Abstract
IoT systems are typically distributed and performing coordinated behavior across IoT, edge and cloud infrastructures. To fully realize the great potential of IoT systems, it is important to facilitate their creation and operation. It is crucial to have a clear picture of the research landscape of the existing approaches and tools for supporting the deployment and/or orchestration of IoT systems (D epo 4IoT). Such a picture can show us how advanced the current state of the art is and what are the gaps to address. We conducted a systematic mapping study (SMS) to find out the research landscape in this domain. The results of our SMS show a sharp increase in the number of primary D epo 4IoT publications in two recent years. We found that most approaches do not really support the deployment or orchestration at IoT devices level. Finally, we suggest some potential research directions to address the research gaps that have been found.
