Seminar: Low Overhead and Application-Oriented Synchronization in Heterogeneous Internet of Things Systems

#time #synchronization #IoT

Recent evolution in the Internet of Things (IoT) and Cyber-physical systems (CPS) is expected to change the everyday life of its users by enabling low latency and reliable communication, coordinated task execution, and real-time data processing among pervasive intelligence through the communication network. Precise time synchronization, as a prerequisite for a chronological ordering of information or synchronous execution, has become a vital constituent for many time-sensitive applications.

On the one hand, Internet of Things (IoT) systems rely heavily on the temporal coherence among its distributed constituents during data fusion and analysis, however, the existing solutions for data synchronization, do not easily tailor to resource-constrained scenarios. On the other hand, timestamping accuracy is of the utmost importance to achieve accurate time synchronization of large-scale connected systems, however, the heterogeneity and complexity inherent to the Internet of Things (IoT) systems lead to multi-source timestamping uncertainties and significantly deteriorate the performance of traditional inflexible synchronization methods. Therefore, this talk aims at investigating these challenges by proposing a low overhead and application-oriented synchronization in heterogeneous IoT systems.
