The Internet of Things has brought unprecedented technological innovation to smart homes, but the impact of this change on technology and users is limited and dispersed. Based on a systematic literature review, the present research conducted a quantitative analysis of 2874 papers (published in 2008–2020) obtained from the Web of Science to bridge the research gap. The current research identifies the development status and trends, country distribution, and journal categories in this area. Then, based on the main topics covered by smart homes, we proposed a holistic research framework that integrates the infrastructure layer, the communications technology layer, the data analytics layer, and the user service layer. The framework analyzed wireless sensing networks, communication protocols, and security threats, as well as the activity identification process and user services, highlighting the lack of some degree of integration in this area. This study also discussed the evolution of hot spots in the field of smart homes and summarized potential future research directions. Finally, in the discussion section, this paper summarized the research contribution and compared the main proposed technical solutions. We hope this work will provide a solid basis for research and practical guidance for scholars and developers interested in smart homes based on the Internet of Things.

物联网为智能家居带来了前所未有的技术创新，但是这种变化对技术和用户的影响是有限的且分散的。基于系统的文献综述，本研究对从Web of Science获得的2874篇论文（于2008–2020年发表）进行了定量分析，以弥合研究差距。当前的研究确定了该领域的发展状况和趋势，国家分布以及期刊类别。然后，基于智能家居涵盖的主要主题，我们提出了一个整体研究框架，该框架将基础架构层，通信技术层，数据分析层和用户服务层集成在一起。该框架分析了无线传感网络，通信协议和安全威胁，以及活动识别过程和用户​​服务，突出说明了该领域缺乏某种程度的集成。这项研究还讨论了智能家居领域中热点的演变，并总结了潜在的未来研究方向。最后，在讨论部分中，本文总结了研究成果并比较了主要提出的技术解决方案。我们希望这项工作将为对基于物联网的智能家居感兴趣的学者和开发人员的研究和实践指导提供坚实的基础。本文总结了研究成果，并比较了主要提出的技术解决方案。我们希望这项工作将为对基于物联网的智能家居感兴趣的学者和开发人员的研究和实践指导提供坚实的基础。本文总结了研究成果，并比较了主要提出的技术解决方案。我们希望这项工作将为对基于物联网的智能家居感兴趣的学者和开发人员的研究和实践指导提供坚实的基础。
