This thesis explores the question: is it possible to synchronize twin state with practically low bandwidth requirements while simultaneously satisfying required accuracy constraints? To study this question, we present TwinSync, a framework that can be utilized to construct flexible real-time representations of deployed IoT systems and efficiently synchronize relevant system states with the twin, over a communication bottleneck, within a configurable application-specific notion of error (henceforth referred to as weak synchronization). Our approach is optimized to achieve data transfers utilizing less bandwidth without compromising the ability of the twin to replicate real-time system states within the specified approximate synchronization semantics. We evaluate the efficacy of TwinSync’s synchronization by conducting both a synthetic analysis and a case study based on a real-life application prototype. Our evaluation indicates that using TwinSync can provide the same or greater accuracy (in many cases) while sending significantly fewer bytes than a bandwidth-insensitive synchronization approach. The result is attributed to a more judicial selection of data to transmit over bottlenecks, compared to bandwidth-insensitive approaches."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["A digital twin synchronization protocol for bandwidth-limited IoT applications"]}]}],"canonical_facts":{"dc:contributor":["Caesar, Matthew"],"dc:creator":["Kalasapura, Deepti"],"dc:date":["2023-05","2023-04-04"],"dc:description":["Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-05-01","The student, Deepti Kalasapura, accepted the attached license on 2023-03-30 at 19:21.","The student, Deepti Kalasapura, submitted this Thesis for approval on 2023-03-30 at 19:32.","This Thesis was approved for publication on 2023-04-04 at 14:58.","DSpace SAF Submission Ingestion Package generated from Vireo submission #18883 on 2023-09-01 at 17:13:05","Digital Twins are evolving as a key component in modern systems with diverse applications like remote prognostics, optimizing run-time operation, anomaly detection, and more.
