Systematic Review of Smart Home Automation Technologies Based on IoT

Abstract

The rapid evolution of IoT technologies has changed smart home automation, improving residential convenience, energy efficiency, and security. Even with these advancements, a thorough implementation and use of IoT in smart homes still needs further thorough assessment, especially when it comes to unresolved issues and new constraints. This critical analysis reviews present IoT- based smart home automation studies in areas like security structures, energy control, blockchain utilization, anomaly spotting, and user verification, as well as advancements in load tracking, activity identification, and intrusion detection. While some research covers topics like energy harvesting and cybersecurity, there is a lack of comprehensive, methodologically rigorous evaluations of the limitations and compatibility of these technologies. This review categorizes and assesses the quality of research methods used in articles published from January 2017 to June 2024, finding that only a small number of studies meet rigorous research criteria. The results emphasize the importance of established methods and innovative strategies like federated learning for protecting data privacy, using AI-driven anomaly detection, and harnessing blockchain for IoT security to tackle scalability, privacy, and real-time adaptability challenges. This review aims to aid in the advancement of IoT technologies in smart homes by pinpointing research gaps and proposing future pathways for more resilient, efficient, and user-centric solutions, ultimately boosting the wider adoption and improvement of IoT technologies in residential settings.
