022]
    Keywords : 5G; Time Synchronization; Machine Learning; Deep Learning; 5G; Tidssynkronisering; Maskininlärning; Djupinlärning;

    Abstract : In a wireless communication system, synchronization is one of the most critical functions. Good timing and synchronization can prevent messages of the communication system from interfering with each other and enable a smooth message transfer. READ MORE
