1. 1. 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. Low-Power Global Time Synchronization for the Contiki-NG Operating System

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Arnis Gustins; [2023]
   Nyckelord :;

   Sammanfattning : Time synchronization is a well-known problem in low-power embedded wireless networks. While many synchronization protocols exist, usually they are not standard-compliant or do not provide synchronization of a global calendar time which is required by many applications, such as event correlation and certificate validation.
