 - We integrated **gyroscope-based time synchronization algorithm** instead of SNTP to demonstrate sync accuracy. The algoritm requires client and leader smartphone to be rigidly attached together and shaken for a few seconds. After that the recorded gyroscope data is processed and calculated offset is returned to the client smartphone. All the experiments have been carried out using two Samsung S10e smartphones.
