IOT EDGE SYSTEM FOR SHARING RESOURCES AMONG IOT EDGES HAVING HIERARCHICAL STRUCTURE
An Internet of Things (IoT) edge system enables resource sharing among hierarchically structured IoT edges. The system includes IoT devices that register service lists with IoT edge devices in the same network and process service execution requests. Each IoT edge device includes middleware that manages services, sets publication status, and controls access rights. The IoT edge devices form a tree-shaped hierarchical structure where higher-layer devices receive published service lists from lower layers and have access rights to those services. Higher-layer devices can generate super services by combining services from multiple layers, enabling efficient resource utilization across the hierarchical IoT network.
