The Internet of Things (IoT) for smart homes is a rapidly growing research area focused on creating intelligent, automated, and energy-efficient living environments through interconnected devices and systems. Research papers in this domain explore smart appliances, lighting, HVAC systems, security and surveillance, and personalized user services, leveraging IoT sensors, actuators, and communication networks. Key contributions include context-aware automation, energy management, AI-driven user behavior prediction, edge/fog computing for low-latency processing, and secure data sharing and privacy-preserving mechanisms. Recent studies also address interoperability among heterogeneous devices, scalable architecture design, and integration with cloud platforms and voice-controlled interfaces. By tackling challenges such as cybersecurity, reliability, and user adaptability, IoT-smart home research aims to enhance comfort, safety, energy efficiency, and overall quality of life in modern living spaces.
