Tree-Based Hierarchical Structure

What is JOI’s Hierarchical Structure?

JOI arranges IoT hubs in a flexible, tree-like structure. Each hub (called a JOI hub) sits within a clearly defined hierarchy, allowing efficient communication, management, and collaboration across multiple levels—from individual rooms all the way up to entire campuses or cities.

Instead of a flat, complicated network, JOI simplifies management by clearly organizing hubs into upper and lower levels, each with specific roles and capabilities. This hierarchical arrangement enables JOI to easily scale, manage complex tasks, and maintain high performance without cloud dependence.

How Does Hierarchical Management Work?

① Clearly Defined Roles

Each JOI hub operates autonomously at its assigned level, handling local data and immediate tasks. Upper-level hubs manage broader, system-wide coordination, defining powerful Super Services that lower-level hubs can securely request.

② Simple, Flexible Scalability

Adding or removing hubs is easy—simply connect or disconnect them from their parent hub. This flexibility allows your IoT system to expand or restructure effortlessly without complicated configurations.

③ Enhanced Local Intelligence

By processing data at each hub, JOI ensures fast decision-making and responses without waiting for cloud-based communication. Localized processing also reduces network traffic, increasing efficiency and reliability.
