Research on cluster communication application of smart home Internet of Things

This paper designs a low-power, reliable Zigbee-based cluster communication system for smart homes, addressing delay, data stability, and energy efficiency. Tests on lighting, sockets, and door locks show response delays under 100ms, success rates above 94%, and daily power use under 30mWh. To resolve issues like congestion, security risks, and node failures, the study proposes optimized strategies—dynamic channel allocation, encryption, intelligent routing, and fault recovery—validated through models. The results support practical deployment and future development of smart home communication systems.
