The ZigBee module supports a variety of network topologies, enabling devices to form self-organizing networks and communicate. The following are common ZigBee module network topologies:
Star Network: A star network is the simplest topology, in which a central device (usually called a coordinator or coordinating device) acts as the center of the network, and other devices are directly connected to the central device. All data flows are forwarded and managed through the central device. A star network is suitable for small-scale applications where the number of devices is relatively small and concentrated in one area.
Tree Network: A tree network forms a hierarchical structure through branch connections, similar to the shape of a tree. The central device still exists, but other devices can be connected through intermediate devices to form branches. The data flow is forwarded through the intermediate device, and finally reaches the central device. The tree network is suitable for applications with hierarchical structure or data flow requirements, and can cover a large area.
Mesh Network: Mesh network is the most powerful and flexible topology of ZigBee. In a mesh network, all devices can be connected to each other to form a multi-hop transmission path. Each device can be used as a router or terminal device to forward data through multiple relay nodes. This structure allows data to be transmitted over multiple paths in the network, improving coverage and network robustness. Mesh networks are suitable for complex application scenarios, such as large-scale Internet of Things, industrial automation, and smart buildings.
In a ZigBee network, the selection and arrangement of devices depends on specific application requirements. Different network topologies can provide different advantages and applicability, and can be flexibly networked and adjusted according to needs.
