Abstract

The new wave of computing allows users to explore their time in the Internet of Things (IoT) by connecting their smart devices over the network for data transfer without human interventions. While this swing increases the pace in IoT, time synchronization became a demanding feature on IoT devices for real-time applications. In this paper, we describe two synchronization protocols in IoT, its features and the advantages over the other. In addition, this work reveals the importance of time synchronization in the IoT platform and the effects of bad syncs in real-time applications. We start our research by analysing the widely using Simple Network Time Protocol (SNTP) and its performance in terms of offset and delay to examine the accuracy and reliability to define the synchronization.
