Introduction to multi-hop network of wireless MESH technology

I believe that friends who understand wireless Mesh technology should have heard of Mesh network's unique multi-hop network technology. Multi-hop network is a new wireless network technology that is completely different from traditional wireless networks. There are very important applications in the field of modern wireless transmission. Today, Tengyuan Zhituo Xiaobian will lead everyone to understand the multi-hop network in wireless Mesh technology.

In the traditional wireless access technology, a point-to-point or point-to-multipoint topology is mainly used. There is typically a central node in such a topology, such as a base station in a mobile communication system, an access point (AP) in an 802.11 wireless local area network (WLAN), and the like. The central node in this structure is connected to the wireless link of each wireless terminal by a single-hop method to control the access of each wireless terminal to the wireless network; at the same time, it is connected to the wired backbone network through a wired link to provide a connection to the backbone network. . In the wireless Mesh network, its unique mesh Mesh topology is a multi-point to multi-point network topology. In this Mesh network structure, each network node is connected in a wireless multi-hop manner through neighboring other network nodes.

In practical applications, MESH multi-hop network technology has the following advantages.

1, easy to install

Installing the Mesh node is very simple. Take the device out of the box and plug it in. By greatly simplifying the installation, users can easily add new nodes to expand the coverage and network capacity of the wireless network. In a wireless mesh network, not every Mesh node requires a wired cable connection, which is the biggest difference from a wired AP.

2, flexible structure

In a single-hop network, devices must share APs. If several devices are to access the network at the same time, communication congestion may occur and the system may be slowed down. In a Mesh multi-hop network, devices can connect to the network through different nodes at the same time, so it does not cause system performance degradation. The Mesh network also provides greater redundancy and communication load balancing. In a wireless mesh network, each device has multiple transmission paths available, and the network can dynamically allocate communication routes according to the communication load condition of each node, thereby effectively avoiding communication congestion of the nodes. Single-hop networks do not dynamically handle communication interference and overloading of access points.

3, high bandwidth

In the wireless transmission process, as the wireless transmission distance increases, various signal interferences and other factors that cause data loss also increase. Mesh networks transmitting data through multiple short hops will be an effective way to achieve higher network bandwidth. In a mesh network, a node can not only transmit and receive information, but also act as a router to forward information to nearby nodes. As more nodes are connected and the number of possible paths increases, the total bandwidth is also greatly increased. Secondly, Mesh multi-hop networks usually use lower power to transmit data to neighboring nodes, and the wireless signal interference between nodes is also small. The channel quality and channel utilization efficiency of the network are greatly improved, so that higher network capacity can be realized.
