1. What is mesh networking? Wireless mesh network (wireless mesh network) is also called "multi-hop" network. In the mesh networking network, any device node can be used as a router and terminal, and each node in the network can send and receive signals.Module CAN-BUS Each node can communicate with one or more nodes. 2. Features of mesh networking Node interconnection: All nodes in the local area network are connected together, there are multiple connection channels between any two nodes, and it presents an obvious trend of decentralization. Self-configuration: The wireless Mesh network has automatic configuration and centralized management capabilities, which simplifies network management and maintenance. Self-healing: The wireless Mesh network can automatically discover and add routing connections, eliminate the impact of single point failures on services, and provide redundant paths. High utilization rate: In a single-hop network, a fixed central node is shared by multiple devices. With the increase of network devices, the availability of the communication network of the central node will be greatly reduced. In the mesh network, since each node is With the central node, such problems will not occur at all. Once the availability of a certain node drops, the data will automatically reselect a node for transmission.
Ebyte's mesh networking products include E18 series ZigBee products, E180 series ZigBee products, and Bluetooth series E104-BT10, E104-BT10-IPX, E104-BT11-PCB, E104-BT11-IPX; (E180-Z6907A only Can be used as a terminal node) 3. Star network The star structure uses the central node as the core, and other nodes are connected to the central node. This structure has high cost and low reliability, but its delay is small and the structure is simple Easy to manage; such as Ebyte's E70NW series products. 4. Comparison between mesh network and star network At present, the typical LAN layout adopts star structure or multi-layer star structure. The network is connected through the main router, then distributed to each sub-router, and finally connected to different hosts and on the device. Such wiring is relatively simple to implement and requires a relatively small number of cables.
This layout method and layout ideas span the era of wired and wireless. For example, in the home, users will access the network from network service providers such as China Telecom and China Unicom, and then transfer multiple signals or wireless signals through the wireless router for home use. Multiple wired and wireless devices are used, which is also a typical star structure.WiFi Wireless Module Mesh networking is fast in deployment, easy to install, flexible in networking, and better in network security and stability. In terms of network structure, mesh networking has more advantages. Of course, both networking methods have their own advantages and characteristics, and they need to be selected according to actual applications. That's all for today's sharing.
