A wireless mesh network consists of mesh routers (mesh routers) and mesh clients (clients). The mesh routers form a backbone network and are connected to a wired internet network to provide multi-hop wireless internet connections for mesh clients.
Wireless Mesh networks (wireless mesh networks), also known as "multi-hop" networks, are a new type of wireless network technology that is completely different from traditional wireless networks.
In a conventional wireless local area network (WLAN), each client accesses the network through a wireless link connected to an AP (Access Point) to form a local BSS (Basic Service Set). If users want to communicate with each other, they must first access a fixed access point (AP). This network structure is called a single-hop network.
In a wireless mesh network, any wireless device node can act as both an AP and a router. Each node in the network can send and receive signals, and each node can directly communicate with one or more peer nodes.
The biggest benefit of this architecture is that if the nearest AP is congested due to excessive traffic, the data can be automatically rerouted to a neighboring node with less traffic. And so on, the packet can continue to be routed to the next node closest to it according to the network, until it reaches the final destination. This access method is multi-hop access.
In fact, the well-known Internet is a typical example of a Mesh network. For example, when we send an E-mail, the e-mail does not arrive directly in the recipient's mailbox, but is forwarded from one server to another through the router, and finally arrives at the user's mailbox after multiple route forwarding. In the process of forwarding, the router generally selects the most efficient transmission path so that the email can reach the user's mailbox as soon as possible.
Compared with the traditional switched network, the wireless mesh network removes the wiring requirements between nodes, but still has the redundancy mechanism and re-routing function provided by the distributed network.
In a wireless Mesh network, if you want to add a new device, you only need to simply connect it to the power supply. It can automatically configure itself and determine the best multi-hop transmission path. When adding or moving a device, the network automatically discovers topology changes and automatically adjusts the communication route to get the most efficient transmission path.
