Abstract
In the process of evolution to the next generation network, wireless is an indispensable technology. Because of its Multi-Hop characteristics, the application value of Wireless Mesh Network in the next generation Internet has been proved. Because of Mesh peer-to-peer network topology, if a node fails, it will not affect the operation of the whole network, and can effectively avoid single point of failure. As a solution to provide high-speed internet services, Wireless Mesh Network can provide network access for mobile users in its coverage area, and it has evolved into an effective solution for broadband home networks, community networks, enterprise networks and other wireless access networks.
