Abstract

Sinkronizacija prijenosnih uređaja korištenjem bežičnih tehnologija jedan je
od još uvijek aktivnih problema u IoT svijetu. S obzirom na ograničenja količine
energije i razine performansi mikrokontrolera, potrebno je implementirati
različite načine kako bi se postigla optimalna razina sinkronizacije sa što manje
resursa.U radu su detaljno proučeni i implementirani razni sinkronizacijski algoritmi
bazirani na BLE komunikaciji radi sinkronizacije više ESP32 uređaja u
stvarnom vremenu. Zbog limita same tehnologije zaključak je da je moguće postići konzistentnu
sinkronizaciju u razini nekoliko milisekundi uz minimalnu potrošnju energije.

Abstract (english)

Synchronizing portable devices using wireless technologies is one
of the still active issues in the IoT world. Given the quantity restrictions
energy and performance levels of microcontrollers, it is necessary to implement
various ways to achieve the optimal level of synchronization with as few resources as possible. In the paper, different synchronization algorithms were studied and implemented in detail
based on BLE communication to synchronize multiple ESP32 devices in
real time. Due to the limits of the technology itself, the conclusion is that it is possible to achieve consistent synchronization at the level of a few milliseconds with minimal energy consumption.
