We collected the dataset using two bibliographic databases: Clarivate Web of Science (WoS) and Scopus.This analysis's search string was: ``internet of things gateway'' OR ``IoT gateway'' whose dataset download date was January 27, 2020. We apply this string to the search for topics in WoS and Scopus, which includes title, abstract, author keywords, and KeyWords Plus R (forWoS). With these search criteria, we download the data set. Then we preprocess it in ScientoPy, where duplicate documents were filtered and removed. We took 413 documents with their bibliographic data to carry out a scientometric analysis with ScientoPy to extract the first 500 keywords from the main author. We then extracted the author keywords related to IoT Gateway implications from this list. We organized them into three different categories (Protocols, Validation, and Cloud Interface).
