Internet of Things Search Engine: Concepts, Classification, and Open Issues
This provides a foundational framework for researchers and developers in IoT to navigate and advance the field, though it is incremental as it synthesizes existing work rather than proposing new methods.
The article tackles the challenge of organizing the immature field of Internet of Things Search Engines (IoTSE) by introducing concepts and a meta-path model to classify systems based on functionality, categorizing over 200 works from a decade of research into eight groups.
This article focuses on the complicated yet still relatively immature area of the Internet of Things Search Engines (IoTSE). It introduces related concepts of IoTSE and a model called meta-path to describe and classify IoTSE systems based on their functionality. Based on these concepts, we have organized the research and development efforts on IoTSE into eight groups and presented the representative works in each group. The concepts and ideas presented in this article are generated from an extensive structured study on over 200 works spanning over one decade of IoTSE research and development.
