Abstract: The present invention relates to a decentralized IoT-based worker safety monitoring system for hazardous and unstructured work environments, including mines, tunnels, industrial sites, oil and gas facilities, disaster zones, warehouses, and remote infrastructure areas. The system comprises a plurality of wearable worker safety nodes configured to monitor physiological, environmental, motion-related, and operational parameters associated with workers and their surroundings. Each node includes an edge-processing unit for local sensor fusion, hazard detection, anomaly analysis, risk classification, and emergency prioritization without continuous dependence on cloud connectivity. Each wearable node further includes a peer-to-peer wireless communication module configured to form an adaptive decentralized mesh network with neighboring nodes. Upon detection of a hazardous condition, the node automatically generates an emergency event packet containing hazard type, severity, worker status, environmental information, location-related data, timestamp, and priority level. The packet is then propagated through neighboring nodes using adaptive multi-hop communication. The invention further provides collaborative hazard verification, wherein multiple worker nodes validate detected anomalies using distributed sensing information to improve alert accuracy and reduce false alarms. The system also supports adaptive routing, self-healing communication pathways, energy-aware operation, and optional synchronization with supervisory infrastructure when connectivity is available. Accordingly, the invention provides a resilient, low-latency, and infrastructure-independent worker safety ecosystem that improves emergency communication, enhances worker survivability, reduces centralized infrastructure dependency, and enables autonomous emergency coordination in hazardous industrial environments..
