  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.
