Cyber-Physical Systems (CPS) refer to the next generation of ICT systems that mainly integrate sensing, 10 computing, and communication to monitor, control, and interact with a physical process to provide citizens and busi- 11 nesses with smart applications and services: healthcare, smart homes, smart cities, and so on. In recent years, healthcare 12 has become one of the most important services due to the continuous increases in its costs. This has motivated extensive 13 research on healthcare CPS, and some of that research has focused on describing the software architecture behind these 14 systems. However, there is no secondary study to consolidate the research. This paper aims to identify and compare 15 existing research on software architectures for healthcare CPS in order to determine successful solutions that could guide 16 other architects and practitioners in their healthcare projects. We conducted a systematic literature review (SLR) and 17 compared the selected studies based on a characterization schema. The research synthesis results in a knowledge base of 18 software architectures for healthcare CPS, describing their stakeholders, functional and non-functional features, quality 19 attributes architectural views and styles, components, and implementation technologies. This SLR also identifies research 20 gaps, such as the lack of open common platforms, as well as directions for future research.
